Sharp IR Proximity Sensors are a series of infrared-based sensors developed by Sharp Corporation for detecting the presence of objects or measuring distances to objects in their proximity. These sensors use infrared light to determine the distance between the sensor and an object by measuring the time it takes for the emitted infrared beam to bounce back after hitting the object.

Product Details
The sensor has a Japanese Solderless Terminal (JST) Connector. We recommend purchasing the related pigtail below or soldering wires directly to the back of the module.
This sensor is great for sensing objects up to 5 feet away!
It consists of three parts: PSD (position sensitive detector) and IRED (infrared emitting diode) and signal processing circuit. Due to the triangulation method, the material of the measured object, the ambient temperature and the measurement time do not affect the measurement accuracy of the sensor. The sensor output voltage value corresponds to the detected distance. By measuring the voltage value, the distance of the detected object can be obtained, so this sensor can be used for distance measurement, obstacle avoidance and the like.
Specifications
Supply voltage: 4.5 to 5.5 V
Power consumption: nominal 33 mA
Packing size: 29.5 × 13 × 21.6 mm
Distance measurement range: 20 to 150 cm
Signal output type: voltage analog signal
Based on the principle of triangulation
Output is inversely proportional to distance
Analog output, requires microcontroller control with AD converter
The higher the AD number, the more accurate the distance measurement effect, and the 10-bit AD can reach 0.1cm.
