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
