The Yocto-Thermocouple device is a USB temperature sensor. It will let you perform via USB instant temperature measurements on two thermocouple inputs, as well as 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, etc. It is very reactive to quick temperature changes (detection in 30 [ms], stable measure in 100 [ms]). 

The use of thermocouple makes it easy to measure a temperature away from the module. However, if you would 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 50cm fine-wire twisted-pair thermocouple cables type K, which can be used to measure temperatures between -75°C and 260°C (PFA isolated, measure point non-isolated). To use a wider measure range of the device, you can use any more sophisticated thermocouple that you will find on a specialized shop.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub-GSM.

USB cables and enclosure to be ordered separately.
