ESP8266_PIRv2

ESP8266 Huzzah Deep Sleep Mode PIR Motion Alarm using IFTTT

Version 2 – This version changes the ESP8266 to use Deep Sleep mode to significantly save battery power. Requires extra hardware. See original version for simpler hardware (and shorter battery life).

This version is only needed if you wish to run the unit using AA batteries. After 4 months and hundreds of triggers, still running strong on the same set of batteries.

We just installed a Cat Door in our garage and I wanted to see how many times per day (actually night) our cat went in and out the door. We could tell the cat was using the door as we would find it outside sometimes and inside sometimes. So, breaking out my parts box, I found a PIR motion sensor and ESP8266.

I used the Adafruit HUZZAH ESP8266 as it has a regulator for powering the 3.3v ESP as well as good tutorials for initially getting it set up. I also used the Arduino IDE with the ESP8266 library, since I was already quite familiar with using it with the Huzzah ESP8266. I decided to interface this to IFTTT (www.ifttt.com) to trigger any number of types of events. Initially, just an email each time motion was detected.

esp8266_pirv2's Issues

Rebooting too fast...

I think I have this implemented correctly. So thank you for that! Looks to be working great... except for one issue.

It seems like if it continues to detect motion, it keeps rebooting over and over usually before it makes it all the way through my code (a little different than what you have)... which I think is correct.

Any ideas on how you could stop this until the code is fully executed?

"connection failed"

Hello sir,
I've checked and rechecked the sketch, editing and rechecking the ssl fingerprint many times.
I get a "connection failed" message every time regardless of what I try.
Any ideas?

Battery life time

Hi,

is there a final comment how long the batteries lasts?

PIR Pin not specified

In your v2 code you haven't specified the PIR sensor pin, how ESP will detect the motion?

type transistor for deep-sleep

Hi,

Do you know if your setup will also work when using a 2N3904 TO-92 NPN transistor to connect between ESP and PIR module?

Wiring for regular ESP8266

I suspect that this will only work with a ESP8266 Huzzah, right? The regular ESP8266 modules that I have all freeze when RST is held low, and come back to life again when RST rises again. With the wiring that you propose, a regular ESP8266 is disabled when motion is detected, and when it comes back to life motion is already gone because that's when the PIR outputs a low signal.
