To slow down the process of global warming, aim at reducing green house gas emission. Reducing energy consumption would reduce CO2 emission effectively
The purpose of this project is to developed based on wireless sensor network technology. The developed system is low cost and robust and fully takes the advantages of zigbee
The environmental sensors embedded with zigbee router modules are distributed to different locations to connect the environmental data .with collected data and preset energy quota the control unit of the proposed system updates the status of each electrical appliance in order to minimize the energy consumption.
Wireless Sensor network (WSN) is a popular solution for energy management solution in building automation. In addition to technical sophistication, greater cost-efficiencies while maintaining high levels of functionality and reliability are high on the priority list for most wireless sensor developer's .while wireless systems reduce the wiring and labor cost in building automation technologies, there is an urgent need to enhance power efficiency and the range of the wireless digital signal transmission.
Wireless mesh networking technology is likely to address the issue surrounding wireless signal attenuation and offer better quality wireless signals.
In this project we are using two sections: first section is a transmitter in which we are using LDR and temperature sensor to get the light intensity and temperature that data will communicate with the serial ADC through receiver section using Zigbee (Tran receiver) and another transmitter section in which we are using Temperature sensor and ldr to get the temperature and light intensity through serial; ADC also communication via Zigbee.
At the receiver we are having two switches that with indicate whether transmitter1 or transmitter2 depend upon both sensor threshold value and the particular information is displayed on the LCD
Now a day's every system is automated in order to face new challenges. In the present days Automated systems have less manual operations, flexibility, reliability and accurate. Due to this demand every field prefers automated control systems. Especially in the field of electronics automated systems are giving good performance. And this is realized by making use of Zigbee technology for communication.
Zigbee is new wireless technology guided by IEEE 802.15.4 Personal Area Network standard. It is primarily designed for the wide ranging controlling applications and to replace the existing non-standard technologies.
It currently operates in 868MHz band at a data rate of 20Kbps in Europe, 914MHz band at 40kbps in USA, and the 2.4GHz ISM bands Worldwide at a maximum data-rate of 250kbps
The result of this project to reduce energy management for residential commercial building. The technology of Zigbee represents a wireless network which is highly reliable, networking, secure, low data rate, low power consumption.
