Abstract：Toaddressthe problem thatthe temperatureandhumidityadjustmentof common plasticgreenhouses needs manualrolingcotoncurtains andventilationoperation，whichistime-consumingandlabor-intensive，this studydesignsa temperature and humidity system for plastic greenhouses basedon PIDcontrol technology.The system featuresamodular designfor temperatureandhumiditymeasurement，controloutput，displayandalarm functions，whichenhancesthe conectivityandanti-interference capabilitybetweenmodules，improvingeficiencyand stability.This studyanalyzesand optimizes thecontrolalgorithm，followedbysingle-factorandcomprehensivefield tests insmall-scale greenhouses.The resultsshow that when the initial seting range of temperature and humidity is preset at 25∘-27∘C and 50%-60% ，the average error rate of the system control is 1.2% ，meeting the plant growth requirements of the test cell.This research results provides a reference scheme for the automation technology upgrade of commonplastic greenhouses.
