Product description:
The main chip: LM393, photosensitive sensing probe
Operating voltage: 3-5V DC
Size: 30mm x 10mm x 13mm
Features:
The signal output indicator;
Single signal output;
Output effective signal is low, the indicator light;
Adjustable sensitivity (fine-tuning);
The output can be connected directly to the microcontroller I/O port.
Application:
automatic curtains, teaching experiment, light detection and so on for occasions;
Instructions:
1. The output form is a digital value,low voltage or high voltage. When the light is strong enough,the output signal is low.
2. It can be connected to the MCU directly to detect the light.
3. You can change the value of the potentiometer to change the threshold value.
Package contains:
1x Photoresistance Detection Optical Photosensitive Light Sensor
