No hay artículos en el carro The sensor module adaptable to ambient light, having a pair of infrared emitting and receiving tubes, transmitting tubes emit infrared certain frequency, when the direction of an obstacle is detected (reflection surface), the infrared reflected is received by the reception tube, After a comparator circuit processing, the green light is on, but the signal output interface output digital signal (a low-level signal).
You can adjust the detection distance knob potentiometer, the effective distance range of 2 ~ 30cm, the working voltage of 3.3V- 5V. Detection range of the sensor can be obtained by adjusting potentiometer, with little interference.
Feature:
1, When the module detects an obstacle in front of the signal, the green indicator lights on the board level, while the OUT port sustained low signal output, the module detects the distance 2 ~ 30cm, detection angle 35 °, the distance can detect potential is adjusted clockwise adjustment potentiometer, detects the distance increases; counterclockwise adjustment potentiometer, reducing detection distance.
2, The sensor active infrared reflection detection, target reflectivity and therefore the shape is critical detection distance. Where the minimum detection distance black, white, maximum; small objects away from a small area, a large area from the Grand.
3, the sensor module output port OUT port can be directly connected to the microcontroller IO can also be directly drive a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO
4, comparators LM393, stable;
5, the module can be 3-5V DC power supply. When the power is turned on, the red power indicator lights;
6, with the screw holes 3mm, easy fixed installation;
7, board size: 3.2CM * 1.4CM
8, each module has been shipped threshold comparator voltage adjusted by

Install on HO layout. These work great with a Radpberry Pi. Only issue was track lighting giving off IF Red and tripping the sensors. Change bulbs to LEDs and solved the issue. Fun working with them. Used to drive signals on the layout

3 units out of 10 are not functional and not getting any output even the power LED is on, fortunately I only need 6 and extra was spare parts.

Features:1, When the module detects an obstacle in front of the signal, the green indicator lights up at the board level and the OUT port keeps the signal output low, the module detects a distance of 2-30 cm,detection angle 35 °, adjusted clockwise adjustment potentiometer, distance can detect potential, detect increasing distance. Adjusted counterclockwise potentiometer, shortened detection distance.2, active infrared reflection detection of sensor, reflectance of target, therefore shape is critical detection distance.Minimum detection distance is black, white, maximum. Small objects away from small areas, large areas from ground.3, sensor module output port OUT port can be connected directly to the microcontroller. IO can also drive a 5V relay directly. Connection: VCC-VCC; GND-GND; OUT-IO4, Comparator LM393, Stable;5, Module can be 3-5V DC power supply. When powered on, red power indicator will be on;6 , Easy to fix if screw hole is 3mm;7, Board size: 3.2CM * 1.4CM8, Each module is shipped potentiometer adjusted threshold comparator voltage.PIN description :1 VCC 3.3V-5V External Voltage (5v and 3.3v MCU Can be directly connected to MCU)2 GND GND External3 OUT Small Board Digital Output Interface (0 and 1)

Funziona molto bene, ma punta massimo a 5 cm in tutte le condizioni migliori ! Non lo restituisco perché alla fine dei conti posso utilizzarlo per altri scopi ! Niente non lo consiglio per grandi distanze chiaramente !

Funziona bene, comunque difficilmente oltre i 10 cm a meno di non avvicinare uno specchio o un metallo riflettente.Per il resto ottimo rapporto qualità prezzo.
