The basic function of a greenhouse is to provide a protective environment for crop production. It monitors various factors such as soil moisture, temperature, light intensity, humidity. A traditional approach to measure these factors means individually manually taking measurements and checking them at various times. This application implements remote monitoring system using bluetooth technology. In this we are using android phone app to monitor physical parameters and status of controling action of the electrical loads.
The controller ATMEGA328 monitors sensor inputs continuosly using bluetooth module and displays on the 20×4 LCD. We are using DHT11 which gives parameters such as temperature and humidity combined in one sensor. LDR is for light intensity and soil moisture for soil status either dry or wet. We are using regulated power supply for all the units.
We are using different loads such as FAN,Lights, Sprayer, Water Motor pump which are automatically controlled based on corresponding sensor parameter values.
