10K Thermistor Temperature Sensor Module(3 Pin) Documentation

Component Name

10K Thermistor Temperature Sensor Module (3 Pin)

Overview

The 10K Thermistor Temperature Sensor Module is a compact, 3-pin device designed to measure temperature in a wide range of applications. This module combines a thermistor, a type of thermally sensitive resistor, with a signal conditioning circuit to provide a high-accuracy, analog output signal.

Functionality

The 10K Thermistor Temperature Sensor Module is designed to convert temperature changes into a proportional voltage signal. The module operates on the principle of thermistor resistance variation with temperature. As the temperature increases, the thermistor's resistance decreases, and the output voltage signal changes accordingly. The module's signal conditioning circuit amplifies and filters the thermistor's signal to provide a stable, analog output voltage.

Overview
The 10K Thermistor Temperature Sensor Module is a three-pin device designed to measure temperature accurately and efficiently. This module is widely used in Internet of Things (IoT) applications, robotics, and various industrial projects. The thermistor element is a thermally sensitive resistor that changes its resistance in response to temperature changes, allowing for accurate temperature measurement.
Pin Description
The 10K Thermistor Temperature Sensor Module has three pins, labelled as VCC, GND, and OUT. Each pin has a specific function, as described below:
### VCC (Pin 1)
Function: Power supply pin
Description: This pin connects to the positive voltage supply of the circuit, typically +5V or +3.3V.
Notes: Ensure the voltage supply is within the recommended range to avoid damaging the module.
### GND (Pin 2)
Function: Ground pin
Description: This pin connects to the negative voltage supply or ground of the circuit.
Notes: A stable and noise-free ground connection is essential for accurate temperature measurements.
### OUT (Pin 3)
Function: Output pin
Description: This pin provides an analog output voltage proportional to the temperature measured by the thermistor.
Notes: The output voltage ranges from 0V to VCC, with higher voltages indicating higher temperatures.
Connection Structure
To connect the 10K Thermistor Temperature Sensor Module, follow this step-by-step structure:
1. Connect VCC (Pin 1) to Power Supply (+5V or +3.3V)
Connect the VCC pin to the positive voltage supply of your circuit, such as a breadboard or a microcontroller's power pin.
2. Connect GND (Pin 2) to Ground

Overview

The 10K Thermistor Temperature Sensor Module is a 3-pin module designed to measure temperature in various applications. It features a thermistor, a type of resistor that changes its electrical resistance in response to changes in temperature. The module provides a simple and accurate way to measure temperature, making it suitable for use in IoT projects, robotics, and other electronic applications.

Pinout

VCC: Power supply pin (typically 5V)
 GND: Ground pin
 OUT: Analog output pin (connects to an analog input pin on a microcontroller)

Specifications

Temperature measurement range: -20C to 100C
 Thermistor resistance: 10k at 25C
 Accuracy: 1C
 Response time: 10-15 seconds
 Operating voltage: 3.3V to 5V

Code Examples

### Example 1: Arduino Temperature Measurement

In this example, we'll use an Arduino Uno board to read the temperature from the thermistor module and display it on the serial monitor.
```c++
const int thermistorPin = A0;  // Analog input pin

void setup() {
  Serial.begin(9600);
}

void loop() {
  int sensorValue = analogRead(thermistorPin);
  float voltage = sensorValue  5.0 / 1024.0;
  float temperature = (voltage - 0.5)  100.0;
  Serial.print("Temperature: ");
  Serial.print(temperature);
  Serial.println(" C");
  delay(1000);
}
```
In this code, we read the analog value from the thermistor pin using `analogRead()`. We then convert the analog value to a voltage reading and calculate the temperature using the thermistor's characteristic curve.

### Example 2: Raspberry Pi Temperature Measurement with Python

In this example, we'll use a Raspberry Pi board with Raspbian OS to read the temperature from the thermistor module using Python.
```python
import time
import board
import Adafruit_ADS1x15

adc = Adafruit_ADS1x15.ADS1115(address=0x48, busnum=1)

while True:
    sensor_value = adc.read_adc(0, gain=1)
    voltage = sensor_value  5.0 / 32767.0
    temperature = (voltage - 0.5)  100.0
    print("Temperature: {:.2f} C".format(temperature))
    time.sleep(1)
```
In this code, we use the `Adafruit_ADS1x15` library to read the analog value from the thermistor pin using the ADS1115 analog-to-digital converter. We then convert the analog value to a voltage reading and calculate the temperature using the thermistor's characteristic curve.

Notes

When using the thermistor module, ensure that the power supply voltage is within the specified range (3.3V to 5V).
 The thermistor module may require calibration to achieve accurate temperature readings.
 The response time of the thermistor module is approximately 10-15 seconds, so it's essential to consider this when designing your application.
