This paper introduces a radio sensing device that is easy to manufacture and maintain, easy to install and relocate, can store solar energy, resistant to typhoon and heavy rains, and has low power consumption. With the radio sensing devices constantly collecting information on environmental changes and sending data back to the backend system designated by the customer, our system can assist the farmers predicting the production period of crops in the area, which allow farmers to plan the different field operations. In this paper, we propose an unified sensor framework and compare our design with various hardware, software and mechanism of sensing devices in the literature. The height of our device is 275mm, the bottom circle radius is 63.3mm, the weight is less than 2kg, the minimum power consumption during radio transmission is only 0.58W, and the end point transmission distance can reach 16 kilometers. Our devices are highly integrated and low power, and have been commercialized and sold worldwide.
