High-Precision Temp & Humidity Sensing
Equipped with an industrial-grade high-sensitivity sensor, it delivers accuracy down to ±0.2°C and ±2% RH. Supporting round-the-clock real-time monitoring, it can trigger threshold alerts when paired with the FeasyBeacon app. This provides reliable data assurance for high-sensitivity scenarios such as cold chain logistics and medical warehousing, effectively mitigating cargo damage risks.
Ultra-Low Power & Stable Transmission
Designed with a low-power Bluetooth architecture, the FSC-BP121 delivers up to 3 years of battery life under default settings while supporting stable BLE signal broadcasting for long-term continuous operation. Combined with its IP66-rated protection and slim form factor, it ensures reliable performance even in demanding environments.
Real-Time Sensing & Tracking
The FSC-BP121 temperature and humidity tag leverages low-power Bluetooth broadcasting and high-sensitivity sensing technology to continuously collect environmental temperature and humidity data while tracking item locations. It helps managers gain real-time insight into environmental conditions and cargo movements, mitigating dual risks of environmental anomalies and loss, effectively improving cold chain management efficiency.
