Module equipped with distance sensor based on Lidar technology. The sensor detects objects up to 130 cm and is powered from 3 V to 5.5 V. The board is equipped with one PWM digital output whose signal is similar to the servo control signal. The digital pin of the microcontroller can be used to measure the duration of each high pulse, which encodes the measured distance. Short range Lidar technology is used to accurately measure the time it takes for the emitted pulses of eye-safe infrared light to reach the nearest object and be reflected back. During sensor operation, continuous distance measurements are taken and ranges are coded as high pulse widths, which can then be synchronized by a microcontroller using a single digital input. A maximum range of 300 cm is only achievable for high reflectance targets in good environmental conditions. Targets with lower reflectivity or poor environmental conditions reduce the maximum range.
