Xiamen Trust Information Tech Co., Ltd.

Xiamen Trust  is a national-level high-tech enterprise, a Xiamen "Specialized, Sophisticated, Distinctive and Innovative"  company, and a dual-software certified enterprise. Founded in 2004 and headquartered in Xiamen, Fujian Province, the company focuses on the R&D, production, and service of IoT wireless sensor solutions. Its products center on wireless LoRa low-power sensors, covering monitoring of multiple environmental parameters including temperature, humidity, carbon dioxide (CO2), oxygen (O2), volatile organic compounds (VOCs), formaldehyde (HCHO), PM2.5, partial discharge, as well as security sensors for equipment rooms such as door magnetic sensors, water immersion detectors, and smoke detectors. It has become one of the most influential brands in the domestic wireless sensor field.

I. Twenty Years of Deep Cultivation - Technology Builds Core Competitiveness

From the day it was established, Xiamen Trust has taken "Making Perception of Everything Simpler and More Reliable" as its corporate mission. After more than a decade of technological accumulation and market validation, the company has formed three core technical advantages: **ultra-low power consumption design + industrial-grade reliability + ultra-long-distance LoRa communication**.

- Independently developed LoRa low-power sensors achieve a battery life of up to **more than 3 years**.

- Anti-interference capability improved by **over 30%**, with stable communication distance reaching **500 meters** (line-of-sight in star topology) even in complex environments.

These hard-core performance indicators enable the sensors to maintain extremely high stability and data accuracy in harsh scenarios such as extreme temperature and humidity, strong interference, and shielding.

The company achieves full-process control from product functional testing to finished product aging, ensuring every sensor shipped meets industrial-grade quality standards. It has obtained authoritative certifications including **ISO9001** Quality Management System, **ISO14001** Environmental Management System, **ISO45001** Occupational Health and Safety Management System, Intellectual Property Management System, and **ISO27001** Information Security Management System.

 II. Rich Product Matrix Covering Essential Scenarios Across Multiple Industries

1. **Temperature & Humidity Sensor Series**: ±0.3ºC high-precision temperature and integrated temperature-humidity sensors, widely used in highly regulated scenarios such as pharmaceutical cold chain, blood banks, CDC disease control centers, and biological sample repositories.

2. **Gas Sensor Series**: Multi-principle (electrochemical/infrared/semiconductor) sensors for CO2, O2, HCHO, VOCs, CO, H2S, NH3, etc., meeting the air quality requirements of sensitive locations like archives, museums, and clean rooms.

3. **Particulate Matter Sensor Series**: Laser scattering PM2.5/PM10 sensors applied in air quality monitoring for smart campuses, hospitals, schools, office buildings, and other public facilities.

4. **Power & Equipment Room Environmental Monitoring Series**: Security sensors including door magnetic, water immersion, smoke, and infrared intrusion detectors. Combined with the EMS-2600 host, they provide low-cost power and environmental monitoring and early warning for small and medium-sized equipment rooms and weak-current rooms.

5. **Industry-Specific Customized Series**: Integrated solutions tailored for special needs in industries such as tobacco, grain, and power, e. g., multi-parameter monitoring (temperature, humidity + CO2 + oxygen) for tobacco aging warehouses, and online partial discharge monitoring systems for switchgear cabinets.

All products have obtained national metrology verification reports, **EU CE-RED**, **RoHS**, **US FCC ID**, **Japan TELEC (MIC)**, and other certifications, truly achieving "develop once, sell globally. "
