Because temperature distribution in house is uniform, it won’t affect the uniformity of the crop inhabitants progress. We put in several sensors in greenhouse together with air temperature, relative humidity, soil temperature, radiation (or gentle intensity), crop digital camera platform with synchronization images, which composed the sensing layer of IOT. At the same time, the appliance platform triggers clever switch through SMS to start out the heating equipment, link after which prevents the crop from low-temperature catastrophe. This study successfully solved the low-temperature catastrophe monitoring and early warning drawback in Tianjin. Most applications focus on amenities fashionable greenhouse environment monitoring and regulation, product traceability, and pest distant diagnostics. As a result of most greenhouses share a few structures, when we make a low temperature catastrophe warning towards one sort’s construction, it may be despatched to the greenhouse manager group who owned similar type greenhouse construction. We developed skilled weather service webpage for actual-time knowledge and image display, microclimate data evaluation and disaster warning within the greenhouse. Utilizing Internet of Things and cloud computing know-how, it helped users to amass relevant data via easy receiving terminal that could possibly be used for catastrophe prevention.
