In this project the process variables like Temperature, Humidity are sensed and the i r continuous reading is transferred to a remote PC via wireless . The project was initially computed and monitored on LabVIEW software and then its hardware circuit is prepared. The minimum response time between sensing and controlling is very small (few milliseconds) . Minimum response time for ON and OFF the con trol relay was found in micro sec onds . The parameter range can be c ontrolled by the programmer controller. A greenhouse environment parameters monitoring system based on wireless communication technology has been developed, which realizes the measurement, summary and control of temperature, humidity and the other paramete rs.
