The footprint is also lower when compared to infrared motion sensors.

Make a Microwave Radar Motion Sensor for Smart Home

Motion sensors can also help you save energy by automating light switches.

installed in your home or office.

There are manyways to use motion sensors.

flash tasmota firmware on esp 01

Since the radar sensor has a built-in 3.3V regulator, we dont need to use the AMS1117-3.3V regulator.

If motion is detected, the output will display the status.

The possibilities are endless.

send wifi details to the esp 01 device

get the ip address of the device to load tasmota web ui

configure motion sensor in tasmota web ui

connect esp 01 to microwave radar sensor and micro usb module

assemble parts in 3d printed case

add home assistant mqtt details

give motion sensor a name

select motion sensor in home assistant to create automation
