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

📌 Overview

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

👉 It is widely used in:

  • 🌡️ Temperature monitoring systems

  • 🤖 Arduino & IoT projects

  • 🏠 Smart home automation

  • 🔋 Battery temperature protection

🧠 Working Principle

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

  • 🌡️ Temperature ↑ → Resistance ↓

  • ❄️ Temperature ↓ → Resistance ↑

👉 This follows the concept of Negative Temperature Coefficient

The module converts resistance changes into:

  • 📊 Analog voltage (AO)

  • 🔔 Digital signal (DO) using comparator
