4 Channel Infrared Tracing Module


C-3, R-4 , I-2


Product ID: 20799 SKU: SEN-20799 Categories: , Tags: , , , , , ,

This 4 channel Infrared Obstacle Avoidance Proximity Sensors Module supports 4 IR transmitter and IR receiver pairs that sends out IR energy and look for reflected IR energy to detect presence of any obstacle in front of the sensor module. The module has on board potentiometer for each channel that lets user adjust detection range. The sensor has very good and stable response even in ambient light or in complete darkness.

The sensor module can be interfaced with Arduino, Raspberry Pi or any microcontroller having IO voltage level of 3.3V to 5V.
