[Thermistor datasheet](https://www.vishay.com/docs/29049/ntcle100.pdf) ![pic](./thermistor_schem.jpg) A thermistor is a device whose resistance varies as a function of temperature. It is typically used in a voltage divider circuit. Below is the data from the datasheet. T as a function of R between 0 and 100 C. Make this plot, read data from [spreadsheet (csv)](./thermistor_10K_NTC.csv) using [this](./plot_csv_thermistor.py) Python code. ![Thermistor](./Thermistor_data.png) [Tutorial on using a thermistor](https://create.arduino.cc/projecthub/Marcazzan_M/how-easy-is-it-to-use-a-thermistor-e39321) Our datasheet gives the formula for converting resistance to temperature in a slightly different way than this tutorial. Here's the data and the fit, using the datasheet formula. To make this plot, I created a spreadsheet from the device datasheet information. I imported this data into a Python array using the code linked below. Then calculated and plotted the function given in the datasheet as the model for T vs R. This plot is generated by [this](./plot_csv_thermistor_logfit.py) Python code. ![](Thermistor_modeled.png) Now we can confidently use this formula in the Arduino [Here is a Thermistor-reading Arduino code](thermistor_read.txt) [link to temperature-control project notes June 2020](./../../Projects/Temp_control/index.html)
