TSDT1-B | BLE Door and Temperature Sensor

In today’s logistics and cold chain industries, door and temperature status lost control will causes of cargo loss and insurance claims. From pharmaceuticals to fresh food and frozen goods, even a short temperature spike or unexpected door event can disrupt compliance and result in thousands of dollars in product waste.

The TSDT1-B BLE Door & Temperature Sensor was designed precisely to tackle these challenges.
Compact, wireless, and energy-efficient, it monitors both door status and ambient temperature in real time, transmitting data via Bluetooth Low Energy (BLE) to compatible asset trackers or BLE hubs. The data is then seamlessly delivered to cloud-based platforms for visibility, alerts, and reporting.

Unlike traditional wired sensors, the TSDT1-B requires no complex installation or maintenance — making it ideal for use on trailers, containers, reefers, and storage facilities where flexibility and scalability are key. Its BLE communication ensures stable performance and low power consumption, allowing years of operation on a single battery.

Why Door and Temperature Status Matter

In modern fleet and asset management, visibility equals control. Without live data on environmental conditions and door access, fleet operators are forced to rely on delayed reports or manual checks — a reactive approach that risks compliance breaches and shipment delays.

By integrating the TSDT1-B into your IoT ecosystem, you can:

• Detect door tampering or unauthorized access instantly.
• Track temperature trends to ensure cold chain compliance (HACCP, GDP).
• Reduce spoilage, theft, and insurance costs.
• Build a proactive monitoring system for asset protection and audit traceability.
