Energy Intensive Industries

Energy-saving and environmental protection has become the theme of the 21st century. Greenhouse is an energy-intensive industries. Every year, 35% of energy consumption on agricultural production is used for greenhouse heating in the world, which accounts for 15-40% of the cost of greenhouse production. For improving energy efficiency and protecting the environment, the reasonable control of greenhouse environmental parameters is significant. The design of solar greenhouse real-time environment monitoring and automatic control system is based on 8051 single-chip in the thesis. The temperature and humidity signal are obtained from DS18B20 digital temperature sensor and IH3605 humidity sensor. When the greenhouse temperature exceeds the set temperature, the device can be started by perform timely processing, then the user can read LED digital display temperature and humidity values.

Watering plants usually done manually using human power. that has risk negligence and inaccuracy. also, in time and cost is not efficient. Another factor that can affect the quality of crops is a factor of humidity and temperature. For those reason, writers made a tool that can work according to the level of humidity and temperature automatically and continuously. This tool uses Zelio Smart Relay as automatic controller. The 808H5V5 humidity sensor and LM35 temperature sensor is used as input. The LM35 temperature sensor detect the ambient temperature, where as 808H5V5 humidity sensor detect ambient air humidity, and time of watering adapted to the Smart Relay timer. The entire sensor input is programmed using ZELIO SOFT 2. Setting the temperature and humidity when the detected 30oC and >70% as well as the timeshows at 08.30 – 09.00 am and 16.00 – 16.30 pm the pump will automatically ON.

Currently, energy saving has become one of crisis that needs to be addressed by the entire world as it is known that energy saved is energy produced. Especially, power consumption at home plays a major role in energy saving. At times, the light is on when people forget to switch off the light while leaving the room. This may lead to waste of energy and economy issues. Thus, it is the need of the hour to propose automatic light control system that turns on and off automatically based on the human presence in the room. Sensors are used to detect the human presence in the room which automatically controls the light. Also, the proposed system alerts the user through mail when the room temperature is increased beyond certain level through temperature and humidity sensors.
