1, traditional Hygrothermograph: because traditional Hygrothermograph all adopts expanding with heat and contract with cold of the materials such as mercury to represent the change of temperature and humidity, user waits the scale conscientiously must reading Hygrothermograph in use, the error of generation is comparatively large, and information is not easy to obtain;
2, independent electronics Hygrothermograph: the power consumption as fruit product in user's use procedure is excessive, the battery drain of Hygrothermograph in user's use procedure can be caused too fast, cannot continuous firing for a long time, use trouble, and layout affects indoor arrangement separately, affect attractive in appearance, thus bring great inconvenience to user;
3, similar products are used: if the precision of A/D converter is inadequate in user's use procedure, the data acquisition errors of two sensors then can be caused larger, easily cause the judgement of processor error, thus cause the temperature humidity information of user to open air well to determine;
4, similar products are used: if the humidity used in user's use procedure, temperature sensor precision are not high, the data acquisition errors of two sensors then can be caused larger, easily cause the judgement of processor error, thus cause the temperature humidity information of user to button position well to determine;
5, use similar products: if do not use transformer in user's use procedure, need to be equipped with one piece of battery separately, the work of Hygrothermograph long-time stable can not be ensured like this, comparatively bother and have a strong impact on work efficiency.
For this situation, the present invention uses, by temperature-humidity sensor, the humiture situation at keyswitch place place is fed back to user.User before use, first received in the wiring of 220V alternating current by 220V alternating current, reserve line and be connected with external connection electrical apparatus by external equipment, and by shell normal mounting on the wall, can normally use after installation; User can control the break-make of external connection electrical apparatus by switches button, meanwhile, 220V alternating current is converted to 5V alternating current by transformer, by obtaining stable direct current 5V voltage after rectifier circuit rectifies process for other circuit; Temperature sensor and humidity sensor receive the temperature humidity information at shell place place, digital signal is transferred to processor by A/D converter after finishing receiving, pass to LCD driver module after carrying out analytical calculation by processor, LCD driver module sends LCD display module to after obtained data being amplified; When user often through this system time just can be accurately real-time the humiture information obtaining this shell place place, not only seldom take volume, and relieve the problem of power supply.Solve the problem that people accurately cannot know occupied residence kind multiple position humiture situation in daily life.There is the feature of accuracy and real-time.
