🌑️ 10K Thermistor Temperature Sensor Module (4-Pin) 

πŸ“Œ Overview

The 10K Thermistor Temperature Sensor Module is a temperature sensing module based on a 10KΞ© NTC thermistor.

πŸ‘‰ It is widely used in:

  • 🌑️ Temperature monitoring systems

  • πŸ€– Arduino & IoT projects

  • 🏠 Smart home automation

  • πŸ”‹ Battery temperature protection

🧠 Working Principle

The module uses an NTC thermistor (Negative Temperature Coefficient):

  • 🌑️ Temperature ↑ β†’ Resistance ↓

  • ❄️ Temperature ↓ β†’ Resistance ↑

πŸ‘‰ This follows the concept of Negative Temperature Coefficient

The module converts resistance changes into:

  • πŸ“Š Analog voltage (AO)

  • πŸ”” Digital signal (DO) using comparator
