US-100 Ultrasonic Sensor Module With Temperature

Feature:

Main technical parameters:

1, Voltage: DC5V

2, Static current: less than 2mA

3, level output: high-5V

4, level output: the end of 0V

5, Sensor angle: not more than 15 degrees

6, Detection distance: 2cm-450cm

7, High precision: up to 1mm

8, Size:20*45*15mm

The wiring method: VCC, trig (control terminals), echo (receiver), GND

Module working principle:

(1) the IO trigger ranging, to at least 10us high level signal;

(2) module automatically send eight 40KHZ of square wave, automatic testing if it has any return signals;

(3) a signal to return to, through the IO output top level, the high level of the last time is

From the launch ultrasonic returned to time. Test distance = (high level time * sound velocity (340M/S)) / 2;

Operating voltage: DC 2.4V ~ 5.5V

Quiescent Current: 2mA

Working temperature: -20 ~ +70 degrees

Output: level or UART (jumper selectable)

Detection Accuracy: 0.3cm +1%

UART mode serial port configuration

9600 baud, 1 start bit, 1 stop bit, 8 data bits, no parity, no flow control.
