NTC Thermistor Temperature Sensor Module 3 Pin

🌡️ NTC Thermistor Temperature Sensor Module – 3 Pin

Analog Temperature Detection for Arduino, ESP32, and More

The NTC Thermistor Sensor Module is a low-cost, analog temperature sensing module based on a Negative Temperature Coefficient (NTC) thermistor. As temperature increases, the resistance of the sensor decreases, allowing you to read changing temperature values using any microcontroller's analog input.

⚙️ Technical Specifications

✅ Features

• 🌡️ Accurate analog temperature readings using NTC thermistor

• 🔌 Easy to connect via 3-pin header (VCC, GND, OUT)

• 📊 Output decreases as temperature increases

• 🧠 Compatible with Arduino, ESP32, STM32, Raspberry Pi (via ADC)

• 🛠️ Ideal for thermostats, climate control, or overheat protection systems

🧪 Arduino Wiring Example

Sample Arduino Code:

cpp
CopyEdit
int sensorPin = A0;
float tempReading;

void loop() {
  int value = analogRead(sensorPin);
  float voltage = value * (5.0 / 1023.0);
  Serial.print("Analog Output: ");
  Serial.println(voltage);
  delay(500);
}

For more accurate temperature readings, use a calibration table or convert resistance using the Steinhart-Hart equation.

📱 Applications

• Temperature alarms and monitoring

• Fan control systems

• Overheating protection in electronics

• DIY smart home climate projects
