— | 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. Technical characteristics I will add: microcontroller ATmega328 Life pressure, V 9 Support range 0.1 Ohm ... 50 MOhm Range of variable inductance 0.01 mH ... 20 H Range of variable capacity 25 pF ... 100000 uF Working strum, mA 25 Module dimensions, mm 72 x 59. | 50 | — | 1 PC. | — | — | — | — | — | — | — | |||||||||||||

— | The photo relay module activates the relay at a certain light intensity. The photoresistor, which is connected with a cable 20 cm long, determines the level of illumination. When light hits the photoresistor, it changes its resistance. Because of this, the voltage in the circuit changes, which signals the amount of light. The module can be used in projects that require the relay to be triggered in the presence of a given light brightness (street lighting, turning on car headlights, etc.). The board has an LM393 comparator that determines the light intensity across the photoresistor. The sensitivity level of the sensor can be adjusted using a trimmer resistor. The module does not have on and off timers. The relay is activated when the specified sensor sensitivity threshold is exceeded. If the illumination often changes its state, then the relay will operate frequently. The photoresistor is connected to the module using the COS pin. There are 2 terminal blocks on the module board: J1 (terminal 1): relay power is connected J2 (terminal 2): load connected There are also 2 LEDs on the board: D1: signals the power supply of the module D2: lights up when the specified sensor sensitivity threshold is exceeded You can supply power to the module board from an external power source.

The kit includes a set of parts, a board and a description of the assembly (the speaker is not included in the kit). Specifications: Coin detection depth 20 - 25 cm Depth of detection of large objects 100 - 150 cm Supply voltage, 9 - 14 V Current consumption, 60 - 70 mA Impulse current consumption, 1 - 2 A Board dimensions, 45 x 52 mm Circuit diagram Layout of elements General description: The device consists of two main nodes: transmitting and receiving. The transmitting node consists of a pulse generator on the NE555 chip and a powerful key on the IRF740 transistor. The receiving unit is assembled on a TL072 chip and a BC547 transistor. The excitation signal is transmitted periodically to the sensor coil, in the form of pulses with a duration of 125-150 μs and a frequency of 125-150 Hz. In conducting objects, damped eddy currents are induced, which excite a damped electromagnetic field. Depending on the conductive properties and the size of the object, the signal changes its shape and duration. Search coil manufacturing: For the manufacture of a search coil, you will need a rigid non-metallic mandrel Ø 200-250 mm, a copper winding enameled wire PEV (Ø0.4 - 0.6 mm) 20 meters long, a copper stranded insulated wire 2x1.5 mm2 120 - 150 cm long to connect the coil with payment. Wrap 25 turns of winding wire tightly onto the mandrel. Fix the ends of the wire and connect by soldering with a stranded insulated wire to the board to the contacts L1. Assembling and setting up a metal detector Solder an 8 ohm 0.5 W speaker to the SP1 contacts. The contacts P1 are powered by 9-14 V (preferably from a 12 V 1.2 Ah battery). After turning on the device, by rotating the tuning resistor R8, find a position where the clicks in the speaker will subside as much as possible, and the noise will not start to grow, after which, using the variable resistor R9, perform the same operation, but more accurately, the maximum sensitivity of the metal detector is at the threshold of sound. The sensitivity of a metal detector can be improved by changing the number of coil turns. With a mandrel diameter of 250 mm, and a winding wire of Ø0.5 mm, this is approximately 14 turns. After tuning is complete, the coil can be hardened by wrapping it with tape, electrical tape, or impregnating it with epoxy. It is recommended to varnish the soldered and debugged board. This will prevent the parameters from drifting when the environmental conditions change and ensure stable and reliable operation of the device.
