Galaxy-CAS "Ultra Micro Volume High Precision Wide Voltage" Temperature and Humidity Sensor GXHT40

Galaxy-CAS , in collaboration with EETC and EDNC dual platforms, has launched the "Chip Wednesday/Wed Chip Live" live streaming event simultaneously - compressing the selection cycle of multiple temperature and humidity sensors to the time of a cup of coffee, efficiently assisting engineers in precise selection. The core highlight of this live broadcast is the fourth generation new product GXHT40 of the Galaxy-CAS temperature and humidity sensor family.

GXHT40: Ultra compact size, fully upgraded performance

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.

At the same time, the product continues the high-performance genes of the product line:

Core parameters: Supports I2C interface (dual address optional), single bus interface, and analog output, with ultra-low power consumption of only 1uA; temperature typical accuracy ± 0.2 ℃, humidity typical accuracy ± 2% RH, communication speed up to 1MHz (resolution: 0.01% RH, 0.01 ℃), 1.6-5.5V wide voltage suitable for multi scene power supply;

• Working range: humidity 0~100% RH, temperature -40 ℃~125 ℃;

• Stable and reliable: Integrated temperature compensation and drift correction technology can resist errors caused by natural aging and environmental pollution for a long time, maintaining accuracy and consistency;

• Built in heater: automatically turns on the heating function when the ambient humidity is too high, and the power consumption is adjustable, effectively preventing condensation;

Flexible selection: Available in three forms: "without film, with dust-proof breathable film, and with three anti paint non permeable film", suitable for different application environments, reducing the difficulty for engineers to import.

Widely applicable scenarios

The intelligent temperature and humidity sensor IC can accurately measure temperature and humidity data in specific environments. In recent years, its application scenarios have continued to expand, and the market application of GXHT40 temperature and humidity sensor has rapidly expanded, covering multiple intelligent scenarios such as consumer electronics, smart homes, white goods, electricity, smart healthcare, wearable electronics, automobiles, and the Internet of Things.

At present, Galaxy-CAS  has four products GXHT30, GXHT31, GXHT30A, and GXHT31A that have passed the AEC-Q100 certification and are deeply applied in the automotive field
New energy battery pack: High humidity can cause battery aging and failure, and it is necessary to strictly monitor the humidity inside the battery pack.
Intelligent cockpit: The multi in one environmental sensor of the intelligent cockpit must provide a humidity sensor for environmental humidity control and VOC, carbon dioxide gas detection compensation. In addition, HVAC and rearview mirror defogging rely on humidity detection.
Rain sensor: detects raindrops on the front windshield, automatically activates the wipers based on the intensity of the raindrops, and dynamically adjusts the frequency of the wipers.
Air suspension system: The air suspension system strictly controls the humidity of the dry air inside, and needs to detect the humidity to prevent moisture from corroding the internal pipelines and ensure long-term operation.
Lidar: High humidity significantly reduces the laser detection distance, changes the refractive index of the air, and generates scattered interference signals. It is necessary to strictly control the humidity at a lower level. 04
