6-Channel Temperature Monitor & Logger
Temperature is an important parameter to control in many industrial processes. At home, the fridge, freezer, heater, kitchen oven, and air conditioner all measure and adjust the temperature to get their job done. Weather stations, cars, computers, tablets and smartphones keep an eye on temperature too. Temperature may very well be the world’s most surveilled physical quantity.

Download the BOM list
The BOM (Bill of Materials) is the technically exhaustive listing of parts and other hardware items used to produce the working and tested prototype of any Elektor Labs project. The BOM file contains deeper information than the Component List published for the same project in Elektor Magazine. If required the BOM gets updated directly by our lab engineers. As a reader, you can download the list here.
