US-100 Ultrasonic Sensor Module DC 2.4V - 5V With Temperature Compensation Range Distance 450cm For Arduino
This module is improved, the module itself has temperature compensation, the accuracy of the highest module now clean out treasure, absolute stable, economical, practical.
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.
1. the main technical parameters:
1) the use of voltage: DC5V
2) the static current: less than 2 mA
3) level output: high 5 V
4) level output: bottom 0 V
5) induction Angle: no more than 15 degrees
6) detection range: 2 cm-450 cm
7) high precision: up to 1 mm
2. The wiring way:
VCC, trig (control terminals), echo (receiver), GND
3. 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.
4. The module works:
(1) the IO trigger ranging, to at least 10 us high level signal;
(2) module automatically send eight 40 KHZ of square wave, automatic testing if it has any signals return;
(3) a signal to return to, through the IO output top level, the duration of the high level is from the launch ultrasonic returned to time. Test distance = (high level time * sound velocity (340 M/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.

This module 1, stable performance, measure distance accurate:
Can SRF05 and abroad, such as SRF02 ultrasonic ranging module comparable. Module high precision, blind area (2 cm) super close, stable is the product range to the market success of powerful according to!
6.Method of use:
A control mouth hair a 10 US above the high level, can wait for high level output receiver mouth. A has an output can open timer time, when the mouth into a low power can be read at ordinary times timer values, where you for the ranging time, can calculate the distance. This will continue the cycle, can reach you move measurement value.
