Smart Motion Detection Adapter With Blynk IoT and ESP8266

This project is a smart motion detection system using an ESP8266, an RCWL-0516 microwave radar sensor, and Blynk IoT, all enclosed inside an adapter case. The system detects motion and updates the Blynk IoT app by turning on an LED widget in the dashboard. An automation is created in Blynk to send a notification when motion is detected. Additionally, a physical LED is connected to the ESP8266, which blinks when connected to Wi-Fi.

Electronics Components:

1. ESP8266 (NodeMCU / Wemos D1 Mini)
2. RCWL-0516 Microwave Radar Sensor
3. Hi-Link 5V Power Module
4. LED (for Wi-Fi connection indicator)
5. 220Ω Resistor (for LED)
6. Jumper wires / Soldering wires

Tools & Enclosure:

1. Adapter Enclosure (any suitable size)
2. Soldering Kit
3. Insulation tape
4. Glue Gun (for enclosure fitting)

Software & Apps:

1. Arduino IDE (for coding)
2. Blynk IoT App (available for Android & iOS)
3. Fritzing or EasyEDA (for circuit design - optional)

Working Principle

1. The RCWL-0516 sensor detects motion using microwave signals.
2. When motion is detected, the ESP8266 sends a signal to Blynk IoT, lighting up the LED widget in the app.
3. In Blynk, we create an automation to send a notification when the LED widget is triggered.
4. The physical LED on the ESP8266 blinks when the device is successfully connected to Wi-Fi.

Connections:

1. RCWL-0516 Sensor
2. VCC → 3.3V (ESP8266)
3. GND → GND (ESP8266)
4. OUT → D6 (ESP8266)
5. Wi-Fi Status LED
6. Anode (+) → D5 (ESP8266)
7. Cathode (-) → GND (ESP8266)
8. 220Ω Resistor in series with LED
9. Power Supply (Hi-Link 5V)
10. AC Input → Power Source
11. DC Output (5V, GND) → ESP8266 Vin & GND

Replace this lines of code with your own details Wi-Fi and Auth token

Visit My GitHub for the Arduino code and Circuit https://github.com/N-08Labs/Microwave-Radar-based-Security-Device

Install the Blynk IoT App on your smartphone.

Create a new project and select ESP8266 as the device.

Add a LED Widget:

1. Pin: V1
2. Color: Any

Create an Automation:

1. Trigger: When V1 (LED widget) is ON
2. Action: Send a Notification

Copy the Auth Token and paste it into the Arduino code.

If you're not sure on how to creating blynk IoT dashboards then please watch some videos on youtube there are plenty of them https://youtu.be/LwFUjJAT_88

Blynk IoT https://blynk.io/

If you're a beginner then you might get confused

so, I would suggest watching my YouTube video
