The SparkFun MAX31855K Thermocouple Breakout is a simple 14-bit resolution, SPI-compatible, serial interface thermocouple digitizer that makes reading a wide range of temperatures possible. A thermocouple works by ...

SKU: SF-COM-13247 | Brand: SparkFun

This is the Magnetic Door Switch Set, a small reed switch assembly specifically designed to alert you when doors, drawers, or any other aperture opens. These types of switches are primarily used in home security syste...

SKU: SF-SEN-11084 | Brand: SparkFun

Life has its ups and downs, so why not measure them? The MPL3115A2 is a MEMS pressure sensor that provides Altitude data to within 30cm (with oversampling enabled). The sensor outputs are digitized by a high reso...

SKU: AF-374 | Brand: Adafruit

These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontro...

SKU: SF-SEN-11005 | Brand: SparkFun

This non-invasive current sensor (also known as a split-core current transformer) clamps around the supply line of an electrical load to measure how much current is flowing through it. The sensor acts as an inductor, ...

SKU: AF-444 | Brand: Adafruit

Add a tiny joystick to your project with this PSP thumbstick. This is a replacement component for PSP1000's, but we think they'd make for a great little joystick/thumbstick add-on for a wearable, or portable pro...
