The ElecFreaks HC-SR04 ultrasonic module measures distances and can be used with Arduino. It is triggered by a high-level TTL pulse lasting at least 10 μs and emits eight square-wave pulses at 40 kHz. The duration of the echo signal corresponds to the time from transmission to reception of the ultrasonic signal.

  • Operating voltage: 5 V DC
