In this project, we are using sensors to measure temperature, Humidity for agriculture environment monitoring using Wi-Fi technology. There are other technologies such as Infrared, RF, Bluetooth, Zigbee communication but WI-FI has certain advantages over these technologies.
Considering the advantages of Wi-Fi an advanced automation system was developed to control the appliances in the house. It is a wireless technology that uses radio frequency to transmit data through the air. Wi-Fi has initial speeds of 1mbps to 2mbps.Wi-Fi transmits data in the frequency band of 2.4 GHz. It implements the concept of frequency division multiplexing technology. Range of Wi-Fi technology is 40-300 feet. The controlling device for the automation in the project is a Microcontroller. The sensor parameters data is sent to PC or handheld Android Device over Wi-Fi using Microcontroller. The electrical loads such as Fan, Lights are controlled automatically through current driver and relays based on the sensor condition.
Advantages of Wi-Fi Communication :
1. Wi-Fi is user-friendly interfacing.
2. Low power consumption.
3. Long life.
4. Reduced installation costs.
5. Easy implementation,installation, and coverage.
6. System scalability and easy extension
