Sell Obstacle avoidance module Infrared reflection photoelectric sensor best price

Send and receive years Effective range: 2 ~ 30cm Discovery of the angle: 35 degrees Operating voltage: 3.3 V to 5 V Size about 3.2 x 1.4 cm/1.26 x 0.55 inch If the module detects an obstacle in front of the signal, the green indicator lights on the board level, while the OUT terminal persists low signal output, the distance can detect potential clockwise adjusted potentiometer, the distance increases; Counterclockwise setting potentiometer, reducing the detection range. The sensor active infrared reflection detection, target reflective power and therefore the shape is crucial detection distance. Where the minimum detection distance is black, white, maximum; Small objects of a small area, a large area of ??the Grand. The sensor module output OUT connector can be directly connected to the minicontroller IO can also be directly connected to a 5V relay; Connector: VCC VCC; GND GND; OUT IO Comparators LM393, stable The module can be 3 5V DC power supply. When the power is turned on, the red light is lit. With the screw holes 3mm, easy fixed installation Each module has been sent Threshold comparator voltage across potentiometer well, not special case set, non-adjustable potentiometer VCC 3.3 V 5V external voltage (can be directly connected to 5V and 3.3V MCU MCU) GND GND External OUT small circuit board digital output interface (0 and 1) Main color: blue material: metal Package contains: 1 x obstacle avoidance sensor module Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
