Infrared Obstacle Avoidance IR Sensor Module
$ 0.29
- IR Sensor Module has a pair of IR transmitter and the receiver Diode, the infrared emitting tube emits certain frequency to encounters an obstacle detection (reflecting surface), the emitted ray reflected back to the receiver tube on receiving a comparator circuit process the frequency and the LED lights up, while the a digital signal output (a low-level signal) is activated. The sensor can be adjusted with the help of potentiometer knob to adjust the detection distance/range. The effective distance range of this sensor is 2 ~ 10cm working voltage of 3.3V-5V. Easy to assemble, easy to use features, can be widely used robot obstacle avoidance, obstacle avoidance car assembly line count and black-and-white line tracking and many other occasions. Features: When the module detects obstacles in front of the signal, the circuit board green indicator light level, while the OUT port continuous output low-level signals, the module detects a distance of 2 ~ 10cm, detection angle 35 °, the detection distance can be potential adjustment with adjustment potentiometer clockwise, the increase in detection distance; counterclockwise adjustment potentiometer, the detection distance decreased. the sensor active infrared reflection detection, target reflectivity and shape of the detection distance of the key. The black minimum detection range, white maximum; small area object distance is small, a large area from the large. The sensor module output port OUT can be directly connected with the microcontroller IO port can also be driven directly to a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO. The comparator using LM393, stable. 3-5V DC power supply module can be used. When the power is turned on, the red power LED is lit. With the screw holes of 3mm, easy to install. Board size: 3.1CM * 1.5CM. Each module in the delivery has threshold comparator voltage adjustable via potentiometer, special circumstances, please do not adjust the potentiometer. Interface(3-wire): VCC external 3.3V-5V voltage (can be directly connected with the a 5v microcontroller and 3.3v microcontroller). GND external GND. OUT board digital output interface (0 and 1). Specifications: Main Chip LM393 Operating Voltage (VDC) DC 3.6V ~ 5V Average Current Consumption 0.06mA Detection Angle 35° Distance Measuring Range 2 ~ 30CM Dimensions LxWxH 48 x 14 x 8mm Weight 5 gm Package Includes: 1 x Infrared Obstacle Avoidance IR Sensor Module. *Product Images are shown for illustrative purposes only and may differ from actual product.
