Introduction: Temperature Sensor Using Thermistor With Arduino Uno
Hi Guys in this instructables we will learn how to use Thermistor with Arduino.
Thermistor is basically a resistor whose resistance varies with variation in temperature.
So we can read its resistance and get the temperature from it & Thermistor is very cheap compared to other temperature sensors in market.
Step 1: Things You Need
For this tutorial you will need following things :
1x Arduino uno : https://www.utsource.net/itm/p/9221687.html
1x Thermistor (10k or 100k : i am using 10k here ) :
1x 10k resistor :
1x breadboard :. : https://www.utsource.net/itm/p/8031572.html
Few jumpers : https://www.utsource.net/itm/p/9221310.html
Step 2: Schmatics
The circuit is very simple so please connect everything According to shown in the schmatics and you will fine.
You can also refer the image i attached of my breadboard connections.
Step 3: Code
Copy the following code & upload it to arduino :
double Thermister(int data)
Step 4: Get Temperature on Serial Monitor
After uploading the code, then open the serial monitor and you can get your Thermistor's temperature on your serial monitor as i am getting, refer image provided and you will fine.
Have fun reading temperature with Thermistor.
