| − | 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.

| − | * Simple IoT development board that was designed to trigger "Push Notifications" on a smart phone/tablet based on a trigger event.
| |
| − | * Unique low-power front-end to enable sub 1uA sleep current - uses a pulse to trigger wake-up, so even if door/window/etc is opened, the same ultra low currents can be maintained. Compare to standard pull-up/down resistor based digital input designs with significantly higher leakage current.
| |
| − | * The board will wake itself up once an hour to check the battery voltage - if running low, a push notification is sent to warn the user. This timer can be used to check other things as well - temperature changes, accelerometers, or other environmental sensors.
| |
| − | * Based on ESP8266 WiFi Module (ESP-12S) - all source code is available for download and developed in the popular Arduino IDE.
| |
| − | * Battery Input can be any Lithium Polymer 3.7V - standard micro JST connector jack is used (please double check polarity),any of [https://www.adafruit.com/category/574 these] would work nicely.
| |
| − | * Sensor input to trigger the "Wake Up" is a simple passive switch. Typically a standard magnetic door/window switch is used and the board can be configured to wake on the "opening" (Normally Closed) or "closure" (Normally Open) of the contact. Solder jumpers set this - Normally Closed is Default, so standard door/window switches wake the board up when opened.
| |
| − | * Battery Charging On-Board via MicroUSB - set for 4.2V at 500mA. 5V input pads broken out for energy harvesting experimentation.
| |
| − | * Dimensions only 0.8" x 1.6 " (20.32mm x 40.64mm)

| − | == Pusher Board Base Firmware ==
| |
| − | | |
| − | Note! the board is preloaded with the base firmware out-of-the-box, but if you want to develop/modify your own firmware, this section will go through the steps for getting the base code to compile.
| |
| − | | |
| − | Base Firmware Developed on Arduino V1.8.3 - can download [https://www.arduino.cc/en/Main/OldSoftwareReleases#previous here]
| |
| − | | |
| − | Then you'll find that the code does not compile and that's because you need several libraries and the board manager installed. Here's what you need:
| |
| − | | |
| − | First, go to File>>Preferences and add this URL to to the "Additional Boards Manager URL". http://arduino.esp8266.com/versions/2.3.0/package_esp8266com_index.json
| |
| − | | |
| − | [[File:BoardManagerURL.png|400px]]
| |
| − | | |
| − | Now, the ESP8266 boards will be available for installation. Go to Tools>>Board>>Boards Manager... Search for ESP8266, and go ahead and click install. Note, I'm using v2.3.0
| |
| − | | |
| − | [[File:ESP8266Install.png|400px]]
| |
| − | | |
| − | After the boards are installed, you can select any of the ESP8266 boards out there from the Board Selection. For the Pusher board, I have been using the Adafruit Huzzah, here are my settings. Note that I always upload as fast as possible:
| |
| − | | |
| − | [[File:Pusher Huzzah Settings.png|400px]]
| |
| − | | |
| − | Next, you'll need to install the specific Arduino Libraries I'm using in the base code. The first one is is the [https://github.com/tzapu/WiFiManager WiFi Manager by tzapu] - the easiest way to install the library is to go to Sketch>>Include Library>>Manage Libraries. Then type in WIFImanager. Go ahead and install the library - note I'm using v0.12.0
| |
| − | | |
| − | [[File:WiFiManager.png|400px]]
| |
| − | | |
| − | Do the same for the [http://arduinojson.org/ Arduino JSON library by Benoit Blanchon] - can just search for JSON. I'm using v5.11.1
| |
| − | | |
| − | [[File:ArduinoJSON.png|400px]]
| |
| − | | |
| − | Then that should be it - the other libraries are automatically installed with the ESP8266 board manager.
| |
| − | | |
| − | See the "Testing and Programming" section below for information on loading the code over a wired USB-Serial connection. The other option is to load code wirelessly "OTA - Over the Air". In the "Pusher Board Operation" section this is shown.

| − | 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.
