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, otherwise 1 Working voltage: 3.8V-5.5V Operating current (5V): typical current 6mA Input / output signal (3 lines): VCC GND OUT GND, VCC is the power supply, the range of VCC is 3.8v-5.5v Multi circle precision adjustable potentiometer on the board, can be adjusted according to the use of the environment. Adjust range from 3cm-100cm. because it is the reflection principle, with the specific reflection of the target, can be adjusted according to the situation. There is a red LED on the circuit board, which emits light when obstacles are detected. OUT output keeps low level, and OUT output keeps high level when barriers are free. Obstacle detection time (effective detection range from the non-obstructing target to the presence of an obstacle, or the obstruction to the obstacle course to disappear) : ≤ 21m/s Sensor active infrared reflection detection, so the reflectance and shape of the target is the key to the detection distance, of which the black detection distance is the smallest and the white is the largest; the distance of small area objects is small, and the distance of large area is large. Module Size: 19 x 14mm Weight: 2.4g Packing List: 1 x Obstacle Avoidance Sensor
