What Are The Advantages Of Smart Temperature Sensors?

The Internet of Things has become the development trend of information technology. Various smart devices will be used as the carrier of sensors to realize seamless interaction between people, machines and the cloud. Whether it is in health care, urban planning, or urban transportation, sensors are playing a core role. . The emergence of intelligent temperature and humidity sensors allows the functions of the sensors to be better exerted.

Temperature sensors are widely used in industrial and agricultural production, scientific research and life and other fields, and the number ranks first among various sensors. In the past 100 years, the development of temperature sensors has roughly gone through the following three stages: (1) traditional discrete temperature sensors (including sensitive components); (2) analog integrated temperature sensors/controllers; (3) intelligent temperature sensors. At present, new temperature sensors in the world are developing from analog to digital, from integration to intelligence and networking.

Smart temperature sensors all have a variety of working modes to choose from, mainly including single conversion mode, continuous conversion mode standby mode, and some have added low temperature limit extension mode, which is very easy to operate. For some intelligent temperature sensors, the host (external microcontroller or microcontroller) can also set its A/D conversion rate resolution and maximum conversion time through the corresponding registers.

The bus technology of the intelligent temperature sensor has also been standardized and standardized. The main buses used are single-wire (1-WIRE) bus, I2C bus, SMBUS bus and SPI bus. As a slave, the temperature sensor can communicate with the master through a dedicated bus interface.

With the development of intelligent sensor technology, the new generation of intelligent temperature sensor will continuously improve its functions by combining artificial neural network, artificial intelligence and other technologies, which can better monitor temperature and humidity, better serve us, and realize intelligent and standardization, which has brought great convenience to the production work and has a very considerable development prospect.
