Zhongke Yinhexin has successfully mass-produced high-precision temperature sensor chips GX18B20H and GX20MH01.

Understanding , Zhongke Yinhexin announced today that it has completed tens of millions of Pre-A round financing in July this year. The round of financing was led by the Chinese Academy of Sciences Venture Capital, Nanjing Dynamic Balance, Three Gorges Xintai, Beijing Kewei Venture Capital will jointly invest in technology research and development, product line expansion and mass production of some products, and further introduce high-end talents. Before, Zhongke Yinhexin was awarded the angel round financing of several million yuan of Zhongke Chuangxing in 2018.

Zhongke Galaxy is an entrepreneurial team from the Institute of Microelectronics of the Chinese Academy of Sciences. Its products cover temperature and humidity water sensor series, pressure sensor series, single bus chip series (mainly label chips) In three directions, the products include distributed temperature and humidity sensor chips, single-chip RFID+temperature chips, single-chip pressure sensors, and single-bus series chips. Applications include automotive electronics, industrial, smart manufacturing, communications, and the Internet of Things. With the basic structure of sensing unit + signal conditioning, the company’s core technology includes single-chip moisture temperature detection technology, high-precision temperature and humidity detection technology, wireless temperature measurement technology, sensor calibration technology, and large-scale temperature calibration test. Technology, etc., with software design capabilities, RF chip design capabilities, system development capabilities.

In the first half of this year, Zhongke Galaxy has successfully mass-produced high-precision temperature sensor chips GX18B20H and GX20MH01 with the highest precision of ±0.1°C, which can be widely used in medical electronics, drug storage, and high precision. Industrial measurement and other fields.

The temperature sensor chip with storage function GX20ME04 was successfully developed in the same period. The chip is a distributed temperature sensor chip with 1024B storage space. Each chip has a global unique 64-bit ID code. ; Each chip has 1024B of storage space for storing secondary calibration temperature information or user-defined information. When operating in the temperature calibration mode, it can be adjusted from -0.4375 °C to +0.4375 °C per 0.5 °C temperature range in the temperature range of 128 °C. The calibration step is 0.0625 °C, which can achieve the accuracy of 0.1 °C in the wide temperature range. . GX20ME04 can achieve a calibration accuracy of ±0.4°C in the range of -10°C to +70°C. The chip’s static standby power consumption is less than 1uA.

In addition, the moisture sensor chip developed by Zhongke Yinhexin has been developing applications in the fields of grain and soil, and started scale testing.
