Pi Plates

Pi-Plates THERMOplate


The Pi-Plates THERMOplate is an affordable and stackable temperature measurement plate designed exclusively for the popular Raspberry Pi single board computer. Each THERMOplate can support up to eight thermocouples and four DS18B20 digital temperature sensors for a total of twelve inputs. And like all of our products, they can be stacked and mixed with the rest of the Pi-Plates family. In addition, with the THERMOplate we are using plugable terminal blocks to eliminate the hassle of having to disassemble a stack of plates to add or remove signal wires. See below for detailed features for the THERMOplate.
