This adjustable infrared sensor comes with a high - sensitivity photoreflector. It can perform distance detection from 3cm to 50cm. When the infrared light from the emitter reflects off an object, the phototransistor picks up the signal for distance calculation. There's a potentiometer for easy adjustment. Compared to regular infrared sensor switches, it has great advantages. It offers a good detection distance, is less affected by visible light, is affordable, easy to assemble and use. It can be widely used in robot obstacle avoidance and assembly lines. You can adjust the obstacle detection distance using a copper - screw potentiometer. After setting (e.g., up to 60cm), the sensor will send a low - flat signal to the microcontroller within the effective distance (like when there are obstructions at 40cm or 10cm). Specifications include a 5V power supply, a 100mA control output at 5V, a circuit consumption of less than 25mA, a response time of less than 2ms, a direction of up to 15°, an adjustable range of 3 - 50cm for opaque and transparent objects, a plastic shell, a low - voltage output when an object is in the detection range, and a need to add a 1 - 10K Ohm resistor for pull - up when connecting to MCU pins. It measures 30mm in length, 20mm in width, 13mm in thickness, and has a 45cm lead wire. There's a wiki available for the Adjustable Infrared Sensor Switch SKU:SEN0164, and the shipping list includes one Adjustable Infrared Sensor.
Using this adjustable infrared sensor is quite straightforward. First, make sure to power it with a 5V power supply. You can adjust the detection distance using the copper - screw potentiometer according to your needs. For example, if you want to set the maximum detection distance to 60cm, just turn the potentiometer until you reach the desired setting. When an object is within the detection range, the sensor will output a low - flat signal to the microcontroller. But when connecting it to the MCU pins, remember to add a 1 - 10K Ohm resistor for pull - up. As for maintenance, keep the sensor clean and avoid exposing it to excessive heat or moisture. If it gets dirty, you can gently wipe it with a soft, dry cloth. That's all you need to know to get the most out of this great adjustable infrared sensor.
