Energy Efficient Wireless Communication for IOT Enabled Greenhouses
With the rise of smart agriculture, greenhouses are increasingly adopting IoT technologies to monitor and control environmental conditions for optimal plant growth. However, continuous wireless communication between sensors and cloud platforms can lead to excessive energy consumption, especially in off-grid or solar-powered systems. This project presents an Energy-Efficient Wireless Communication System for IoT-Enabled Greenhouses, incorporating selective data transmission and a Flask-based web server for real-time monitoring and control. The system is developed using a NodeMCU (ESP8266) microcontroller, interfaced with a soil moisture sensor, temperature sensor, and LDR sensor to monitor key environmental parameters such as soil hydration, ambient temperature, and light intensity.
