ESP8266 multisensor
How to make an ESP8266 based multisensor in six steps?
1. Buy this:
2. Make your plan:
3. Scrap unnecesarry things:
4. Install parts according the Plan
5. Put back the cover
6. And do not forget to install ESPEasy... You are ready!

I've made an Instructable about it:

Re: ESP8266 multisensor
Did you shield the radar module?
Otherwise it is also detecting people at the other side of the wall you mount this to.

Re: ESP8266 multisensor
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.
Re: ESP8266 multisensor
Don't place metal too close to the radar sensor, or else it will not start the oscillator.
Re: ESP8266 multisensor
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.
Thanks.
Re: ESP8266 multisensor
I have ordered another smaller night light too. Challange will be to fit everything in the case but it has mains power.

I am curious how it looks like inside. Could you please post some pictures about it when it arrives?
Re: ESP8266 multisensor
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:

Re: ESP8266 multisensor
Wow! Internal circuits are not so complicated.. but as i see there are enough space for an 5v power supply and an esp8266.
Re: ESP8266 multisensor
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
Thanks
Re: ESP8266 multisensor
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:

Re: ESP8266 multisensor
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.

Re: ESP8266 multisensor
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.
Thanks.
Re: ESP8266 multisensor
Here is another interesting clock device which could use neoppixel leds if reverse engineered by someone and processor is replaced with ESP8266.The processor look like 8051 based.If ESP8266 is used it opens up possibilities to do other things like weather station etc.
