Specificatii:

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

 

1, 1cm Ultra-small blind, ultra mini volume !

 

2. 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.    

 

3, Module works:    

 

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

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

(3) there is a signal to return, through the IO output a high level, the time of high level duration is Ultrasonic time from launch to return.    

(4) 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.
