The integrated sensor is made of silicon semiconductor integration process, so it is also called silicon sensor or monolithic integrated temperature sensor. Analog integrated temperature sensor came out in the 1980s. It is a special IC that integrates the temperature sensor on one chip and can complete the functions of temperature measurement and analog signal output. The main characteristics of analog integrated temperature sensor are single function (only measuring temperature), small temperature measurement error, low price, fast response speed, long transmission distance, small volume and micro power consumption. It is suitable for long-distance temperature measurement and control without nonlinear calibration and simple peripheral circuit. It is the most widely used integrated sensor at home and abroad. Typical products include AD590, AD592, tmp17, LM135 and so on.
Analog integrated temperature controller mainly includes temperature control switch and programmable temperature controller. Typical products include LM56, ad22105 and max6509. Some enhanced integrated temperature controllers (such as tc652 / 653) also include a / D converters and cured programs, which are similar to intelligent temperature sensors. However, it has its own system and is not controlled by the microprocessor, which is the main difference between the two.
Intelligent temperature sensor (also known as digital temperature sensor) came out in the mid-1990s. It is the crystallization of microelectronics technology, computer technology and automatic test technology (ATE). At present, a variety of intelligent temperature sensor series products have been developed in the world. The intelligent temperature sensor contains temperature sensor, a / D converter, signal processor, memory (or register) and interface circuit. Some products also have multiplexers, central controller (CPU), random access memory (RAM) and read only memory (ROM). The characteristic of intelligent temperature sensor is that it can output temperature data and related temperature control quantity, and adapt to various microcontrollers (MCU); And it realizes the test function through software on the basis of hardware, and its intelligence also depends on the development level of software.
new development trend of intelligent temperature sensor
After entering the 21st century, intelligent temperature sensors are developing rapidly in the direction of high-tech, such as high precision, multi-function, bus standardization, high reliability and security, the development of virtual sensors and network sensors, and the development of single-chip temperature measurement system.

The intelligent temperature sensor first launched in the mid-1990s uses an 8-bit A / D converter. Its temperature measurement accuracy is low and its resolution can only reach 1 ℃. At present, many kinds of intelligent temperature sensors with high precision and high resolution have been launched abroad. The 9 ~ 12 bit a / D converter is used, and the resolution is generally up to 0.5 ~ ℃. DS1624 high resolution intelligent temperature sensor newly developed by Dallas Semiconductor Company of the United States can output 13 bit binary data. Its resolution is as high as ℃, and the temperature measurement accuracy is ± 0.2 ℃. In order to improve the conversion rate of multi-channel intelligent temperature sensor, some chips use high-speed successive approximation A / D converter. Taking ad7817 5-channel intelligent temperature sensor as an example, its conversion time to local sensor and each remote sensor is only 27 minutes respectively μ s、9 μ s。The test function of the new intelligent temperature sensor is also continuously enhanced. For example, ds1629 single wire intelligent temperature sensor adds real-time calendar clock (RTC) to make its function more perfect. DS1624 also adds a storage function, which uses the 256 byte E2PROM memory inside the chip to store the user's short message. In addition, the intelligent temperature sensor is developing from single channel to multi-channel, which creates good conditions for the research and development of multi-channel temperature measurement and control system.
