DC5V UART Integrated Waterproof Ultrasonic Sensor Car use parking distance measuring sensor

Features of Ultrasonic Level Sensor:

1. Small size, easy to use

2. Low voltage, low power consumption

3. High accuracy

4. Strong anti-jamming

5. Integrated with wire enclosed waterproof probe, suitable for wet, harsh measurement occasions

The basic working principle:

(1) Using IOTRIGTrigger ranging, to at least 10us high-level signal;

(2) The module automatically sends8A 40khz square wave, automatically detect whether there is signal return;

(3) There is a signal return via IOECHOOutput oneAHigh, high duration is the time from the launch of the ultrasound to the return.Test distance = (high time * sound speed (340M / S)) / 2;

The use of this module is simple, a control mouth made a 10US above the high level, you can wait for the reception of high-level output. An output can be opened timer time, when the mouth becomes low when you can read The value of the timer, this time for the distance of time, can calculate the distance. Such a continuous cycle measurement, which can be measured to achieve the value of your move.
