Motion Sensor

This project uses an ESP32 module connected to a motion sensor to send a "motion detected" message when it detects activity.

Components

• ESP32 module
• Motion sensor
• 3x socket-to-socket wires

With the ESP32 module disconnected from your laptop

1. Connect a wire between the gnd pin of the ESP32 module and the gnd pin of the motion sensor.
2. Connect a wire between the vin pin of the ESP32 module and the vcc/5v pin of the motion sensor.
3. Connect a wire between the d13 pin of the ESP32 module and the out pin of the motion sensor.

Developing

After connecting the ESP32 module to your laptop, set up a new PlatformIO project as described in the README.

This project comes with 5 include files, each building on the last to progressively guide you through the steps of this exercise.

You can use these examples by bringing each one into the Main.cpp file.

• Step 1 - Make the LED blink
• Step 2 - Add Serial monitoring
• Step 3 - Add WiFi
• Step 4 - Add MQTT
• Step 5 - Add Motion Sensor

See motion sensor steps for more details on each step.
