    Security is primary concern for everyone. This Project describes a design of effective security system that can monitor a greenhouse with different sensors. Abnormal raise in temperature and the smoke generated through any source can be monitored by the status of each individual sensor and day/night monitoring sensor is also given. Here moisture sensor is also placed to check whether the soil is dry or wet which can be used in agricultural fields. A switch is also provided to spray the pesticide. Green House monitoring is being done with the help of all these sensors. The project is built around the ARM7 micro controller. This micro controller provides all the functionality. People will be alerted with a buzzer and necessary measures can be taken immediately. An IOT module is also interfaced to the controller to send updates using internet. Few electrical appliances are also connected to respond according to their respective sensor status which is being monitored by our controller. We can place this module either at a door near home or at offices, factories or any other place where we need monitoring every minute for the purpose of security/surveillance. This project uses regulated 5V, 750mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.
