Features: 1. It consists of three parts: PSD (position sensitive detector) and IRED (infrared emitting diode) and signal processing circuit. 2. Using the triangulation method, the material of the measured object, the ambient temperature and the measurement time will not affect the measurement accuracy of the sensor. 3. The sensor output voltage value corresponds to the detected distance. 4. By measuring the voltage value, the distance of the detected object can be obtained. 5. Can be used for distance measurement, obstacle avoidance, etc. Specification: Condition: 100% Brand new Distance Measurement Range: 20-150 cm Signal Output Type: Voltage analog signal Power Consumption: Nominal 33 mA Supply Voltage: 4.5 to 5.5 V Accuracy is related to the number of AD bits collected and the conversion calculation formula. 10AD can generally reach 0.1cm. Size: Approx. 42 x 22 x 18mm / 1.7 x 0.9 x 0.7in Package List: 1 x Infrared Ranging Sensor 1 x Connecting Cable 1、It consists of three parts: PSD (position sensitive detector) and IRED (infrared emitting diode) and signal processing circuit. 2、Using the triangulation method, the material of the measured object, the ambient temperature and the measurement time will not affect the measurement accuracy of the sensor. 3、The sensor output voltage value corresponds to the detected distance. 4、By measuring the voltage value, the distance of the detected object can be obtained. 5、Can be used for distance measurement, obstacle avoidance, etc.
