Thermistor Calculator

The Thermistor Calculator is a specialized tool designed to help users determine the resistance of a thermistor at a given temperature, or vice versa. Thermistors are temperature-sensitive resistors commonly used in electronic circuits for temperature sensing, control, and compensation. This calculator simplifies the process of converting between temperature and resistance using the Steinhart-Hart equation, which models the relationship between these two variables.

Key Features:

• Calculates resistance based on temperature input or temperature based on resistance input.
• Supports both Negative Temperature Coefficient (NTC) and Positive Temperature Coefficient (PTC) thermistors.
• Uses the Steinhart-Hart equation for high accuracy.
• Allows customization of thermistor parameters (e.g., beta value, reference resistance, and reference temperature).

How to Use:

1. Select the calculation mode: Resistance from Temperature or Temperature from Resistance.
2. Enter the known value (temperature in °C or resistance in ohms).
3. Input the thermistor parameters (e.g., beta value, reference resistance at 25°C).
4. Click Calculate to obtain the result.

Example Use Cases:

• Determining the resistance of an NTC thermistor at 50°C for circuit design.
• Finding the temperature corresponding to a measured resistance of 10kΩ in a PTC thermistor.

Notes:

• For accurate results, ensure the thermistor parameters match the manufacturer's specifications.
• The Steinhart-Hart equation is most accurate for small temperature ranges.
