As an important tool for obtaining information, the home temperature sensor plays an important role in fields such as family life. However, with the rapid development of microprocessor technology and the development of automation and intelligence in measurement and control systems, traditional sensors have been combined with various microprocessors and connected to the network to form information detection, signal processing, and logical thinking. Smart Home temperature sensor with a series of functions.
What are the advantages of the smart home control system under the Smart Home temperature sensor platform?
What is the method for Smart Home temperature sensor to improve temperature measurement accuracy and resolution?
Compared with traditional home temperature sensors, what are the advantages of Smart Home temperature sensor?
The response time of the smart home control system under the Smart Home temperature sensor platform is extremely short, and the sensing efficiency is high, which shortens the time delay caused by the propagation delay of the traditional controller, ensures the timeliness of the smart home control system, and improves the smart home The work efficiency of the control system truly realizes the fast and efficient smart home communication.
The first intelligent temperature sensor introduced in the mid-1990s uses an 8-bit A/D converter, which has low-temperature measurement accuracy and can only achieve a resolution of 1°C. At present, with the development of smart technology, foreign countries have successively introduced a variety of high-precision, high-resolution Smart Home temperature sensor, using 9-12 bit A/D converters, with a resolution generally up to 0.5~0.0625°C.
To improve the conversion rate of the Smart Home temperature sensor, some chips also use high-speed successive approximation A/D converters.
Traditional household temperature sensors, such as thermocouples, thermistors, and RTDS monitor temperature, have poor linearity in some temperature ranges and require cold junction compensation or lead compensation; the thermal inertia is large and the response time is slow. Smart Home temperature sensor has low power consumption; it can provide small package products; it can also achieve low device cost in some applications. In addition, since the Smart Home temperature sensor is calibrated during the production test, there is no need for further calibration. The newly developed Smart Home temperature sensor also adds a sensor fault detection function, which can automatically detect the open circuit or short circuit fault of the external transistor temperature sensor (also known as the remote sensor). Smart Home temperature sensor also has the option of "parasitic impedance cancellation" mode, which can offset the temperature measurement error caused by the load impedance of the remote sensor. Even if the lead impedance reaches 100 ohms, it will not affect the measurement accuracy. The lead wire of the remote temperature sensor of the smart home can use ordinary twisted pair or shielded twisted pair.
With the rapid development of science and technology, Smart Home temperature sensor continue to present new forms and advantages, which are increasingly in line with people's more diverse needs.
