Description
Digital proximity sensor performs the measurement with the method of time-of-flight. It operates in the range of from 3 to 200 cm with accuracy of +/- 3%. It is powered with the voltage from 3.3 to 5 V, it has a built-in voltage regulator, it communicates via the I2C bus. The module has necessary for the correct operation of the system, passive elements. The pin is a Gravity connector for connection of the module with the cable included in the set. Time-of-flight method is to measure the time from emmiting the pulse from an infrared to its return to the detector. It depends on the reflection of light from the object.
