In fields such as industrial control, smart home, and medical equipment, the accurate collection of temperature and humidity data is crucial to ensuring stable equipment operation and enhancing user experience. A high-performance, highly adaptable temperature and humidity sensor is precisely the core component to achieve this goal.

Today, we are pleased to introduce the new-generation flagship product independently developed by Zhongke Yinhexin — the GXHT30C single-chip integrated temperature and humidity sensor. With its leading technological advantages and high reliability, it is becoming the preferred choice for environmental sensing solutions across various industries.

Core Highlight: Compact Size, Packed with "Precision and Efficiency"

Single-Chip Integration: Compact Yet Powerful

The GXHT30C directly integrates a high-sensitivity MEMS humidity sensor on a silicon-based CMOS wafer, adopting a miniaturized DFN package. With a size of only 2.5×2.5mm² and a height as low as 0.9mm — equivalent to 1/5 the size of a fingernail — it can be easily embedded in space-constrained devices such as smart bracelets, micro thermostats, and industrial switches, reducing the burden for product miniaturization design.

Full-Scenario Precise Sensing: More Reliable Data

No need to worry about environmental fluctuations affecting measurement results! The GXHT30C undergoes full temperature and humidity range calibration and temperature compensation before leaving the factory. Its typical humidity measurement accuracy reaches ±3% RH, and temperature accuracy is as low as ±0.3°C. Even in extreme temperatures of -45°C~130°C and a full humidity range of 0~100% RH, it can stably output accurate data. Equipped with a 16-bit high-precision ADC, it achieves a humidity resolution of 0.01% RH and a temperature resolution of 0.015°C, enabling precise capture of subtle environmental changes.

Wide Voltage + High-Speed Communication: Seamless Adaptation

With a wide supply voltage range of 2.5V~5.5V, the GXHT30C is compatible with both lithium battery-powered portable devices and standard power supplies for industrial equipment. It supports the I2C interface with a maximum communication speed of 1MHz, far exceeding the transmission efficiency of ordinary sensors. Additionally, it provides 2 user-selectable I2C addresses, allowing 2 sensors to share one I2C bus and simplifying circuit design.

Low Power Consumption + Long Lifespan: Lower Operation and Maintenance Costs

With a minimum measurement time of only 2.5ms and microampere-level current in idle mode, its average power consumption is merely 1.7μA (single conversion mode, 1 conversion per second), greatly extending device battery life. It boasts excellent long-term stability, with a humidity annual drift of <0.25% RH and a temperature annual drift of <0.03°C, reducing the hassle of frequent calibration and replacement and lowering long-term operation and maintenance costs.

Multi-Domain Adaptation: From Industry to Daily Life, a Versatile Solution for Every Scenario

Thanks to its comprehensive performance advantages, the GXHT30C has become a cross-industry "versatile environmental sensing expert," playing a crucial role in multiple key scenarios:

Industrial Control Field

Compatible with devices such as PLCs, industrial switches, and optical transceivers, it real-time monitors the temperature and humidity inside equipment in industrial environments ranging from -45°C to 130°C. It prevents circuit failures or signal interference caused by abnormal temperature and humidity, ensuring the stable operation of production lines.

Smart Home & Consumer Electronics

Embedded in products like smart thermostats, humidifiers, air purifiers, and smart bracelets, it accurately reflects the temperature and humidity indoors or around devices. It provides users with a comfortable living environment while enabling automatic device adjustment (e.g., automatically activating the dehumidification function when humidity exceeds the standard).

Medical Equipment Field

Applied in medical refrigerators, monitors, and other equipment, its high temperature measurement accuracy of ±0.3°C ensures data reliability in scenarios such as drug storage and patient temperature monitoring, complying with the strict standards for medical equipment.

Outdoor & Extreme Environment Equipment

Optional versions with dustproof and breathable membranes or three-proof (waterproof, dustproof, shockproof) paint films are available to resist harsh environmental impacts such as dust, corrosive gases, and high humidity. It is suitable for scenarios like outdoor weather stations and online monitoring of new energy storage batteries, enhancing the sensor’s reliability in complex environments.

Core Value: Fortify the Foundation of Domestic Sensors Through Technological Innovation

The GXHT30C has not only passed RoHS environmental certification and complies with the JEDEC J-STD-020 Moisture Sensitivity Level 1 standard but also strictly adheres to the JEDEC JESD47 quality inspection standards during the production process. Every step from design to delivery undergoes rigorous control, ensuring that each sensor delivered to customers boasts stable and reliable performance.

Currently, the GXHT30 is available in tape and reel packaging (minimum packaging of 2000 units), and three variants are launched for different scenarios: the Basic Version (GXHT30-T&R), the Dustproof & Breathable Membrane Version (GXHT30-T&R C), and the Conformal Coating-Compatible Version (GXHT30-T&R CF), meeting diverse customer needs.

Take Action Now: Unlock a New Experience of Precise Environmental Sensing
