Are you looking for a professional, yet affordable distance sensor? Are you in search of a sturdy, trustworthy tool that can do multiple jobs at once? If yes, look no furtherOur professional distance sensor must meet you needs. It is one of the best choices for you.Features- Color: As shown.- Material: Plastic.- Size: 3.5 x 3 x 2.16 cm.- Distance measuring range: 20-150cm.- Supply voltage: 4.5V-5.5V.- Consumption current: 4.5V-5.5V.- This is a distance measurement sensor module.- It consists of PSD (position sensitive detector) and IRED (infrared emitting diode) and signal processing circuit.- Because the triangulation method is used, the material of the measured object, the ambient temperature and the measurement time will not affect the measurement accuracy of the sensor.- The output voltage of the sensor corresponds to the detection distance.- The distance of the detected object can be obtained by measuring the voltage value, so this sensor can be used for distance measurement and obstacle avoidance.
