# arduino temperature sensor with thermistor

### Make an Arduino Temperature Sensor (thermistor tutorial ...

· 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 Arduino will measure the voltage at a point between the thermistor and a known resistor. This is known as a voltage divider. The equation for a voltage divider is:

### Make an Arduino Temperature Sensor (Thermistor Tutorial)

If you don’t have a multimeter, you can make an Ohm meter with your Arduino by following our Arduino Ohm Meter tutorial. You only need to know the magnitude of your thermistor. For example, if your thermistor resistance is 34,000 Ohms, it is a 10K thermistor. If it’s 340,000 Ohms, it’s a 100K thermsitor.

### 2 pin temp censor - Sensors - Arduino Forum

· I never tried thermistors but from what I've read, they aren't accurate, even 2 thermistors of the same model, could show different values at the same temperature. So you have to make your own lookup table by using a thermometer (or 2, to be more accurate) and measure the resistance at different temperatures. You could use a sensor such as the DHT22 (they are accurate, I have 2 of them and ...

### Temperature Sensor Using NTC Thermistor (Arduino/NTC)

· Temperature Sensor Using NTC Thermistor (Arduino/NTC) Advertisement. A thermistor (THERMally sensitive resISTOR) is an electrical resistance whose value changes with the temperature.

### Temperature Measurement with a Thermistor and an Arduino

thermistor indicates temperature by a change in electrical resistance. Theanalog input pins of the Arduino can only measure voltage, so the electricalresistance of a thermistor cannot be measured directly1. A simple technique forconverting the (variable) resistance of the thermistor to a voltage is to use thethermistor in a voltage divider, as shown in the left side of Figure 1. The rightside of Figure 1 is a representation of the voltage divider circuit connected toan Arduino.
