HW201 Infrared (IR) Sensor Module

The HW201 comprises emitting and receiving tubes, transmitting tubes emitting certain infrared frequencies when it detects the obstacle, the sensor has the reception tube which receives that infrared frequency, Then there is a process of the comparator circuit. There is a green light that gets ON after that, The module also has a potentiometer through which one can adjust the detection distance.
Working:
TR Transmitter in the module emits Radiation. And, if the radiation gets reflected, the IR Receiver detects radiation and its resistance drops down, output goes low. If the radiation doesn’t get reflected, the Receiver doesn’t detect any Radiation, therefore its resistance rises, and output goes high.

APPLICATIONS:

• IR Imaging Devices 
• Security Devices 
• Flame monitors 
• Obstacle detection devices 
• Robotics 
• Gas detectors 
• Gas analyzers, etc

Features:

• 2 to 30cm adjustable sensing range (on-board Potentiometer) 
• 35-degree Detection Angle 
• LM393 Comparator Selection Output 
• Easy to use 
• Please note that the sensor sensitivity varies depending on the reflection surface applied

Package Includes:

• 1 x HW201 Infrared (IR) Sensor Module
