Yocto-Thermocouple-C

The Yocto-Thermocouple-C device is a USB-C temperature sensor. It lets you perform via USB instant temperature measurements on two thermocouple inputs, as well as record the measures on its internal flash for later retrieval when connected again by USB. Thanks to the use of thermocouples, this tiny module can measure the temperature of liquids, small objects, food, mechanical pieces, ovens, and so on. It is very reactive to quick temperature changes (detection in 30 [ms], stable measure in 100 [ms]).

The use of thermocouples makes it easy to measure a temperature away from the module. However, if you need to measure something dozens of meters away, you can avoid to use an expensive long thermocouple by moving the thermocouple inputs further away from the USB connector: simply split the board into two parts and solder a 4-wire cable on the designated pads.

This device ships with two 1m fine-wire twisted-pair thermocouple cables type K, which can be used to measure temperatures between -75°C and 260°C (PFA insulated, measure point non-insulated). To use a wider measuring range with the device, you can use any of the more sophisticated thermocouples that you can find on a specialized shop.
