Development trend of temperature sensors
Mar 03, 2022|
View:43After entering the 21st century,Temperature SensorIt is developing rapidly towards high-tech directions such as high precision, multi-function, bus standardization, high reliability, high security, virtual sensors and network sensors, and single-chip temperature measurement systems.
1. Improve the accuracy and resolution of temperature measurement
EarlyTemperature Sensor, using 8-bit A/D converter, its temperature measurement accuracy is low, and the resolution can only reach 1 ° C. At present, foreign countries have developed a variety of high-speed, high-resolution temperature sensors. Using 9-12-bit A/D converter, the resolution can reach 0.5-0.0625 ° C.
2. Add test function
The test function of temperature sensors is also constantly being enhanced. For example, the ds1629 single-wire temperature sensor adds a real-time calendar clock (RTC-RRB- to make it more functional. The ds1624 also adds a storage function, using the 256-byte E2PROM memory inside the chip to store user short messages. In addition, temperature sensors are developing from single-channel to multi-channel, which creates good conditions for the development of multi-channel temperature measurement and control systems. The sensor has a variety of working modes to choose from, mainly including single conversion mode, continuous conversion mode, standby mode, and some have added a low temperature limit extension mode, which is very simple to operate.
3. Standardization and normalization of bus technology
Temperature SensorThe bus technology is standardized and normalized. The main buses used are single bus, I2C bus, SMBus and SPI bus.
