IoT Projects

CO2 Cuckoo Clock

co2clock

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

twitteriot

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

irrigator

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

aqi

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

NEW IoT Hardware: Adafruit Metro ESP32-S2

feathers2

The first Adafruit board using the new ESP32-S2 240MHz Tensilica processor is out! This board is perfect for adding low-cost WiFi to your CircuitPython (with Native USB) or Arduino projects.

Check out the ESP32S2 in the Adafruit Shop

NEW IoT Hardware: FeatherS2

metros2

The full-featured ESP32-S2 based development board in a Feather format from Unexpected Maker. The FeatherS2 is a power house, fully souped up with 16 MB of Flash memory (for firmware and file storage) and 8 MB of QSPI-based external PSRAM so you can have massive storage buffers.
