⚠️ TSDT1-B is transitioning to the next-generation product: T-sense. T-sense enables richer condition monitoring for cold chain logistics.
TSDT1-B
BLE 5.0 Door & Temperature Sensor
TSDT1-B is a dedicated door sensor designed to detect open and close events within vehicle and asset tracking systems. It provides basic door status monitoring for security and logistics visibility, serving as a straightforward solution for entry event detection.
It monitors the door status and temperature of the environment. TSDT1-B broadcasts the data
via BLE to be picked up by trackers or BLE hub and transmitted to server eventually, and it is also designed in response to industry demands for environment monitoring to resolve losses
caused by unexpected changes of temperature and truck door status.
