CO2 Cuckoo Clock
Andreas Spiess published a video building a unique CO2 sensor design. He presents a case why eCO2 sensors may not always be a good idea for an environmental sensing project and builds a cuckoo clock to detect aerosols. - YouTube
IoT Twitter Listener Party Parrot
Throw a party every time someone sends you a tweet. This project uses the Twitter API v2 to query tweets and displays them as a sprite animation on a RGB LED Matrix. - Adafruit Learning System
Irrigator: Smart Sprinkler Controller
This smart sprinkler controller allows you to setup your own custom sprinkler system using a Raspbery Pi, a 4+ channel relay, and 24V AC Power Supply. If you have an existing sprinkler controller, it’s likely you can swap in this project relatively easily, utilizing the existing power supply - Github
IoT Air Quality Sensor with Adafruit IO
Breathe easy, knowing that you can track and sense the quality of the air (and environment!) around you with an IoT Air Quality Sensor. This sensor measures PM2.5 (particles that are 2.5 microns or smaller in diameter) dust concentrations, temperature and humidity - Adafruit Learning System
WaterAid is an affordable DIY IoT smart water quality monitoring device which allows scientists and authorities to identify polluted bodies of water - Hackaday.io
Smart Ping Pong LED Lamp
This LED lamp is a quick project that can be done within a day. Only a few cheap components are needed to create a nice looking ambient lamp. No programming is needed, the WLED firmware is uploaded to a microcontroller via a simple tool - Youtube
