Pusher
...Back to Projects:
The Pusher Board is an IoT project that does one thing - it pushes you a notification triggered by a digital input. Well, it's much more than that, but this is the inspiration. I wanted to design a WiFi board that essentially sleeps most of its life, but when that door switch, flood sensor, motion sensor, etc.. gets triggered, I just want a notification immediately on my phone. And that's about it... a perfect IoT device in the background doing its job.
Version 1
Very first prototype board
- Mostly through hole components for easy testing and assembly
- ESP8266 based (ESP-12S module)
- Wake on regular timer interval - set for 1hr during my testing.
- Wake on Digital Input - Normally Closed type contact, so works nicely with door sensors.
- Tested sleep current <1uA that's years and years of battery life.
- Max Battery Voltage is ~4.2VDC, so designed to be used with standard Lithium Batteries.
- Note: this board does require re-work in order to exercise all of the functionality. Please watch assembly videos below for detailed information
