Application of temperature and humidity sensor in smart home

2020-07-15 Source: admin
With the development of electronic technology, modern measurement technology has also developed rapidly, Temperature and humidity sensor Widely used in various fields. It is not only used in industry, mechanical equipment, machine room, warehouse logistics and other places, we are familiar with more is one of the accessories that often appear in smart home.

The working principle of the temperature and humidity sensor mostly takes the temperature and humidity integrated probe as the temperature measuring element. The sensor device which can be used to measure the temperature and humidity can be converted into the current signal or voltage signal output which has a linear relationship with the temperature and humidity after being processed by voltage stabilizing filter, operation amplification, nonlinear correction, V / I conversion, constant current and reverse protection circuit Through the main control chip for 485 or 232 interface output.

In general, it is difficult to install the sensor in the small temperature area due to the poor humidity. At the same time, there are many kinds of temperature and humidity sensors on the market, but most of the sensors can not timely transmit data to the monitoring center to regulate the measurement area, which brings some inconvenience to people's use; moreover, the measurement accuracy is not high, and the reliability is not high.

The design of wireless temperature and humidity sensor is very sensitive for space temperature control and humidity detection. It can intuitively feed back various monitoring data to users through wireless technology, so that users can know the current temperature and humidity of home or some environmental space, so as to improve the quality of life, it can let users adjust and control the corresponding environmental temperature on the basis of understanding the temperature and humidity Make it more conducive to human health.
