HALJIA Infrared Digital Obstacle Avoidance Sensor Module Super Small 3-100cm Adjustable Current 6mA

Digital signal output, the sensor contains the necessary modulation and demodulation, logic processing. Ultra micro, and the design of mechanical mounting holes. Less power consumption, wide operating voltage range. The transmit signal is modulated by the modulation signal, the distance is far, the anti-interference is good, can work under the outdoor non direct sunlight (the distance will be shorter). Range adjustable, ranging from 3cm-100cm. To avoid the use of window technology to avoid the critical area of the problem, the sensor work is very stable, users directly use the output signal, do not need to consider the issue of signal jitter. Feature:Infrared Digital Obstacle Avoidance Sensor super Small 3-100cm Adjustable Current 6mA.Digital signal output, the sensor contains the necessary modulation and demodulation, logic processing.Working principle: the sensor active infrared emission, according to the reflected light detection, if detected obstacles, OUT foot output 0, otherwis
