Abstract
The utility model discloses a household wireless outdoor temperature difference detection system comprising an indoor temperature measurement and display system (8) which is arranged inside a house, a first outdoor temperature detection system (4) which is arranged on an outdoo position exposed to the sun and connected with the indoor temperature measurement and display system (8) via a wireless transmission system, and a second outdoor temperature detection system (9) which is arranged on the outdoor position in the shade of the sun. The household wireless outdoor temperature difference detection system is simple in structure and low in cost. One-chip microcomputer technology is adopted as a control core and a DS18B20 chip is utilized to detect temperature respectively, and wireless data transmission is performed via an nrf24101 chip. Finally, indoor temperature, temperature of outdoor position exposed to the sun and temperature of outdoor position in the shade of the sun are displayed on a liquid crystal screen so that more accurate understanding of current temperature distribution situation by people is facilitated.
Description
Technical field
The utility model relates to the temperature sensing field, is specially the outdoor temperature difference detection system of a kind of household radio.
Background technology
In the northern area of China, winter temperature is on the low side, and temperature fluctuation round the clock is large, and indoor/outdoor temperature-difference is also very large.Even after sunrise, outdoor air temperature distribution is also unbalanced by day, the temperature under solar radiation usually, can be more high less than the temperature in place than sun lights.So often there will be outdoor sunlight to look nice, but real air temperature is very low; Or people feel heat when solar radiation, and situation about feeling a sense of cold while there is no sunlight.Therefore when people went out, if to the temperature misjudgment, wearing clothing may be on the high side or on the low side, made troubles so both for people's outdoor activity, also can be because of overheated or cold the healthy of people that affect of mistake.Especially under the environment of high residential building, when people's clothing is worn when improper, as returning to replacing, trouble not only, but also to delay a lot of times.
The Main Means that present people understand temperature is weather forecast, but relatively large deviation may appear in weather forecast, and can not provide the accurate data of instant temperature, more can not demonstrate the temperature difference situation of current outside air temperature.On the other hand, the outdoor section of existing outdoor thermometer is single-point and surveys, and only gathers more outdoor temperature, although can provide the temperature contrast of indoor and outdoor, difference that still can accurately ground reflection outdoor temperature.
Therefore how to understand the accurate situation of outside air temperature, grasp mxm. and the minimum of temperature, become the problem of the needs solution of people's living trip.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, it is a kind of simple in structure that the utility model provides, with low cost, take singlechip technology as control core, utilize the DS18B20 chip to survey respectively temperature, carry out Wireless Data Transmission by the nrf24l01 chip, indoor air temperature, outdoor area without shade temperature and outdoor shady spot temperature are presented on liquid crystal display the most at last, to be convenient for people to understanding comparatively exactly current air temperature distribution situation.
The purpose of this utility model is achieved in that
The outdoor temperature difference detection system of household radio, comprise and be arranged on indoor indoor thermometric and display system 8, and the first outdoor temperature detection system 4 that is arranged on outdoor area without shade that is connected by wireless transmitting system with indoor thermometric and display system 8, and be arranged on the second outdoor temperature detection system 9 of outdoor shady spot;
