Microprocessor-based humidity controller

The Microprocessor-Based Humidity Controller is a Z-80 based system primarily involved in the monitoring of relative humidity within a given environment. It\u27s primary function is to continually check the relative humidity of a closed environment, compare this with the desired relative humidity base level that is pre-defined, and then activate (or deactivate) the device to adjust the relative humidity to it\u27s set-point value. The system employs the wet-bulb and dry-bulb concept in sensing the relative humidity. The relative humidity corresponding to the wet and dry bulb temperature readings are searched from the relative humidity table. The switch-on/switch-off technique is used in activating and deactivating the device. The group would like to recommend the Microprocessor-based Humidity Controller to industrial, chemical, with emphasis on agricultural applications where relative humidity is a vital factor that others usually take for granted thinking they could not do anything about it, though certain humidity conditions may affect the quality of the desired product output. One such application the mushroom culture, whose humidity requirement range has been adopted. Based on the group s objectives, methodology, recommendation and major findings, we therefore conclude that relative humidity could be controlled
