You'll be automating an adorable paper maché house. The small size of this build lets us explore wiring, user interaction, and firmware deployment without having to get a ladder out.

After building this project, you can re-purpose this project for your home or apartment. We've specifically selected components and sensors which are common in real-world IoT projects. You can also go further with this project, adding sensors to monitor different rooms in your house.

Parts

This tutorial uses the ESP32 Feather as the microcontroller brains, it can use both secure WiFi and Bluetooth LE as transports.

To build the smart home's hub, you'll use a Quad 2x2 FeatherWing Kit. This kit contains four identical sets of headers for Feathers/FeatherWings and two prototyping areas.

For inputs, you'll use the Analog Devices Featherwing to obtain precision temperature readings and the Bosch BME680 to obtain humidity, barometric pressure, and air quality. 

We’ll add a magnetic door sensor to detect when someone opens a door or window and add a buzzer to make a a loud 2KHz BEEEEEEEEEP when someone opens the door.

For outputs you'll use a Non-Latching Mini Relay FeatherWing to control a DC motor - that’s our way of simulating an HVAC unit that turns on when it gets too hot or too cold.

You'll also connect some LED lights to a GPIO pin on the HUZZAH32, so you can turn on or off the lights from the DK IoT Mobile App, or when someone opens the door.

You'll need a few JST-PH cables for this build. These cables will allow you to easily remove sensors connected to the IoT Home Hub from the enclosure with a nice click.
