WHAT'S NEW TOP SELLERS QWIIC TEENSY REDBOARDS THING+ TUTORIALS

The SparkFun STCC4/SHT40 Qwiic CO2 Sensor is a simple indoor air quality breakout that primarily measures CO2 concentration, as well as temperature and relative humidity - all over I2C. Specifically, the board features a pair of Sensirion sensors isolated in their own section: the STCC4 CO2 sensor and the SHT40 digital temperature and humidity sensor. These two sensors work together to output precise and environmentally compensated CO2 readings without any complicated wiring.

Time to Measure Actual CO2

The SparkFun Environmental Combo Breakout takes care of all your atmospheric and indoor air quality sensing needs by combining two industry-leading ICs on a single board: the ScioSense ENS160 and the Bosch Sensortec BME280! Whether you are building a smart HVAC system, a weather station, or an indoor air quality monitor, this unique two-in-one breakout provides a comprehensive picture of the air you breathe.

The Environmental Wombo-Combo

This paper-thin, adhesive UHF RFID tag has been designed for versatility and high performance. Measuring just 70mm x 20mm, it's small enough to stick to almost any object while still providing reliable wireless identification. Each tag uses the H9 RFID chip, which offers significant upgrades in speed, range, and memory over the standard H3 generation.

The Perfect Tag for UHF RFID

Of course, you'll need something to scan your new UFH RFID tags! The SparkFun Simultaneous RFID Reader makes this powerful UHF technology accessible and affordable for everyone. Built around the high-performance M7E Hecto module from JADAK, this board lets you easily read and write to standard EPCglobal Gen 2 tags (the most common passive UHF tags in the world). Just don't forget your antenna!

Hubble Network recently opened public access to its satellite network for IoT devices, making it possible to send data through its satellite network using Bluetooth-enabled hardware. Even better, you don't necessarily need specialized satellite hardware to get started. In this week's video, we connect a SparkFun ESP32-C6 Thing Plus to the Hubble Network and walk through the process from setup to sending data. To celebrate their new launch, Hubble is offering a free 45-day trial for both the Terrestrial and Satellite Networks!
