Introduction

The LoRa Tag LT100 Series is a wireless temperature and humidity sensor engineered for precise and centralized environmental monitoring across large-scale facilities. Functioning as a high-performance endpoint within a wireless ecosystem, the LT100 series LoRa data loggers utilize advanced LoRa technology to collect environmental data via its built-in sensors or an optional external probe, automatically transmitting readings to the cloud through GAEA series LoRa gateways.

This gateway-driven architecture grants users immediate 24/7 visibility via cloud platforms and mobile APPs, supplemented by open APIs for seamless integration into third-party enterprise networks. With its flexible installation methods, extended battery life, and robust local data protection, the LT100 Series LoRa data loggers serve as the ideal choice for scalable, automated environmental control in modern warehouses, laboratories, hospitals, and smart facilities.

Features

1. Optimize Large-Scale Deployment Costs

400m Long-Range LoRa Wireless Networking

Engineered with LoRa wireless communication, the LT100 Series delivers stable data transmission up to 400m in open air with strong signal penetration in dense indoor layouts. By allowing a single GAEA series gateway to centrally manage up to 50 LT100 Series LoRa data sensors simultaneously, this architecture eliminates complex wiring and excessive hardware infrastructure, making large-scale facility tracking highly cost-effective.

2. Adapt to Diverse Cold Chain Temperature Ranges

High-Accuracy Dual-Channel Monitoring

To accommodate the majority of cold chain temperature requirements, the LT100 Series LoRa data loggers feature built-in sensors delivering strict ±0.5°C accuracy for ambient environments (−30°C~+70°C). It also supports an optional external probe expansion to stretch monitoring limits from −90°C up to +200°C. All dual-channel readings automatically synchronize to the cloud via the GAEA gateway, allowing a single LT100 device to monitor deep freezers and ambient rooms simultaneously.

3. Ensure Uninterrupted Regulatory Compliance

100,000 Local Reading Buffer Prevents Data Loss

To prevent critical compliance gaps during network dropouts or signal blind spots, the LT100 Series is equipped with a 100,000-reading local memory buffer. The device automatically initiates localized offline logging the moment a network connection fails. Once wireless stability is restored, all cached data automatically synchronizes back to the cloud, guaranteeing an uncompromised audit trail for GxP and FDA inspections.

4. Minimize Financial Losses

Multi-Point Thresholds & Remote Real-Time Alerts

The LT100 Series real-time alarm sensors provide environmental threshold control by supporting up to 6 custom alarm points. The moment a temperature or humidity excursion occurs, the system triggers instantaneous, automated notifications via mobile App push, SMS, or email, allowing facility personnel to execute immediate risk mitigation before inventory is compromised and costly losses occur.

5. Drastically Reduce Routine Maintenance

1-Year Battery Lifespan via Low-Power Architecture

Powered by a 4000mAh rechargeable lithium battery and an energy-optimized firmware architecture, the LT100 Series achieves up to 1 full year of continuous operation on a standard 5-minute data upload interval. This extended operational lifespan slashes routine labor hours spent on frequent battery recharging or replacement across large-scale warehouse operations.

6. Empower Centralized Asset Management

Seamless IoT Platform & Third-Party Integration via API

Designed with an open and flexible software architecture, the LT100 Series IoT data loggers support comprehensive cloud-to-cloud and device-to-system integration through standard API protocols. This allows enterprise clients and system integrators to feed real-time temperature, humidity, and device status data into existing proprietary platforms via API services such as ERP, WMS, MES, or third-party industrial IoT solutions, eliminating data silos and enabling fully centralized environmental asset management.

Applications

The LoRa Tag LT100 Series wireless temperature and humidity sensor is optimized for targeted, multi-location monitoring, including:

  • Medical Refrigerators & Pharmacies: Real-time monitoring for highly sensitive vaccines and medicine storage.
  • Warehouse Racks & Aisles: High-density node deployment for spatial temperature monitoring.
