Design a kind of basis weight instrument based on wireless transmission technology, which adapt to the basis weight measurement and control system. Show the hardware and software structure. It uses C8051F353 as MCU, and uses CC1100 as wireless communication chip. The instrument can control the scanning bracket to detect paper’s basis weight on line automatically, or remote manual control. It may connect to wireless sensor network, or integrated in DCS. The precision is high to 0.05%. It can be used to detect all kinds of paper and board by using different radiate source.

Water and fertilizer are two important factors in seedlings growth and development, the reasonable management of water and fertilizer can play a greater growth potential for seedling, and blind management of water and Fertilizer not only is harmful for seedling growth, but also will lead to the water resource waste and environmental pollution. In order to precisely determine the seedlings fertilizer demand, this paper presents a method seedlings fertilizer and water measurement and control system based on wireless sensor network, the system can realize automatic deployment of information acquisition node, data self-organization transfer, namely, wireless communication, and can accurately detect information of soil water and fertilizer and identify water and Fertilizer on the best demand of seedlings growth stages for different seedlings, different regions, different period of climate and seedling growth status, so the best water and fertilizer control is achieved in seedling cultivation. This system were introduced and analyzed from the hardware structure, software structure and so on in this paper, and it has the advantages of low power consumption, low cost, good robustness, flexibility and so on. The experiment results shown that the system is practical and efficient, which can be applied in farmland, and nursery area.
