Introduction

The LoRa Tag LT100 Series is designed as a low-power wireless temperature and humidity logger for centralized environmental tracking in large facilities. Equipped with built-in high-accuracy sensors and an optional external probe socket, the LT100 series LoRa data sensor uploads real-time environmental data to cloud systems via GAEA series LoRa gateways. This architecture allows users to view live climate data 24/7 on cloud dashboards and mobile applications, with open APIs available for third-party platform connection. Offering easy installation, long battery life, and local reading protection, the LT100 series wireless LoRa data logger is a scalable solution for automated environment control in modern warehouses, laboratories, hospitals, and smart facilities.

Features

1.Slash Infrastructure and Hardware Overhead

400m Long-Range LoRa Connectivity

Buil on the high-efficiency LoRa protocol, the LT100 series wireless LoRa data logger delivers reliable data paths across 400m open areas and easily penetrates dense physical barriers inside industrial buildings. Because a single GAEA series wireless gateway can handle data from up to 50 concurrent LT100 sensors, companies can monitor entire facilities without expensive hardwiring projects or additional network hardware.


2.Cover Extensive Cold Storage Conditions

Dual-Probe Temperature and Humidity Coverage

Configured to handle almost any commercial storage temperature, the LT100 series LoRa data sensor relies on a premium built-in sensor to maintain tight ±0.5C accuracy across standard ambient settings (-30℃ ~ +70℃). When applications demand specialized ranges, adding an optional external probe extends the LT100 operating limits down to -90℃ and up to +200℃, allowing users to deploy a single device for concurrent monitoring in deep freezers and ambient zones.


3.Safeguard Critical Audit Trails

Onboard 3,000-Point Backup Buffer Against Signal Blindspots

To keep your data records completely gap-free during sudden network drops or wireless blind spots, each LT100 series LoRa data sensor includes an internal 3,000 reading memory buffer. If the gateway connection drops, the LT100 immediately transitions to local offline logging mode. The moment the wireless link is re-established, all buffered temperature data history uploads automatically to the cloud platform, delivering the continuous data verification required by FDA and GxP compliance officers.


4.Prevent Product Waste and Damage

Custom Alarm Settings with Automated Multi-Channel Notifications

The LT100 series moves beyond passive logging by offering active inventory safety through 6 fully customizable alert thresholds. If a temperature or humidity variance breaches set limits, the system immediately pushes automated alarms via mobile app notifications, direct SMS text, or email, allowing on-site staff to correct cold chain errors before high-value stock suffers financial write-offs.


5.Minimize Ongoing Operational Upkeep

Year-Long Lifespan via Optimized Battery Firmware

Equipped with a high-capacity 4000mAh rechargeable lithium cell and smart power management firmware, the LT100 series LoRa data logger functions continuously for up to 12 months using standard 5-minute reporting intervals. This extended field performance means facility technicians spend significantly fewer labor hours dealing with frequent LT100 recharges or battery swaps in large-scale storage spaces.


6. Facilitate Enterprise System Integration

Flexible Third-Party Platform Connection via API Service

The LT100 series LoRa temperature data logger allows smooth cloud-to-cloud and device-to-system data streaming using API connections. Through these API services, business users and system integrators can automatically import real-time temperature, humidity, and operational status data straight into their current management platforms, including ERP, WMS, MES, or alternative industrial IoT software, removing information barriers and ensuring centralized environmental asset monitoring.

Applications

The LoRa Tag LT100 Series wireless temperature and humidity logger provides specialized, distributed tracking for:

Clinical Cold Storage & Medicine Facilities: Constant supervision for critical biologicals and vaccines.

Industrial Warehouses & Distribution Aisles: Multipoint placement for spatial climate analysis.

Research Labs & Environmental Cleanrooms: High-precision environmental validation.

Smart Facilities & Automated HVAC Systems: Distributed sensor feedback for centralized temperature management.
