1. EIKS #ad
Excelity 3pcs Ultrasonic Module HC-SR04 Distance Sensor with 3pcs Mounting Bracket #adEIKS #ad
- Package included 3pcs hc-sr04 distance measurement module & 3pcs mounting bracket for installation. Working principle using io trigger for at least 10us high level signal, when triggered it sends out a series of 40KHz ultrasonic pulses and receives echo from an object, the duration of the signal is the time from sending ultrasonic to returning.
The distance = duration time * sound velocity 340M/S / 2. Universal compatibility built in standard interface that can be controlled directly by microcontroller，such as 8051, AVR. Functional parameter effectual angle:
