PIR sensor wiring ??
Hi
Got these sensors from Amazon https://www.amazon.com/gp/product/B016Y ... UTF8&psc=1
From my readings in forum I understand I need to setup ESP Easy as input switch for it but I have two questions:
-> what is wiring of such sensors ? have found nothing reliable on Internet
->_some experiences with these same sensors ? as after reading feedback from PIR users in forum looks like a lot of these sensors are really bad...
Thanks
Vincèn

Hello,
the only info i have found is this picture:
.
To be honest, i'm not sure if it is correct or not.
I did not test these sensors yet so i can't say if they are really reliable or not.
I've used a HC-SR05 (the bigger one) for a server room monitoring, and it works - for me.
I know it does not for others.

Re: PIR sensor wiring ??
Those shoudl be AS312 PIR (you can check this removing the white plastic and look at the text engraved on the sensor).
then the connection is the one reported by Shardan but please check if the PIR has a voltage regulator as it's supposed to work at 3.3V and not 5V!!
See below the schematic I've found which matches 100% the 5 units I've.

Re: PIR sensor wiring ??
Hello all,
I've just checked the given wiring from my post above with a quick breadboard circuit...
Approved, the pinout is correct.

Removed completely the white plastic around the sensor but unhappy nothing engraved or labelled on it
I have checked mine against your schema and I confirm it's wiring on mine so it looks like it has a voltage regulator ! so I guess I can power supply it with the 5V I have on my ESP board no ? and plug signal output to a Digital input and I should be ok with wiring
Thanks for help

Re: PIR sensor wiring ??
Hello,
i've found different data about the Mini PIR.
Most say 2,7...12 V. I doubt about 2,7V as it is lower then the 3,3V output from the small voltage regulator
and would give "bad karma", say instabilities.
Anyways, 5V is safe and should work stable - at least it did for some hours on my breadboard.

Shardan.

Re: PIR sensor wiring ??
For the Sensor
https://unusualelectronics.co.uk/downlo ... 6834e7a283
Shows Vdd Type 3V, Min 2.7, Max 3.3V
Maximum rating 3.6V
For the Module
If you see a chip marked 7533-1 on your module then it has a 3V voltage regulator.
Power supply needs to be higher then 3V (voltage drop is 100mV@1mA) and lower then 24V.
Hope this helps

30+ ESP units for production and test. Ranging from control of heating equipment, flow sensing, floor temp sensing, energy calculation, floor thermostat, water usage, to an interactive "fun box" for my grandson. Mainly Wemos D1.
Re: PIR sensor wiring ??
I confirm that sensor works fine powered at 3.3V by the ESP board Works like a charm for me
