  Greenhouse monitoring andcontrolling project is used to measure the various parameters like Temperature, Humidity, Light and soil moisture. Microcontroller displays these parameters on a LCD. Temperature, Humidity and Light is sensed by respective sensors, soil moisture is sensed by 2 thin metal rods or metal wires. Sensor output of Temperature is amplified and along with other 3 sensors, it is given to Analog to Digital Convertor ADC. Microcontroller controls these parameters and keeps them below predefined levels using relay interface and motor drivers. These relays can be connected to Fan/Heater and DC motors can be connected to respective devices. For demo purpose we have connected a 12 volt DC fan and a 12 volt DC bulb and two 12 volt DC motors. Values of temperature, humidity, light and soil moisture are send to a computer through serial port. These values can be displayed on PC using hyper terminal. But in this experiment we did only Automatic street light control , Unauthorized entering and automatic water motor on off DESCRIPTION

  WORKING PROCESS Automatic streetlight control is work when sunlight is low. When sunlight is less LDR starts and lights glows. Unauthorized entering is work at night. For that we connect a series of Tap switch with LDR. If someone come in front of the door. They will connect with the switch and an alarm will ring and light will glow. Automatic water motor on off switch is work on depend upon water level of water tank. At some low level of water come on that time motor will start. And at high level of water motor will stop automatically. It work basis of clock pulse.

  APPLICATIONS AND ADVANTAGES: 1.Can be used in green houses to control the temperature, soil moisture, humidity and light for the proper growth of plants 2. With little modification, this project can be used in Mechanical companies to measure various parameters of operating machines like temperature and light. 3. Temperature monitoring and controlling action can be used in home or various halls like conference room, seminar hall to control the temperature of room Future Development: 1. We can monitor more parameters like Humidity, PH of soil, pressure, water level and at the same time control them 2. We can send this data to a remote location using mobile or internet 3. We can draw graphs of variations in these parameters using compute

  Every technology hasgood aspect as well as bad aspect the important thing is, how we are using it. The real success of the sensor network technology depends mainly on its application in eradicating a harmful situation or in maintaining a good one. Designing an efficient application is one of the major challenges and sensor network challenges are application dependent 10 CONCLUSION
