Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference, as well as calculations to handle any non-linearities. For a long time we've suggested our MAX31855K breakout, which works great but is only for K-type thermocouples. Now we're happy to offer a great new thermocouple amplifier/converter that can handle just about any type of thermocouple, and even has the ability to give you notification when the temperature goes out of range, or a fault occurs. Very fancy! This converter communicates over 4-wire SPI and can interface with any K, J, N, R, S, T, E, or B type thermocouple
The LIS3DH is a very popular low power triple-axis accelerometer. It's low-cost, but has just about every 'extra' you'd want in an accelerometer: Triple axis sensing, ±2g/±4g/±8g/±16g selectable scaling, both I2C and SPI interfaces, tap, double-tap, orientation & freefall detection, as well as 3 additional ADC inputs you can read over I2C
Give your next sensor project a nose for gasses with the Adafruit MiCS-5524 Gas Sensor Breakout. This breakout makes it easy to use this nice sensor from SGX Sensortech. The MiCS-5524 is a robust MEMS sensor for indoor carbon monoxide and natural gas leakage detection, it's suitable also for indoor air quality monitoring; breath checker and early fire detection.
Worn on a lanyard or clipped to a pocket or pack, this adorable camera snaps a photo every few seconds. Slide the SD card into your computer to review the day’s activities or merge all the images into a timelapse animation. Powered by the diminutive and affordable Raspberry Pi Zero, this DIY project is eminently configurable and customizable!
Give your Feather a sense of place, with an Ultimate GPS FeatherWing. This FeatherWing plugs right into your Feather board and gives it a precise, sensitive, and low power GPS module for location identifcation anywhere in the world. As a bonus, the GPS can also keep track of time once it is synced with the satellites.
