Pt100 with Domoticz

Post by Metlik »

Hello!
I have a several (16 - sixteen) PT100 temperature sensors (thermo couples). Which interface You can suggest (or better to use), to connect them and monitor the temperature using Raspberry Pi3 and Domoticz?
Thank you in advance!

I do not know of any device that takes PT100 as a sensor. You can build something yourself using an Arduino. http://www.instructables.com/id/Reading ... g-Arduino/ but you will need some additional analog circuitry to get this working. The Arduino (at least the Nano), has 10-bit analog inputs you can use.
