Yocto-Thermocouple

  

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, or to a WiFi network using a YoctoHub-Wireless-g.

The Valarm Pro Android app supports up to 4 Yocto-Thermocouple sensors at the same time so you can alert and upload data to the Valarm Tools Cloud with up to 8 channels of temperature! http://www.valarm.net/blog/new-valarm-pro-app-version-1-3-0/

Hi I'm wondering how long the thermocouple cables can be? I have a space that I have about 100 feet distance to travel. Also what gauge wire would you recommend?

3 - martinm (Yocto-Team)Friday,may 30,2014 11H44

@pam 20 AWG or thicker wire should be fine as long as you are free of electromagnetic interferences.

Hello. Can this thermacouple (or another) sensor be used to accurately measure soil temperature vs. ambient air temp? What precision would it have?

5 - martinm (Yocto-Team)Sunday,february 01,2015 6H06

@petero : if you're interested in precision, you should choose a Yocto-PT100:

Hi.

Im interested in displaying temperature probably not data logging or usb. Can I add a LCD to display current temperature?

@maturin You could use a mini-pc such as a Raspberry PI to drive a Yocto-Thermo-couple and a Yocto-Display such as described here: http://www.yoctopuce.com/EN/article/turn-your-raspberry-pi-into-a-network-multimeter but honnestly, if you are not interested in connectivity, you should find yourself a regular handheld thermometer.

You have provide great examples , why don't you provide an app like valarm.. it will be helpful . i want to save the data on smartphone and than later upload it to xively or in real time ... like i m able to do using pi or pc .
Please consider this . i tried valarm and i don't think it real worth money

@shelendra: we have no plan for any kind of turn-key software solution. Here at Yoctopuce, the plan is to focus on the hardware and make it easy to integrate. That way our customers only have to care about the software and can write their own solution suited to their need.

Yoctopuce, get your stuff connected.
