Description
This sensor will allow you to measure distance by ultrasound of 2cm to 4 m approximately.
It is controlled manually by an entry or it will inject a pulse to 10µs that will generate ultrasound at 40 kHz, the output will provide an echo TTL signal proportional to the measured distance: Distance (cm) = Measured Echo Time (in µsec) / 58
Features
- Detection range: 2cm to 4 m
- Ideal detection angle: 15 °
- Power supply: 5V
- Consumption: 15mA
