Description
The Infrared Obstacle Sensor Module has a built-in IR transmitter and IR receiver that send out IR energy and look for reflected IR energy to detect the presence of any obstacle in front of the sensor module. The module has an onboard potentiometer that lets users adjust the detection range. The sensor has a very good and stable response, even in ambient light or in complete darkness.
Obstacle Avoidance Sensors usually come in two types: with 3 and 4 pins.
Features:
Here are the specifications:
- When the module detects an obstacle in front of the signal, the green indicator light on the board level, while low-level continuous output signal OUT port, the module detects the distance 2 ~ 30cm, detection angle 35 °, the distance can detect potential is adjusted clockwise adjustment potentiometer to detect the distance increases; counterclockwise to adjust the potentiometer to reduce the detection distance.
- Active infrared sensors are needed to detect the reflected light, and thus the shape of the reflectivity of the target detection range is critical. The minimum detection distance is the black-and-white maximum: small objects from a small area; large objects from a large area.
- The output port OUT sensor module can be directly connected to the microcontroller IO port, and you can directly drive a 5V relay ; Connection : VCC-VCC; GND-GND; OUT-IO
- Using the comparator LM393, stable ;
- Can be used for 3-5V DC power supply modules . When the power is turned on, the red power indicator lights
- With the screw holes of 3mm , easy fixed installation ;
- Board size : 3.1 cm * 1.5 cm
- Each module shipments comparing the threshold voltage has been adjusted by the potentiometer is good , not exceptional circumstances, do not arbitrarily adjust the potentiometer.
