Temperature sensor with cool thermistor Answered
Hi, I am trying to make a temperature sensor using a thermistor. I've made a basic circuit using an Arduino and some tutorials from this site and couple others, which works well but the thermistor heats up way too much - perhaps to about 50 or 60 degrees - but it needs to stay around room temperature for my application. I'm using a 5V output from an Arduino through a 15Ohm thermistor - am I doing something wrong?
Many thanks for the help!
The one I've made is almost identical to the one in this tutorial: http://www.circuitbasics.com/arduino-thermistor-temperature-sensor-tutorial/ except a different thermistor
