Industrial control,environmental monitoring and intelligent equipment rely on the accuracy of temperature data,so the data acquisition of a temperature sensor IC with stable performance often determines the reliability of the whole system.This domestic GX30H05 introduced by Yingshang today,designed by Zhongke Yinhe Core,is a unique single-bus digital temperature sensor IC.
1.Characteristics of domestic high-performance 1-Wire temperature sensor IC GX30H05
GX30H05 adopts 1-Wire(single bus)communication protocol,and it only needs one signal wire and one ground wire to complete data interaction with the upper computer.This design greatly saves the pin resources of the microcontroller,and is especially suitable for situations where pins are tight or long-distance wiring is needed.The temperature sensor IC also supports parasitic power supply mode-power is directly obtained through the data line,and there is no need to connect additional power lines,which simplifies the difficulty of field wiring.A unique 64-bit serial number is solidified in each chip,so multiple GX30H05 can be mounted on the same single bus to realize a distributed temperature measurement network.A processor can easily manage dozens of temperature measuring points distributed in a large area.
2.Performance of domestic high-performance 1-Wire temperature sensor IC GX30H05
This temperature sensor IC has a wide temperature range of-80℃~+200℃,covering common industrial scenes from cryogenic to high temperature.In the temperature range of-10℃~85℃,the measurement accuracy can reach 0.5℃,which is enough to meet most precise temperature control requirements.The resolution of temperature sensor IC can be set to 9-bit,10-bit,11-bit or 12-bit by programming.At the highest resolution of 12-bit,the single temperature conversion time is less than 750ms,and the response speed is faster.Users can also use the on-chip nonvolatile memory to customize the upper and lower temperature alarm thresholds.Once the measured temperature exceeds the limit,the system can quickly locate the out-of-limit devices through the alarm search command-this function is particularly efficient in large-scale network inspection.
This domestic temperature sensor IC can not only complete communication and power supply with a single data line,but also support multi-point networking and programmable alarm,which is very suitable for HVAC environment control,building energy-saving monitoring,grain temperature measurement,industrial process control and other scenarios.If you are looking for a cost-effective,easy-to-use and reliable digital temperature measurement scheme,you can choose this high-performance 1-Wire temperature sensor IC.
