Inexpensive 6-channels temperature scanner
Did you ever look for a cheap temperature monitor capable of collecting up to six sensor readings?
Johnathan Hottell needed to monitor the engine temperature of his LB7 Duramax diesel truck to avoid over-heating problems in hot days. Looking for commercial products, he found several quite expensive scanners (around hundreds of dollars), so he decided to build its own monitor using an Arduino Pro Mini, six NTC thermistors and a Nokia 3310 LCD screen to display the temperature readings.
The result, which is described here in great details, cost around 40 $.
