Simple Temperature Sensor Circuit Using Lm35 Ic C35 A basic thermistor circuit. let’s build a basic thermistor circuit to see how it works, so you can apply it to other projects later. since the thermistor is a variable resistor, we’ll need to measure the resistance before we can calculate the temperature. however, the arduino can’t measure resistance directly, it can only measure voltage. The working of this circuit is simple. it is operating at 9 volts. initially, when there is no heat the circuit will remain turned off. when the thermistor receives heat its resistance will be decreased and it will let the current flow. this will activate both the transistors and the voltage will be passed to led and it will light up.
Thermistor Temperature Sensor Circuit Eeweb Vrogue Co 1 t = a bln(r) c(ln(r))3 1 t = a b ln ( r) c ( ln ( r)) 3. where r is the resistance of the thermistor at temperature t (in kelvins). this is a general curve fitting equation to accommodate all ntc type resistors. the approximation of the relationship of temperature and resistance is “good enough” for most applications. Figure 1. the response characteristics of thermistors vs. rtd. in terms of temperature range, the rtd curve is near linear, and the sensor covers a much wider temperature range (commonly –200°c to 850°c) than thermistors due to the thermistor’s nonlinear (exponential) characteristics. Integrated circuit temperature sensors, thermistors, thermocouples and resistance temperature detectors; all have their pros and cons. in this white paper, i’ll focus on one of the most common temperature sensors, the thermistor; highlight some important considerations when using thermistors for temperature sensing applications; and compare.
