Did you shield the radar module?
Otherwise it is also detecting people at the other side of the wall you mount this to.

Nope, however i planned to use some tin foil beneath it, but eventually it is not needed. (at least for me)
Motion sensor is combined, so if the radar sensor is seeing from the other side of the wall, the infrared sensor sees nothing = no movement detected as i using AND logic.

Don't place metal too close to the radar sensor, or else it will not start the oscillator.

Nice find @enesbcs .I am working on a standard multisensor hardware using esp8266,bme280,IR receiver,IR transmitter,APDS-9960,neopixel,rcwl sensor and pir sensor. I will try to fit all on this case.

Thanks.

I have ordered another smaller night light too. Challange will be to fit everything in the case but it has mains power.

Nice!
I am curious how it looks like inside. :) Could you please post some pictures about it when it arrives?

Yes I will do it. I also want to use the one linked below. It is metal so more srurdy but little expensive.

Another one I am going to modify to remove IR led and receiver and put more powerful ir transmitter & receiver and with APDS-9960 I want to make torchlight plus DIY remote control:

Wow! Internal circuits are not so complicated.. but as i see there are enough space for an 5v power supply and an esp8266. :)

As you can see box is almost empty so there is plenty of space.It uses classic capacitor dropper circuit to convert AC to DC.I measured output of bridge rectifier between 2.45 to 2.60 Volts DC. ESP8266 datasheet says device need minimum of 2.5 volts DC.If we are lucky we can use output of bridge rectifier with smoothing capacitor to run our device without any extra power supply.I will try running it to test.

Thanks

I think built in ac-dc converter is not suitable for esp8266's high current requirement. I will be using this instead to power esp8266:

For battery powered sensor device this single rechargeable battery is suitable for esp8266 without any power regulator:

Those Hi-Link blocks are very well suitable to power an ESP.
You can get them in 5V and 3v3 versions.
Just make sure you have enough isolation when working with mains.
Also make sure you can get rid of the heat.

They are little safer too as they come with a casing around it but they are bit expensive. If good care taken installing the open modules without casing it can be used as they cost lot less.

Thanks.
