Description 10 Pieces Intelligent Car Infrared Obstacle Avoidance Sensor Module The IR sensor module consists of a pair of infrared transmitter and receiver tubes. The infrared tube emits a specific frequency when the detection direction encounters obstacles (reflecting the signal). The reflected infrared signal is processed by the comparator circuit, causing the green indicator to light up. Simultaneously, the signal output interface provides a digital signal output (a low-level signal). Function: The IR infrared obstacle avoidance sensor module can be used in robot obstacle avoidance, obstacle avoidance cars, line counting, black and white line tracking, etc. Adjustable Distance: The infrared module's detection distance is 2 to 30 cm, and the detection angle is 35 degrees. Easy to Use: The output sensor module can be directly connected to the I/O port of a microcontroller. You can also directly connect a 5V relay. Control Application: The IR sensor module can be used with 3-5V DC power supply modules. It has a red power indicator. Color: Blue Material: Polymer Package Contents: 10 x Infrared Sensor Module for Obstacle Avoidance Only the above package contents, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture to differ slightly from the actual product. The allowable measurement error is +/- 1-3 cm.
