Connection mode: 1.VCC 2.trig(T) 3. Echo (R) 4.GND Usage method: Power supply module with 5V, the output will be 5V while obstacle in range, or 0V otherwise. The output pin of this module is used as switching output when switching the anti-theft module, and without the feet when switching modules. Note: The module should be inserted into the circuit before power supply, which avoids producing high level of misoperation; if not, then operate again.
Module working principle: 1. Adopt IO trigger providing a sequence of at least 10us high level signal. 2. The module automatically sends eight 40khz square waves and automatically detects whether you receive the return pulse signal. 3. If there are signals returning, through the high level output and the high level time Continuing is the time of that of the ultrasonic transmission to receive. Test distance = (High level time * sound speed (340M/S) / 2. Note: This module is not suitable to connect with power supply, if you need to connect this module with electronic power supply, then let the GND terminal of this module be connected first, otherwise it will affect the normal work of the module
