Design of Greenhouse Temperature Measurement and Control System Based on MCU

A greenhouse temperature measurement and control system was designed，using MCU as main controller. Design objectives and design requirements were analyzed，corresponding design scheme was formulated.Through design of hardware module and software subroutine，building module required by the system was established.Combined with hardware and software of the system，system′s accuracy was tested.Test of the system indicated that desired design purpose was achieved，while the system could display real-time temperature data，and could control temperature using keyboard.
