Condition monitoring device

摘要

A monitoring device for monitoring treatment of the item. The device comprises a sensor for sensing a condition relating to the treatment of the item, a memory arranged to store sensor data, and a communication interface for generating a wireless signal for transmitting the data. The device further comprises a detector for detecting a predetermined event relating to the condition. The device is triggered to switch from a low power mode to a high power mode for a finite time period following detection of the predetermined event, and to switch from the high power mode to the low power mode upon expiry of the time period. In the high power mode the device is configured so as to read sensor data at an increased rate in order to gather sensor data or to send a communication signal at an increased rate for establishing a connection for transmitting data.
