Product Specification:
- The output port OUT sensor module can be directly connected to the microcontroller IO port , you can directly drive a 5V relay ;
- The module detects the distance 2 -30cm, detection angle 35 °, the distance can detect potential is adjusted Can be used for 3-5V DC power supply modules
- When the power is turned on, the red power indicator light
- Using the comparator LM393
- Interface :
- 1. VCC: External 3.3V-5V voltage (can be directly connected to 5v MCU and 3.3v MCU)
- 2. GND: GND External
- 3. OUT: Small board digital output interfaces (0 and 1)
Warm tips:
The light sensor module have strong adaptable to the environment, having a pair of infrared transmitter and receiver, transmitter launch a certain frequency infrared, when meet obstacle in the detection direction, the infrared receiver is reflected back by the receiver tube, after processing through the comparator circuit, the green indicator light will illuminate while the signal output interface output digital signal (a low-level signal) can be adjusted via potentiometer knob detection distance, the effective distance range 2 ~ 30cm, working voltage is 3.3V-5V. The detection range of the sensor can be adjusted by the potentiometer, with little interference, easy to assemble, easy to use features, can be widely used robot obstacle avoidance, obstacle avoidance car assembly line count and black-and-white line tracking and many other occasions.

The adjustable Pot on the board is very temp sensitive, when temp drop below 35 degree F., then back to higher temps the unit has to get recalibrated. As the sensitivity and detection changes. If the pot is replaced with a better pot then the device word work greatly. I have tried at voltages between 3V to 5V DC and still sensitivity is unstable. Hope Design or MFG team can fix this issue. as I am designing this part into my project. or may have to use a micro switch.

Worked perfect out of the package. Used on my raspberry pi using the linesensor function of gpiozero in python.

I'm using it with a Raspberry Pi to control an IOT Relay. I have VCC connected to 5V and I get at least 30 cm of detection. I have a portable heater plugged into the IOT Relay and have it stay on for an hour after it last senses me at my computer.
