Abstract

This work presents the effects that ambient temperature causes on the SL900A sensor tag’s current consumption. Temperature conditions inside a metallic tray, transporting ready meal for the service food industry, are replicated through a climatic chamber whereas the current consumption is measured using a DC power analyser. Both active and data logging modes of operation have been used and the correlation between their current consumption and the temperature variation has been analysed.

Highlights

  • In recent years, the sector of catering services has increased the number of contracts up to 33%of firms or collective organizations in the EU

  • Whereas the conductivity at zero temperature would vanish, it rises together with the temperature, so an analysis on this effect to anticipate system autonomy issues is recommended

  • It is capable of operate in fully passive mode, it operates in semi-passive mode which makes it ideal for data logging applications

Summary

Introduction

The sector of catering services has increased the number of contracts up to 33%. Beretta et al have pointed out that the 12.5% of the losses in the food service industry are avoidable whereas 1% might be catalogued as possible avoidable losses and the 4.5% are not avoidable [8] Such avoidable losses cannot be accepted and entities such as the Food and Agriculture Organization of the United Nations (FAO) and the European Parliament (EP) have already launched several policies and initiatives [9,10]. Following to these efforts, temperature control has come up as a key factor in the distribution sector of the whole food supply chain.
