US-100 ultrasonic ranging module can achieve a non-contact distance measurement function 2CM ~ 4.5M, with 2.4 to 4.5 wide voltage input range. Stable and reliable.

 

2, the main technical parameters:

 

Use a voltage:. DC5V

. B Static current: less than 2mA

c level output: 5V high

. D level output: the end of 0V

. E Sensor angle: not more than 15 degrees

. F detection range: 2cm-450cm

g precision: up to 1mm

 

3. Wiring:

 

From left to right are numbered VCC, trig (control side), echo (receiving end), GND (ground)

 

4. Use Method:

 

A control port more than send a 10US high, you can wait for the high output at the receiving port. There are output on a timer can start counting, when this port goes low timer value can be read this when it's time for this distance, before calculating the distance. this constant cycle of measurement, you can reach the value of the mobile measurement ~ ~

 

5. The module works:

 

(1) The IO trigger ranging to at least 10us high signal; and

 

(2) module automatically sends eight 40khz square wave and automatically detect whether a signal return;

 

(3) the signal returned by a high IO output, high duration is Ultrasonic time from launch to return. Measure

 

Test distance = (high level time * sound velocity (340M / S)) / 2;


This module provides a full set of ranging procedure: C51, PIC18F877, ultrasonic LCD1602 display,

 

Ultrasonic LCD12864 display, digital display, serial display, ranging reference program.
