10K Temperature Sensor (Thermistor) - Color may Vary

🌡️ 10K NTC Thermistor Temperature Sensor
🧩 Overview
NTC (Negative Temperature Coefficient) thermistor
Resistance changes with temperature variation
Widely used for temperature sensing & control
Compatible with Arduino, ESP32, Raspberry Pi
⚙️ Working Principle
Thermistor resistance decreases as temperature increases
Forms a voltage divider circuit with a fixed resistor
Output voltage changes based on temperature
Microcontroller converts voltage → temperature value
