Technical summary
This module lets you evaluate distances between a moving object and the obstacles it meets. You just send a 10µs pulse to the input and the sensor returns a pulse width proportional to the distance.
Note: below 1cm and above 4m from an obstacle the module may crash. It must then be reset (cut off its power supply and restore it). It is therefore preferable to use this module indoors in a confined environment.
Power supply: 5Vdc
Consumption: 15mA
Frequency: 40kHz
Range: from 2cm to 4m
Trigger: positive 10µs TTL pulse
Echo signal: positive TTL pulse proportional to the distance.
Calculation: distance (cm) = pulse (µs) / 58
Dimensions: 45x21x18mm
