RCW-0001 (Micro Ultrasonic Range Distance Measuring Module)
RCW-0001 Micro Ultrasonic range Distance Measuring module robot electronics 3.3-5v 1cm Ultra-small blind Ultrasonic Sensor
Description:
RCW-0001 Micro Ultrasonic range Distance Measuring module robot electronics 3.3-5v 1cm Ultra-small blind Ultrasonic Sensor. External control software is fully compatible with the HC-SR04, the use of specialized mediation chip, the smallest blind 1cm Ultra-small blind, ultra mini volume
Below are the main technical parameters;
1: Voltage: DC 3.3-5V
2: Induction angle: not more than 15 degrees
3: detection distance range: 1cm-450cm
Board wiring: VCC, trig (control side), echo (receiving end), out (empty feet), GND
Note: To avoid high level, better to insert module to circuit board before powering, if has high level, restart power to solve it.
How Module works:
(1) The IO trigger ranging, give the high level of the signal at least 10uSec;
(2) Module automatically sends eight bits of 40khz square wave and automatically detect whether a signal return or not
(3) There is a signal to return, through the IO high level output, the time of high level duration is Ultrasonic time which is calculated from launch to return.
Test distance = ( time of high level * speed of sound (340M / S)) / 2
Application Note:
1. This module should be connected with power after connecting GND pin. Otherwise it will affect the module.
2. The object’ area which be tested is not less than 0.5m2, and as flat as possible, otherwise it will affect the test results.
3. If the measured test surface is irregular or distant objects, can be used to correct for multiple measurements.
