XH-W2020 12V Digital Display Electronic Thermostat Control Switch

Description

What it is

The XH-W2020 thermostat switch is an electronic device that allows automatic temperature regulation in domestic or industrial environments. It features a digital display that shows the set and detected temperature.

Features

• Operating voltage: 12V
• Digital display
• Automatic temperature regulation

What it is for

The XH-W2020 thermostat switch can be used to create automatic ventilation systems by connecting it to a fan to regulate temperature based on settings. It is also useful for environmental control in homes, offices, or workshops.

Tutorial: How to use XH-W2020

The XH-W2020 thermostat switch automatically regulates temperature, ideal for environmental control in homes or workshops.

What you need

• XH-W2020
• Arduino
• 10kΩ resistor
• 12V power cable

Steps

1. Connect the 12V power cable to the VCC pin of the XH-W2020.
2. Connect the GND pin of the XH-W2020 to the GND of your circuit.
3. Connect the OUT pin of the XH-W2020 to a digital pin on your Arduino.
4. With power and ground connected, check the remaining pins on the datasheet.
5. Write a simple sketch to control the thermostat state: `digitalWrite(pino_XH_W2020, HIGH);`
6. Upload the sketch to your Arduino and check the display for temperature.
7. Adapt the thermostat to your environment by setting the desired temperature.
8. Verify operation by checking the state of the output pin with a multimeter.

Example code

```
void setup() {
  pinMode(pino_XH_W2020, OUTPUT);
}

void loop() {
  digitalWrite(pino_XH_W2020, HIGH);
}
```

Mini project
