thermistor relay circuit

What is a Thermistor? Thermistor Types, Thermistor Circuits

Now to calculate the voltage value for the thermistor we will use voltage divider circuit. V t =R/R+R t * V dd Now to solve this for we will get R t =V dd -V t /V t * R V t is our primary measurement while and R are our auxiliary measurement. Measure the resistor R value before connecting to the voltage divider through ohmmeter.

What does a thermistor do in a circuit? - Electronic Guidebook

Main purpose of a thermistor in a circuit. Just like how we have five senses (sight, smell, hearing, touch and taste) that help us interpret and navigate the physical world, a thermistor gives a circuit the ability to sense the physical world as well. It does this by allowing it to sense changes in temperature by varying its resistance.

thermistor, the resistance-versus-temperature circuits depend on the thermistor being operated in a "zero-power" condition. This condition implies that there is no self-heating of the thermistor as a conse-quence of current or voltage excitation. The resis-tance-versus-temperature response of a 10kΩ, NTC thermistor is shown in Figure 3.
