📌 What is Sensor Data?
Electronic sensors collect information from the physical world. Examples include:
- 🌡️ Temperature sensors (DHT11, DS18B20)
- 💧 Humidity sensors
- 🌫️ Gas/Smoke sensors (MQ-2, MQ-135)
- 🎛️ Pressure sensors
- 📍 Motion sensors (PIR)
- 🔆 Light sensors (LDR)
🖥️ How Servers Use Sensor Data
Sensors send data to a server using HTTP POST, MQTT, WebSocket or API calls. The server:
- Stores readings in a database
- Analyzes or filters data
- Sends alerts (SMS/Telegram/email)
- Displays real-time values in a dashboard
📊 Real-Time Sensor Data Example
This demo updates the values every 1 second (simulated for example):
🌡️ Temperature: — °C
💧 Humidity: — %
🔆 Light: — lx
💧 Humidity: — %
🔆 Light: — lx
