Dear Colleagues,
We have here a couple of K8067 sensors in combination of a K8055 USB and a raspberry. We measure 24/7 and have the temperatures stored in a postgresql database. The K8055 is USB alimented. The 12v alimentation for the K8067 is not that efficient (consumes idle more than 3 W). I tried the K8067 on a use an efficient power supply (5v) - and seems to ‘work’, meaning I got a tension. What should I do to translate the voltages to temperatures ? the documentation provides a formula (for 12v ) - but not for 5V. Recalibrate or use a step up to go from 5V to 12V ?
Thank you very much in advance, Pieter
