In this paper, the authors present the design and implementation of wireless sensor network that can monitor the air temperature, humidity, light intensity in a crop field and from remote places also. The system consists of nodes, which are equipped with small size application specific sensors and radio frequency modules. The sensor data is transmitted via radio frequency link to the centrally localized computer terminal for data logging and analysis. This data can be monitor from the remote places by uploading the data into the internet, also the sensor nodes can additionally be programmed from the computer terminal itself according to the changing needs of farmers thus preventing the need for redeployment of the wireless sensor network every time some changes are to be made.
