infrared (IR) sensor is a device that detects infrared radiation (heat) emitted by objects.
Specifications
Effective distance:2-30cm
Working voltage:3.3V-5V
Detection angle:35°
Circuit board size:3.2cm*1.4cm
The comparator uses LM393 for stable operation
The module can be powered by a 3-5 V DC power supply. When the power is turned on, the red power indicator light lights up
The detection distance of this sensor can be adjusted by a potentiometer, with characteristics such as low interference, easy assembly, and easy use. It can be widely used in robot obstacle avoidance, obstacle avoidance cars, assembly line counting, black and white line tracking, and many other occasions
