Temperature Measuring

poos1 · 04/06/2013, 01:30 PM

I am doing a project to measure the temperature of my tank using a thermistor and Arduino. Please anyone suggests me a good circuit for interfacing the thermistor with the Arduino analog input.

These work well, are cheap, and you can run multiples off the same pin on the arduino. Each has a unique serial address that allows this. There are plenty of sketches online that can show you how to use them.

If I remember correctly, you only need 1 4.7k ohm resister for the circuit even when you use multiple sensors. I'll post some links after the Nascar race. :-)

ninja edit: race doesn't start for another half-hour, so here is a simple tutorial on using the ds18b20 temp sensor. http://www.hacktronics.com/Tutorials...-tutorial.html
