Abstract
SHT10’s principle
I/O connecting circuit and working schedual are introduced.The decision of the greenhouse multi-points measuring system is made by taking the character of SHT10 and the demands of modern greenhouse measuring system.And then the soft and hardware of temperature & humidity measuring system is designed.Furthermore
a data boservating and measuring point choosing interface in the PC terminal is designed
a good condition for concentraling management of modern greenhouse can be provided.
