IR Sensor Module With Preset

(Including GST)

IR Infrared Obstacle Avoidance Sensor Module with preset by ADIY has a pair of infrared transmitting and receiving tubes. When the transmitted light waves are reflected back, the reflected IR waves will be received by the receiver tube. The onboard comparator circuitry does the processing and the green indicator LED comes to life.

The module features a 3 wire interface with VCC, GND and an OUT pin on its tail. It works fine with 3v3 to 5V levels. Upon hindrance/reflectance, the output pin gives out a digital signal (a low-level signal). The onboard preset helps to fine tune the range of operation, effective distance range is 2cm to 10cm.

Description

Proximity Sensor are used to detect objects and obstacles in front of sensor. Sensor keeps transmitting infrared light and when any object comes near, it is detected by the sensor by monitoring the reflected light from the object. It can be used in robots for obstacle avoidance, for automatic doors, for parking aid devices or for security alarm systems, or contact less tachometer by measuring RPM of rotation objects like fan blades.

A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. An IR proximity sensor emits a beam of Infrared radiation and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor’s target.

The module works well for the distance 2 – 10cm and a detection angle 35 degree, The sensitivity of this can be adjusted by varying the potentiometer, the sensor module output port OUT port can be directly connected to the microcontroller IO can also be used to directly drive a 5V relay.
