10 Pieces NTC MF58 3950 B 100K Ohm 5% Temperature Sensor Thermistor

Description

Tutorial: How to Use NTC MF58 3950 B 100K ohm 5% Thermistor

The NTC MF58 3950 B 100K ohm 5% thermistor is ideal for measuring temperatures in domestic and industrial environments. Useful for beginners and intermediate makers.

What you need

• Multimeter
• 10K ohm resistor
• Arduino Uno
• Connection cable

Steps

1. 1. Connect the thermistor to pin A0 of the Arduino.
2. 2. Connect the 10K ohm resistor between VCC and GND of the Arduino.
3. 3. Connect one end of the resistor to GND and the other to VCC of the Arduino.
4. 4. Connect the other end of the resistor to pin A0 of the Arduino.
5. 5. Load the Arduino code.
6. 6. Check the datasheet for resistance values at different temperatures.
7. 7. Test the thermistor with a multimeter.
8. 8. Verify correct operation with a sample sketch.

Example code

```int sensorPin = A0;
int sensorValue = 0;
void setup() {
  Serial.begin(9600);
}
void loop() {
  sensorValue = analogRead(sensorPin);
  Serial.println(sensorValue);
  delay(1000);
}```

Mini project

Build a simple digital thermometer using the thermistor and an LCD display.

Common mistakes

• Connect the thermistor directly to VCC and GND.
• Omit the pull-up resistor.
• Do not verify resistance values on the datasheet.
• Forget to verify correct functioning with a sample sketch.

Recommended accessories

• 16×2 LCD Display
• 10K ohm pull-up resistor
• Connection cable
• Multimeter
