reading pt1000 sensor with pi

Thu Sep 27, 2012 2:31 pm

I would like to ask if there is (an easy) way to plug a pt1000 sensor to raspberry pi and read it with some tool similar to digitemp for 1-wire sensors?

Any advise or link is welcome ;)

I do not think so. The Pi has no analogue input pins.

With a little help form an Arduino you can do it. Read the temperature with the arduino and send it to the Pi over USB. Open the USB port with a simple C program and read what arduino is sending. After that is up to you if you want to trigger valves, apply power to a relay to tart a motor etc. It is very simple.

I was thinking about this PT1000 temperature sensor since I want to measure the temperature on the solar collectors and the 1-wire sensors are not that good for temperatures above 80 degrees. Is there any digital alternative to 1-wire that could be easily used with pi without interacting over third party devices like arduino?

I used Maxim ICs for interfacing Pt100/Pt1000 sensors to microprocessors...

Normally they also send samples in small quantities to you (o;
