In the recent scenario, monitoring the greenhouse automatically with solar energy is the need of the hour due to power constraints and climatic change. The proposed system introduces a new technique for monitoring and controlling the greenhouse environment. This paper focuses on low-cost sensor modules for Arduino microcontroller. We are measuring three sensing parameters like humidity, temperature and soil moisture and displaying the current environment scenario on the LCD screen. These physical parameters are continuously monitored, based on the requirement the actuators are controlled like natural heating unit, cooler and sprinkler. These actuators are driven by microcontrollers through a relay. We have implemented an effective power management unit which is driven by solar power. Proposed system has an extra feature of detecting animal intrusion system, and its implementation is done in small scale. © Springer Nature Singapore Pte Ltd. 2018.
