# Adafruit IO Home: Lights and Temperature ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/060/145/medium800thumb/raspberry_pi_hero-houseseries-1.jpg?1535390262) Interested in making your house a bit smarter?  Why not start _small _by building a  **Cardboard** **Smart** **Home**! Adafruit IO Home is a series of learning guides covering all aspects of a smart house: from temperature monitoring to an intelligent home security system.  _Want to scale up from the cardboard home to a real home?_  We've selected real-world components, sensors, and hardware which can also be installed in your home, office or laboratory! This is the first guide in the series, and there's more to come! ## **Parts** ### Temperature and Humidity If you want to install a temperature and humidity sensor in your home, you're in luck. [There's a plethora ** ** of these dual-use-type sensors available on the Adafruit Shop](https://www.adafruit.com/category/56) to select from. We're going to use the **Si7021** , a digital temperature and humidity sensor which is less expensive than the popular [DHTxx sensors](https://www.adafruit.com/?q=dht). In addition to being inexpensive, it uses an I2C interface, freeing up digital pins on our Feather HUZZAH microcontroller for other things - like pretty lights and loud buzzers.  ### Adafruit Si7021 Temperature & Humidity Sensor Breakout Board [Adafruit Si7021 Temperature & Humidity Sensor Breakout Board](https://www.adafruit.com/product/3251) It's summer and you're sweating and your hair's all frizzy and all you really want to know is why the weatherman said this morning that today's relative humidity would max out at a perfectly reasonable 42% when it feels more like 77%.

For lighting inside the house, we'll be using a **NeoPixel Jewel** comprised of seven NeoPixels on a round PCB. This light will serve as the lighting inside the house. As a bonus - it looks like a chandelier or a lamp when it's wired using solid-core wire. ### NeoPixel Jewel - 7 x 5050 RGB LED with Integrated Drivers [NeoPixel Jewel - 7 x 5050 RGB LED with Integrated Drivers](https://www.adafruit.com/product/2226) Be the belle of the ball with the NeoPixel Jewel!  We fit seven of our tiny 5050 (5mm x 5mm) smart RGB LEDs onto a beautiful, round PCB with mounting holes and a chainable design to create what we think is our most elegant (and evening-wear appropriate) NeoPixel board...

This strip is thin enough to wrap around the roof of the house and you can cut it to-length.  In addition to serving an aesthetic purpose, the outdoor lighting will also be used in later guides which will involve home security.  ### Adafruit Mini Skinny NeoPixel Digital RGB LED Strip - 60 LED/m [Adafruit Mini Skinny NeoPixel Digital RGB LED Strip - 60 LED/m](https://www.adafruit.com/product/2964) So thin.

This board is used by most of our Adafruit IO guides since the ESP8266 is a highly popular and versatile IoT platform.  This guide is also CircuitPython-compatible. You can use a Raspberry Pi with the IO House series. ### Adafruit Feather HUZZAH with ESP8266 - Loose Headers [Adafruit Feather HUZZAH with ESP8266 - Loose Headers](https://www.adafruit.com/product/2821) Feather is the new development board from Adafruit, and like its namesake, it is thin, light, and lets you fly!
