In my new Dacia Duster is missing unfortunately an outside temperature indication. A finished thermometer with LCD did not separate from there while the contrast with sunlight usually particularly is. I had still alphanummeric LED display in red there for this project in the best way am suitable. As microcontroller i used a ATTINY 2313. The temperature sensor is a 1-Wire-digital sensor, thus the alignment of the sensor is void.

Interesting project. I’ve seen a few of these custom builds for thermometer displays in cars which do not have them. This is one of the neater integrations! I was thinking of putting a post together for my site thermometer -20 which includes a few examples of all the custom build projects. Would provide some good diversity on the post topics.
