Security terminals are commonly deployed in harsh environments such as open-air factories, buildings and industrial sites. Interferences including drastic day-night temperature swings, high humidity, condensation and temperature drift will degrade imaging quality, detection accuracy and long-term device reliability. Accurate temperature & humidity sensing serves as the fundamental foundation for optical imaging, fire detection and infrared temperature measurement. Relying on its self-developed sensor product portfolio, GalaxyCore provides practical sensor chip solutions for typical security scenarios, supports domestic alternative sourcing and helps customers streamline hardware development.

Galaxy-CAS Chip was founded in 2018, focusing on the research and design of analog signal chain chips such as temperature, temperature and humidity sensors, storage authentication, interface circuits, signal conditioning, motor drive, clock chips, pressure sensors, current monitoring chips, etc. The company has always adhered to independent innovation, and all IPs are independently developed, achieving true independent controllability. At present, in the core product fields of temperature chips, temperature and humidity chips, single bus storage certification chips, interface circuit chips, etc., domestic substitution of some similar products from TI (Texas Instruments) and ADI (Yadno, including the original MAXIM brand) has been completed, and the performance indicators and reliability have reached the international equivalent level.

GXHT40 is a new generation single-chip integrated temperature and humidity sensor from Galaxy-CAS , which supports configurable I2C addresses and has a built-in heater that can be turned on (suitable for anti condensation scenarios, with configurable power). It adopts a 4-pin DFN package and breaks the record for domestic temperature and humidity sensors with an ultra small volume of 1.5 × 1.5 × 0.54mm ³, adapting to the standard SMT mounting process.

The analog chip industry has a unique development model, with many analog chip manufacturers adopting the IDM model. Among them, the top ten global analog chip manufacturers represented by TI and ADI are the most typical. Some manufacturers encounter the dilemma of "no quotation, no order" when preparing materials and placing orders. In this situation, domestic substitution has become imperative. Beijing Galaxy-CAS Technology Co., Ltd., as a cutting-edge enterprise focusing on the subdivision of analog signal chain chips, has achieved complete functional replacement of TI and ADI (MAXIM) related products in chip products such as temperature, humidity, single bus secure storage, and interface circuits.
