Sensors

OpenScale allows you to have a permanent scale for industrial and biological applications. Learn how to use the OpenScale board to read and configure load cells.

Let's have some fun with LEDs! We'll explore LEDs once again with the SparkFun RedBoard Qwiic, making cool effects, and putting those effects to work using a sensor.

The Panasonic GRID-Eye (AMG88xx) 8x8 thermopile array serves as a functional low-resolution infrared camera. This means you have a square array of 64 pixels each capable of independent temperature detection. It’s like having thermal camera (or Predator’s vision), just in really low resolution.

The VEML6030 is a high accuracy ambient light sensor with 16-bit resolution. This I2C sensor can detect light similar to the human eye response. Start detecting light levels in your environment!

How to use and customize the SparkFun OpenPIR motion sensor.

Learn how to connect the RedBot Line-Following Sensor Bar to an Arduino-type microcontroller. Use the example sketches to read data from the bar, and try out a simple line-following algorithm.

Learn how to measure the current consumption of your project using the ACS723 Current Sensor.

The SparkFun Inventor's Kit (SIK) Experiment Guide contains all of the information needed to build all five projects, encompassing 16 circuits, in the latest version of the kit, v4.0a.

How to use and re-program the 9DoF Razor IMU M0, a combination of ATSAMD21 ARM Cortex-M0 microprocessor and MPU-9250 9DoF-in-a-chip.

Learn how to use the SparkFun Touch Potentiometer to control lighting, volume or other inputs in your daily life.

How to hook a force-sensitive resistor up to an Arduino to measure pressure variances.

Equip your Arduino project with a sliding soft potentiometer to monitor position or adding linear control to your project.

An overview of the flex sensor - a bendable variable resistor. Plus, example circuits and Arduino code to get you started!

Here are a few tips in using the PicoBoard with Scratch v1.4. The PicoBoard allows us to write Scratch programs that interact with a variety of sensors on the PicoBoard. These sensors include: sound, light, a slider, a push button, and 4 external sensors (A, B, C, and D).

In this tutorial, we will learn about how to create an interactive theatrical prop for a performance by 3D printing a translucent diamond prop using a non-addressable RGB LED strip and AT42QT1011 capacitive touch sensing.

The Melexis MLX90640 contains a 32x24 array of thermopile sensors creating, in essence, a low resolution thermal imaging camera. In this guide, we’ll go over how to connect your Qwiic Infrared Array with MLX90640 and get it communicating with Processing to produce a nice thermal image.

Drum machines and keyboards have been the standard for making digital music, but how do you make electronic music if you're trained to play the trombone? One of our Hackers in Residence, Carlos Mello, took it upon himself to find a solution to that very question.

Are you worried about the looming clouds in the distance, how far away is that storm exactly? Add lightning detection with the AS3935 to your next weather station or your next bike ride!

Getting started with the MPL3115A2 Pressure Sensor.

The Single Supply Logic Converter allows you to bi-directionally translate signals from a 5V or 3.3V microcontroller without the need for a second power supply! The board provides an output for both 5V and 3.3V to power your sensors. It is equipped with a PTH resistor footprint for the option to adjust the voltage regulator on the low side of the TXB0104 for 2.5V or 1.8V devices.

Learn how to build a remote water level sensor for a water storage tank and how to automate a pump based off the readings!

Figure out how magnetic fields are oriented, all without having to solder a thing.

A basic guide to get started with the LSM303C 6 Degrees of Freedom Breakout.

Learn how to use the simple SparkFun AT42QT1010 and AT42QT1011 capacitive touch breakout boards.
