This tutorial will show you how to take soil moisture readings and then display those readings on an OLED as a happy, meh, or sad face, depending on how wet or dry the soil is.

For this project I’m going to be using one of our newer, smaller magnetometer boards to control a pair of servos, and then toss out some ideas to upgrade to a much bigger, cooler project.

In this tutorial, we'll show you how to use the SparkFun Tristimulus Color Sensor - OPT4048DTSR (Qwiic) to detect and classify colors based on their CIE XYZ color space values.

Looking to add some motion detection to a project you are working on? The SparkFun PIR Breakout - 170uA (EKMC4607112K) and SparkFun PIR Breakout - 1uA (EKMB1107112) might be just the thing!

Introducing the SparkFun MicroMod ESP32 Processor Board! This bad boy pops an M.2 connector onto the ESP32 so you can take advantage of all that lovely ESP32 power with any of our MicroMod carrier boards.

These breakouts eliminate nearly all the inconvenience of using buttons by converting everything to an easy-to-use I2C connection using the Qwiic Interface.

The SparkFun Power Delivery Board takes advantage of the power delivery standard with the use of a standalone controller from STMicroelectronics, the STUSB4500.

This article will compare a few of the more popular ones we carry.‎

SparkFun has 2 new thermocouple amplifier boards - the SparkFun Qwiic Thermocouple - PCC and the SparkFun Qwiic Thermocouple - Screw Terminals.

The SparkFun Temperature Sensor - STTS22H (Qwiic) and the SparkFun Micro Temperature Sensor - STTS22H (Qwiic) are Qwiic enabled breakout boards based on the ultralow-power, high-accuracy, digital temperature sensor STTS22H from ST Microelectronics.

The SparkFun Air Quality Sensor - SGP40 (Qwiic) is a robust metal oxide (MOx) based indoor air-‎quality measurement tool using the SGP40 gas sensor from Sensirion.
