A computerized dynamic parameters measuring system for fruit tree moisture


, : A computerized dynamic parameters measuring system for fruit tree moisture. Nongye Jixie Xuebao = Transactions of the Chinese Society of Agricultural Machinery 32(3): 71-74

The operation principle, technical index and the design of hardware and software of the microcontroller 89C51, a computerized dynamic instrument for measuring water conditions of fruit trees, are discussed. The instrument was used to measure flow rate of transpiration sap, soil moisture, photon flux density, temperature and moisture in the air, which enabled long-time, dynamic and on-site measurements.
