— | HC-SR04 is an ultrasonic sensor that allows you to measure the distance to an obstacle in the range from 2 to 400 cm. It can be used as a presence sensor in a smart home or security system, as well as for various robotic systems. In addition, using this module, you can make parking sensors for a car. The module is a board on which an ultrasonic emitter, a receiver and a control electronic circuit are placed. The sensor has small dimensions and a simple interface: two power outputs (VCC and GND), an input (TRIG) and an output (ECHO) for data transfer between the controller and the module. The emitter transmits a short ultrasonic pulse, which is reflected from the object and received by the sensor. The distance is calculated from the time to echo and the speed of sound in air. The receiver receives the echo signal and outputs the distance, which is encoded by the duration of the electrical signal at the output of the sensor. The next pulse can only be emitted after the echo from the previous one has disappeared. This time is called the cycle period. The recommended period between pulses should be at least 50 ms. If a 10 µs pulse is applied to the TRIG signal pin, the ultrasonic module will emit eight bursts of ultrasonic signal at a frequency of 40 kHz and detect their echo. The measured distance to the object will be proportional to the width of the echo pulse.

— | The FC-37 module is a high sensitivity humidity sensor and board designed based on the LM393 comparator. The LM393 chip processes and transmits the signal to the microcontroller in digital or analog form. This module can be used in projects where it is necessary that the device turns on when moisture interacts (in the detection of water leaks, in weather stations, etc.). The principle of operation of the module is to change the output voltage from the resistance of the sensor. If the board is wet, the resistance increases and the output voltage decreases, respectively, if the sensor is dry, then the resistance decreases, the voltage increases. The sensitivity of the sensor is adjusted using a potentiometer. There are 2 connectors on the module (J1, J2). J1 is required to connect the sensor to the module, and J2 is used to power the module and transmit the signal. An analog signal is transmitted via output A0, similarly, a digital signal is transmitted via contact D0. Contacts VCC and GND are designed to supply voltage to the module board. There are 2 indicators on the board: PWR-Led LED, which informs about the power supply to the module board, D0-Led lights up when a digital signal is transmitted to the device microcontroller. The voltage on the module board can be supplied from an external power source, Arduino Uno or other device designed on a microcontroller.

— | The DHT11 sensor is a popular sensor that is used to measure the temperature and relative humidity of the environment. This module can be used in the "smart home" system, in creating projects related to weather parameters, or in household projects. The sensor is not fast and accurate, but the sensor is often used in their first projects in the Arduino environment, because of its ease of use. The basis for the sensor are: thermistor and hygrometer. In addition to two sensors, the module has an integrated ADC in the form of a microcontroller (8-bit), which is necessary for converting analog humidity and temperature values into digital signals. The advantage of the sensor in comparison with its counterpart (DHT22) is its low cost. The sensor is connected to the Arduino board or other microcontroller devices using 3 pins (VCC, GND, S). The DHT11 sensor module board already has built-in components that make it easy to connect to the Arduino. To connect, you need to apply voltage to the VCC output from an external power source or microcontroller device and connect the common output of the GND module, and to transmit a digital signal, connect the S pin to the Arduino digital port. If you have an uninstalled DHT library in the Arduino IDE, then you can download and install it yourself. The kit consists of a DHT11 humidity and temperature sensor module board and 3 pieces of wires (female-female). Sensor Specifications: Supply voltage, V 3 ... 5.5 Humidity determination accuracy, % 20 ... 90 Temperature determination accuracy, °C 0 ... 50 Maximum polling frequency, Hz 1 Current consumption, mA 0.5 ... 2.5 Module dimensions, mm 15.5 x 12 x 5.5. | 5.7 | — | — | — | — | — | — | — | — | — | — | Arduino sensors | — | |||||||||

— | This model is one of the varieties of the Arduino Uno R3 board, which is made according to the original Arduino documentation. The main differences between the boards are: the method of mounting the ATmega328P microcontroller (the board is made in the form of SMD mounting), the presence of SDA (Serial Data) and SCL (Serial Clock) outputs, and the built-in CH340G chip. In all other respects, the board matches the Arduino Uno controller. The Uno R3 also has 14 digital ports, 6 analog ports, a power jack, a microUSB port, and a reset button. Chip CH340G designed by WCH, which serves to convert a computer USB interface into a serial UART interface, creating an additional UART port on the computer. The main advantages of this chip are: low price, compact package with a large number of pins and requires a minimum of external components. The board can be powered via an external power connector or USB port. As an external power source, you can use a battery or a conventional electrical network. The battery is connected to the GND and VIN outputs, and the AC adapter to the power connector. The recommended supply voltage for the controller is 7 - 12 V, but the board starts working when 6 - 20 V is present. Arduino Uno R3 has 3 types of memory: FLASH, SRAM, EEPROM. The platform has 32 KB of FLASH memory, where 2 KB is used for the bootloader, which stores programs. SRAM is a kind of random access memory that is used to store temporary data. EEPROM is a non-volatile memory that does not lose data in the absence of voltage. There are 14 digital ports on the board, which you can use depending on your project. The voltage range of the outputs is 5 V. The outputs are rated for 40 mA, but it is recommended to limit the input and output currents to 20 mA. The ports also have internal resistances of 20 - 50 kOhm, which are disabled by default. The platform has 6 analog ports (A0 - A5) for connecting sensors that use analog signals. The AREEF pin is used to regulate the input voltage between ground and the 5V output. For programming the microcontroller, the Arduino IDE software (which is a simplified version of the C ++ language) is used. This software development environment can be downloaded from the Arduino official website. For further work with the Arduino Uno R3 board, you need to install drivers for the CH340G chip. Due to the popularity of this microcircuit, many personal computers already have drivers for it installed, but if the drivers are not installed, you can download them and then install them yourself. The kit with the Arduino Uno R3 board includes pin extensions, but there is no USB cable for connecting to a computer. Extension cords are used, if necessary, to increase the contact pad of the microcontroller outputs. They are fixed on the board by soldering.

— | Hot characteristic: A mega tester was designed on the basis of the ATmega328 microcontroller, the COG12864 LCD display, a key button, a block, a quartz resonator and other additional components, to ensure the correct operation of the robot. I will add some special features: automatic switching on and easy calibration process. Change of parameters: For the help of the LCR-T4 mega tester, you can find out the parameters of such components: capacitor, resistor, conductor elements (transistor, diode) and inductance coil. Vimiruvach can designate the following parameters of electronic components: element opir inductance capacitor capacity Type and characteristics of the transistor /diode Transmission coefficient of the base of a bipolar transistor Bipolar transistor voltage FET gate capacitance Field-effect transistor voltage Voltage drop on diodes Parasitic capacitance of the diode In order to change the parameter of the component, it is necessary to turn on the power socket at the same time as the "Krona" battery. Let's then clean up the fixation from the block, pulling the important uphill, and place the necessary element in the block. If necessary, close the latch, pulling the valve down, and briefly press the control button. Let's use the mega tester LCR-T4 to automatically determine the characteristics of the element, which is installed into the bar. Catch your respect, when the capacitor capacity is reduced, it is necessary to discharge it! Calibration: Calibration of the tester is guilty of being carried out periodically as for any other vimiruvalnyh devices. In order to calibrate the switch, prepare two high-capacity capacitors (polypropylene, metal-filled ...) with a capacity of over 100nF and 4-30nF, as well as a jumper for switching three contacts in the test panel. Next, you need to install a jumper in contacts 1, 2, 3 and press the control button. When switched on, the screen will display "Self-test mode?". Press the button again to confirm. The calibration will be revealed. Dock the message "Isolation!" and remove the jumper. Self-calibration will continue until the capacitor symbol appears and the rating must be inserted. As a rule, during the first calibration, it is necessary to insert a capacitor on the back with a capacity of over 100 nanofarads, and then 4-30 nanofarads, and with advance only 4-30 nF. Completion of the calibration is accompanied by the revision of the software version and the "Test completed" notification. External calibration can be repeated by going to the menu and selecting the "Self test mode" item.

— | The HW-040 (KY-040) module consists of a rotation angle sensor (encoder) and auxiliary electrical components for stable operation of the sensor. An encoder is a mechanical sensor that reports the angle of rotation, rotation speed and direction of the axis of various devices. This module can be used to control servos or stepper motors. The HW-040 module has 20 fixed positions per revolution. These positions represent a small click when the encoder axis is rotated. The rotation angle sensor has 3 outputs, which are designated (A, B, C). The principle of operation of the encoder is to change the positions of the switches. One switch is responsible for connecting pins A and B, and the second for pins B and C. Each change in the position of the sensor axis changes the states of the switches. In addition, the encoder is equipped with a button that works when the shaft is pressed. The button can be used to select menu items of the device or to change the sensitivity of the sensor. A low TTL level appears on the sensor when the contacts are closed, then zero is applied to the CLK and DT pins. A high logic level is generated when a 5V supply voltage is applied. Pins CLK and DT transmit data about the rotation of the axis in the direction of clockwise or counterclockwise. CLK: encoder pin A DT: encoder pin B SW: defines the state of the button VCC (+): supply voltage GND: ground (pin C) As a power source, you can use an external power supply, the Arduino platform, or any other microcontroller device.

— | Mica for microwave ovens, dimensions 150x150 mm and thickness 0.4 mm, maximum temperature 500°C. It is widely used to make the protective plate of the wave channel (magnetron channel) in household microwave ovens. It is recommended to replace the protective mica plate at least once a year, depending on the intensity of use of the oven. Fat falling on the mica surface absorbs microwave radiation, which leads to a sharp decrease in useful power at the initial stage, and subsequently the mica itself, the magnetron cap burns out and, finally, the magnetron fails. | 19 | — | — | 100 pieces. | — | — | — | — | — | — | — | — | — | |||||||||
