2020 HC-SR04 ultrasonic sensor / ultrasonic range / ultrasonic module / 3.3V-5V with only one chip
Specificatii:
HC-SR04 Ultrasonic Sensor Distance Module: using IO trigger for at least 10us high level signal
This module has stable performance and accurate measurement distance.
Detection distance: 0.78~196 in/ (2cm~500cm); High precision: up to 0.12 in/(0.3 cm); Detection angle: <15 °.
This module is fully Compatible with GH-311 anti-theft module.
HC-SR04 Arduino ultrasonic sensor can send eight 40 kHz and detect whether there is any pulse signal back.If it back, a high level signal will be outputed by IO, and the duration of the signal is the time from sending ultrasonic to returning.
