IoT Projects

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

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

Threat modeling your IoT Projects

While building a pollution-monitor, @dcuthbert wrote an excellent twitter thread about threat modeling their IoT sensor - Twitter

TP-Link KL50 Smart Bulb Teardown

Tearing down an inexpensive LED filament WiFi bulb - ElectroBob

NEW IoT Hardware: Adafruit Metro ESP32-S2

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

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.

Adafruit IO Wippersnapper

We’re working on a new way for you to interact with Adafruit IO called Wippersnapper. While Wippersnapper is not public (yet!), we’ll be sharing details, features, development progress and updates every Wednesday on the Adafruit Blog as we work on this new service.

Adafruit IO Stats

Adafruit IO has 353,825 total users! Here are the interesting stats from the last 30 days:

• Total Feeds: 562,833 (and counting!).
• There are over 201,06 feeds online as of time of writing (October 29, 2020).
• There are an average of 7,500+ MQTT connections active 24/7.

We don’t have investors and we’re not going to sell your data. When you sign up for Adafruit IO+, you’re supporting the same Adafruit Industries whose hardware and software you already know and love! You help make sure we’re not going anywhere by letting us know we’re on the right track.

Support Adafruit

Here at Adafruit, we sell all of these amazing components, but we couldn’t find a good way to interact with them over the Internet. So, we decided to create our own IoT platform, and that’s Adafruit IO. It’s built from the ground up to be easy to use and platform agnostic (connect any development board or device!). For those who want to get a project off the ground without programming - Adafruit IO offers a No-Code interface for building IoT electronics projects using WipperSnapper, our open-source IoT firmware. Support Adafruit’s open-source development by subscribing to Adafruit IO Plus, the upgraded, all-systems-go version of the Adafruit IO service.
