## Description

This adjustable infrared sensor features a high-sensitivity photoreflector to perform distance detection function,ranging from 3cm to 50cm. When the infrared light emitted by the emitter gets reflected on a surface that blocked it, the phototransistor can pick up the signal for distance calculation. Also a potentiometer for adjustment is arranged for easy and clear use. Compared with regular infrared sensor switch,it has advantages in distance, low interference by visible light, affordable, easy to assemble, easy to use, and can be widely used in robot obstacle avoidance, assembly lines and many other occasions. The obstacle detection distance can be adjusted with a potentiometer in copper screw, once done adjusting(e.g. max 60cm), the sensor will output low flat within the effective distance (e.g. obstructions at 40cm & 10cm ) to the microcontroller. SPECIFICATIONS Power supply: 5V Control Outout: 100mA when supply 5V Circuit consume: <25mA Response time: <2ms Direction: ≤15° Range: 3~50cm adjustable for opacity and transparent objects Shell marterial:plastic A low voltage output will be given when a object is in its detecting scope When connect to MCU pins, you need to add an 1~10K Ohm resistor for pull-up Sharp: 30mm(length) x 20mm(wide) x 13mm(thickness) with a 45cm lead wire DOCUMENTS Wiki (Adjustable Infrared Sensor Switch SKU:SEN0164) SHIPPING LIST Adjustable Infrared Sensor x1
