For example, in the hot and humid summer months, people sweat a lot and are uncomfortable, and if their physical strength is exhausted, they may catch the so-called summer cold due to Adetsubium, which tends to breed in hot and humid conditions. In addition, in the low temperature and low humidity conditions of winter, the movement of the human nasal mucosa becomes weak, and influenza, which prefers low temperature and dry conditions, becomes prevalent.

〔Effect of the invention〕

The health information display device of the present invention performs arithmetic processing to compare information obtained by a temperature sensor and a humidity sensor with predetermined health information, and according to human health conditions stored in a ROM storage device according to a predetermined flow. Comparing with standard data, if certain conditions are met, it will be displayed on the display device, so the health information of that location can be recognized accurately and specifically, making it easy to perform accurate health management. . It should be noted that if the condition-specific reference data in the ROM storage device is set in more detail, health information can be recognized very accurately.

In addition, you can get accurate information about the location, rather than rough regional information like a weather forecast.Moreover, it displays specific warnings such as cold, dry weather, etc., so the location, house, Environmental measures and management can be carried out on a room-by-room basis.

Furthermore, in the device of the present invention, the time constant of the oscillation circuit changes according to resistance changes of the temperature sensor and humidity sensor interposed in the oscillation circuit, and the oscillation frequency changes without using an expensive analog-digital exchanger. Therefore, by adjusting the constants of the resistors and capacitors constituting the oscillation circuit and adjusting the oscillation frequency, temperature and humidity can be digitized at the optimal frequency for control. Further, there is no need for extra elements such as temperature compensation thermistors or logic gates.

As mentioned above, signals detected as frequencies are more resistant to internal and external noise than methods that detect potential differences or detect charging time of capacitive elements, and are especially
This is especially effective when a digital circuit including a CPU and a circuit including a sensor are mixed on one board.

Further, in the device of the present invention, a resistance circuit including each sensor is selectively interposed in the oscillation circuit, and is arranged in parallel with the active element constituting the oscillation circuit, and the active element is shared. A set of active elements can sense a wide variety of information from multiple sensors. Therefore, the circuit becomes simple, small and lightweight.

Furthermore, since the device of the present invention connects sensors one after another using a changeover switch,
Since the power consumption is low and the time during which the element itself is under load is short, there is an advantage that the life of the element is greatly improved.

In particular, there are many humidity sensors that are often used at high temperatures and have exposed elements that undergo significant deterioration over time.For such uses, the structure of the present application can significantly improve the lifespan of the element. The effect is large in this regard.

In addition, since the device of the present invention can measure temperature and humidity characteristics based on the difference in oscillation frequency, voltage fluctuations are small and the aging of the element is minute.
