- What is Sensor Data?
- Sensor data is information collected from the environment, such as temperature, light intensity, gas levels, or movement.
- Microcontrollers convert this data into numbers we can read and use.
- Real-Time Data Collection
- “Real-time” means getting the data as it happens without delay.
- Example: A thermometer showing the current temperature every second.
- How Data is Collected
- Step 1: Sensor detects a physical change (heat, light, motion).
- Step 2: Sensor converts it into an electrical signal.
- Step 3: Microcontroller reads the signal using its ADC (Analog to Digital Converter).
- Step 4: Data is displayed for the user to see.
- Tools for Displaying Data
- Arduino Serial Monitor → Displays values sent from Arduino board.
- Python Shell/Thonny → Displays values from Raspberry Pi Pico.
- Why Display Sensor Data?
- Helps in monitoring systems like weather stations, air quality monitors, alarms, and industrial machines.
- Makes it possible to control devices based on sensor readings.
