Key Components -

 

Sensors:

• Temperature Sensors: Devices like thermocouples or digital temperature sensors (e.g., DHT11, DS18B20) to measure ambient temperature.

​

• Humidity Sensors: Devices like capacitive humidity sensors (e.g., DHT11, DHT22, SHT31) to measure moisture levels in the air.

Microcontroller/Processor:

• A microcontroller (e.g., Arduino, Raspberry Pi) to collect data from the sensors and process it.

​

• Handles communication between the sensors and the user interface.

Data Transmission Module:

• Wired: Ethernet module or RS-485 for local area network connectivity.

​

• Wireless: Wi-Fi (ESP8266/ESP32), Bluetooth, or LoRa for remote monitoring.

Data Storage:

• Local storage (SD card) or cloud storage (AWS, Google Cloud, Azure) for historical data logging and analysis.

User Interface:

• A web application or mobile app for real-time monitoring, data visualization, and alerts.

​

• Dashboard displaying current temperature and humidity readings, historical data, and trends.

Power Supply:

• Batteries for remote setups or a stable power supply for stationary installations.

​

Features -

​

Data Collection:

• Sensors measure temperature and humidity at regular intervals.

​

• The microcontroller reads sensor data and processes it.

Data Transmission:
