This module uses infrared emitter IR333C to emit infrared light, PT333-3B-L receives reflected infrared light, and compares it with comparator LM393 to judge if there is an obstacle in front.
When the module detects obstacles in front of the signal, the green indicator on the circuit board lights and at the same time the output low level signal, the detection module from 2 ~ 80cm, 35°detection Angle, test distance can be adjusted through the potentiometer. Adjusting the potentiometer clockwise increases the detection distance, Counter-clockwise decreases the detection distance.
The sensor module output can be directly connected to the microcontroller input pin, also it can drive a 5v relay directly.
This module can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, and many more.
- Operating voltage: recommended 3.3V / 5V (<10V can be)
- Module power consumption: 25mA ~ 40mA
- Detection distance: <=80cm (adjustable by adjustable resistance)
- Indicator light: power light + obstacle light
