I have tried to use this guide to help me but when that didn't work I found this post (which gave me a nice visual) but still the Raspberry Pi cannot see my sensors. I have upgraded to the unsupported wheezy and ran this (with same result)

I've then used the console to run;

sudo modprobe w1-gpio
sudo modprobe w1-therm
cd /sys/bus/w1/devices/

This all works fine. However, when type ls, the guide tells me that I should see the serial number of the sensor listed followed by w1_bus_master1.

All I actually get is w1_bus_master1, but no serial number. I've tried everything I can think of (which isn't much). Is anybody able to offer some guidance on what the problem might be?

I have two sensors: (I think the reason is the type of sensors but ???)

  • LM60BIZ/NOPB
  • LM19CIZ/NOPB

Both from Mouser.com

I have two Rev. 1 Raspberry Pi and neither board can see these.

What could I be doing wrong?

The LM60 and LM19 are analog sensors, and the GPIO ports have no analogue inputs. You'll need a DS18B20 digital sensor.

  • Great, thanks. I picked up a new digital DS18b20 sensor and all is working now.
