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;
