Description: It consists of three parts: PSD(position sensitive detector) and IRED (infrared detector), and signal processing circuit. Power supply voltage: 4.5 to 5.5 V 6. Accuracy is related to the number of AD bits collected and the conversion calculation formula. Triangulation method is adopted, and the material, ambient temperature and measurement time of the measured object will not affect the measurement accuracy of the sensor. The output voltage of the sensor corresponds to the detection range of 10-80cm wire feeding. Distance of the detected object can be obtained by measuring the voltage value, so this sensor can be used for distance measurement, obstacle avoidance and other occasions. Specification: Material: Electronic Components Product size: 45 x 19mm line length : 19mm Range of measurement: 20 to 150cm Signal output type: voltage analog signal Package size: 29.5 x 13 x 21.6mm Power consumption: nominal value of 33 mA Power supply voltage: 4.5 to 5.5 V. Package Includes:(3 Pack) 1 Piece Dupont Line 1 Piece Infrared Range Sensor Module
