Just a comment.
On several tutorials, it’s written that it’s necessary to connect GPIO16 to Reset pin. But take care, there are several kind of ESP8266 and on mine (12F), it’ necessary to connect RST with GPIO16 (SCLK), not with WAKE pin. And, on board, the numbers written are not those with GPIO numbers.

I had problems waking the D1 Mini after deepsleep. It sent the usual gibberish on serial and then stopped. Solution:
station.active(False)
sleep(5)
deep_sleep(10000)

Hi.
To wake up your boards from deep sleep using the PIR motion sensor, take a look at deep sleep with external wake up.

I am working on ESP8266 for home automation I am trying to connect ESP 8266 with PIR sensor.Already have written the code for the same including Wifi Manager.

Planning to intorduce Deep sleep of Node mCu and wake only when theres an input from PIR sensor. Is there any code for the same.

Thanks in Advance

As far as I know, this sensor uses heating of active measuring surface. This heating is probably dependent on current consumed from power supply. Your GPIO pin propbably does not give you sufficient current. Better solution can be to use some MOSFET controlled by GPIO to attach your directly to 5V power supply. Anyway, this type os sensor probably will not be the best chice for battery powered device due to its relatively large consumption.

Thanks for the prompt response.

Thanks,

All I had to do is read all the instructions. Thanks for pointing this out to me

Hi.
Don’t forget that to use deep sleep with the ESP8266, after uploading the code, you need to connect GPIO16 (D0) to the RST pin so that the ESP8266 can wake itself up.

Sara
