Abstract

The objective of this research is how to control proper room temperature and humidity in a straw mushroom producing house with the targets of 28-33oC temperature, and 80-90% relative humidity. Research was conducted by building a mushroom house (4m wide x 6m long x4m high), steel framed, asbestos roofed with 3mm plywood ceiling, and 60% screen net wall layered with 14%UV transparent plastic. The mushroom house was equipped with a microcontroller to monitor and control the room temperature and relative humidity. Twenty units of SHT22 sensor were installed to monitor the temperature and humidity; eighteen in the room, one above the ceiling, and the last was placed outside the house (above the roof). The system was equipped with 4 units of water sprayer heads to elevate the room humidity and decrease the room temperature. Two units of vents were installed at the upper wall to exhaust the room air when the humidity and temperature were above the optimum ranges. A unit of heater was added at the middle of the room to elevate the room temperature when it went down bellow 28oC. Results showed that when the temperature and humidity were not controlled, they could fluctuate out of the optimum ranges; temperature increased above 33oC and went down to 25oC. Likewise; humidity was ranging between about 50% to saturation. However; when the control was activated, the temperature and humidity were in general close to the optimum ranges.
