This security alarm circuit using RCWL-0516 microwave radar motion sensor will detect any moving thing in the restricted area and turn ON an alarm sound. The RCWL-0516 is basically an advanced motion sensor using microwave radar signals. I have already discussed the working of RCWL-0516 elaborately, which you can read for more details.

How to Make a GHz Microwave Radar Security Alarm Circuit
In this post I have explained a GHz microwave radar security alarm circuit which is designed to detect an intruder within the critical zone only while it’s moving, static objects produce no effect for the sensor. Using Doppler Sensor KMY24 In the previous article I have explained about a microwave Doppler radar sensor module KMY […]
