Abstract: This project aims to develop a wireless sensing system to measure the temperature and humidity in greenhouse environment. The system contains the sensor nodes and main nodes. Sensor nodes include sensors and the ADC Megawin MCU (MPC82G516) and master node contains Megawin MCU (MPC82G516) and RS232 interface. The system can successfully measure the right humidity and temperature data and make the communication between sensor nodes and master nodes achievable which uses sensors sensing the environment variables and wireless transceiver module transmitting data. After the system got the humidity and temperature data, it will upload the data to a website, so the user can be informed of the data conveniently.
