Cooling and/or freezing apparatus has a sensor for detecting parameter value comprising data related to different characteristics of apparatus, which is transferred to a receiver in wireless, optical or acoustic manner

摘要

The cooling and/or freezing apparatus comprises a sensor for detecting a parameter value comprising data related to the temperature, humidity, amount of light used, energy consumption level, etc., of the apparatus, which is transferred to a receiver in wireless, optical or acoustic manner. The sensor has an independent energy source which is designed such that it contributes to the supply of locally available energy including solar energy, kinetic energy, electro-dynamic energy or light energy, for the operation of sensor.
