220V Microwave Motion Sensor with Button – 0-6m

Description

What it is

The Microwave Motion Sensor 220V with Button is an electronic device that detects the presence of movement in a defined area. It uses microwave sound waves to measure distance and movement of objects within its range of action.

Features

• Power Supply: 220V
• Detection Range: 0-6 meters
• Interface: Button

What it is for

This sensor is ideal for DIY and Arduino projects that require movement detection in domestic or industrial environments. It can be used to create simple alarm systems, turn lights on automatically when movement is detected, or control other electronic devices based on the presence of people. Its compatibility with Arduino and ESP makes it versatile for a wide range of applications.

Tutorial: How to Use Microwave Motion Sensor

This detector is ideal for projects requiring movement detection in domestic or industrial environments. Useful for beginners and intermediates.

What you need

• MicroWave Motion Sensor
• Arduino UNO or compatible
• 220V power supply cable
• 10kΩ resistor

Steps

1. Check the datasheet for the sensor specifications.
2. Connect the sensor to the Arduino via digital pins.
3. Power the sensor with the 220V cable.
4. Connect the 10kΩ resistor between the GND pin and a digital pin of the Arduino.
5. Upload the following code to your Arduino.
6. Test the sensor by placing and removing an object in front of it.
7. Verify that the sensor LED turns on and off correctly.
8. Check the datasheet for battery life duration

Example code

void setup() {
  pinMode(2, INPUT);
  pinMode(3, OUTPUT);
}

void loop() {
  if (digitalRead(2) == HIGH) {
    digitalWrite(3, HIGH);
  } else {
    digitalWrite(3, LOW);
  }
}

Mini project

Build a simple alarm system. Connect the sensor to an LED and a bell to alert when movement is detected.

Common mistakes

• Incorrect power supply: ensure you are using a 220V cable.
• Incorrect connection: check that the sensor is correctly connected to the Arduino.
• Missing resistor: the circuit will not work without the 10kΩ resistor.
• Incorrect Arduino code: check the code and make sure it is correct.

Recommended accessories

• Arduino UNO
• LED
• Buzzer
• USB cable for loading
