Pin Configuration

Component Documentation: 5K Cermet (Pack of 5)
Overview
The 5K Cermet is a ceramic metal film resistor, a type of fixed-value resistor commonly used in electronic circuits. This component is available in a pack of 5, providing five individual resistors with a nominal resistance value of 5 kilohms.
Pin Description
The 5K Cermet resistor has two pins, labeled as follows:
Pin 1:
Function: One end of the resistor
Description: This pin is one terminal of the resistor, where the electrical connection is made to the circuit.
Purpose: To connect the resistor to a voltage source, ground, or another component in the circuit.
Pin 2:
Function: The other end of the resistor
Description: This pin is the other terminal of the resistor, where the electrical connection is made to the circuit.
Purpose: To connect the resistor to a voltage source, ground, or another component in the circuit.
Connection Structure
To connect the 5K Cermet resistor in a circuit, follow these steps:
1. Identify the pins: Locate the two pins on the resistor, labeled as Pin 1 and Pin 2.
2. Determine the connection point: Decide where you want to connect the resistor in the circuit, such as to a voltage source, ground, or another component.
3. Connect Pin 1: Attach Pin 1 to the desired connection point in the circuit, ensuring a secure electrical connection.
4. Connect Pin 2: Attach Pin 2 to the other desired connection point in the circuit, ensuring a secure electrical connection.
5. Verify the connection: Double-check that the resistor is properly connected to the circuit, with no loose connections or short circuits.
Important Notes
When connecting the resistor, ensure that the pins are not reversed, as this can affect the circuit's performance or even cause damage.
The resistor should be connected in a way that respects its nominal resistance value and power rating to avoid overheating or failure.
Always follow proper safety precautions when working with electrical circuits, including wearing protective gear and using insulated tools.
By following these guidelines, you can correctly connect the 5K Cermet resistor in your circuit and utilize its fixed resistance value to achieve the desired functionality.

Code Examples

### Example 1: Basic Temperature Measurement using Arduino

This example demonstrates how to use the 5K Cermet thermistor to measure temperature using an Arduino board.

```c++
#define THERMISTOR_PIN A0
#define SERIES_RESISTOR 10e3
#define B_VALUE 3950

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

void loop() {
  int thermistorReading = analogRead(THERMISTOR_PIN);
  float vout = (thermistorReading  5.0) / 1023.0;
  float Rth = SERIES_RESISTOR / ((5.0 / vout) - 1);
  float temperature = 1 / (log(Rth / 10000) / B_VALUE + 1 / 298.15) - 273.15;
  Serial.print("Temperature: ");
  Serial.print(temperature);
  Serial.println(" C");
  delay(1000);
}
```

### Example 2: Temperature Data Logging using Raspberry Pi and Python

This example demonstrates how to use the 5K Cermet thermistor to log temperature data using a Raspberry Pi and Python.

```python
import time
import RPi.GPIO as GPIO
import math

GPIO.setmode(GPIO.BCM)
THERMISTOR_PIN = 17
SERIES_RESISTOR = 10e3
B_VALUE = 3950

def read_temperature():
  GPIO.setup(THERMISTOR_PIN, GPIO setInput)
  voltage = GPIO.input(THERMISTOR_PIN)  3.3 / 1023
  Rth = SERIES_RESISTOR / ((3.3 / voltage) - 1)
  temperature = 1 / (math.log(Rth / 10000) / B_VALUE + 1 / 298.15) - 273.15
  return temperature

while True:
  temperature = read_temperature()
  print("Temperature: {:.2f} C".format(temperature))
  time.sleep(1)
```

Note: In both examples, the thermistor is connected to a voltage divider circuit to provide a stable voltage supply. The SERIES_RESISTOR value should be adjusted according to the specific circuit design. Additionally, the code examples provided are for illustration purposes only and may require modifications to suit specific IoT projects.
