thermography in this application space, developing a prototype that proved the concept. Its technology has since been confi rmed by clinical trials and Avnet worked with Braster and its chosen design partner to move from a prototype solution to a production- ready version of the system.
Food Transportation
Both the United States and the European Union have regulations related to the safe transport of food, which rely predominantly on monitoring the temperature of the containers used both before and during transportation. These are, respectively, the Food Safety Modernisation Act (FSMA) and EN12830.
The data loggers used to record the temperature of food storage and transport containers are becoming more ‘connected’ thanks to the Internet of Things. It means that temperature loggers can automatically relay their readings to cloud-based platforms, wirelessly and potentially more often, to not only meet legislative requirements but also to provide a competitive advantage. It could see companies offering more ‘forensic’ data that goes beyond the bare minimum required by law.
The combination of temperature monitoring and activity logging is giving rise to a new class of smart device that provides multiple functions. Legislation is, again, driving demand for these types of solutions, underpinned by a need for greater safety at all levels.
Advanced Temperature Sensors
As mentioned above, semiconductor junctions provide an excellent way of measuring temperature and because they are based on standard IC manufacturing processes they can be made physically much smaller than their passive counterparts. This has advantages in today’s electronic products that are typically smaller with every new generation but still need to include temperature- monitoring features.
The TSYS02D Digital Temperature Sensor from TE Connectivity is a perfect example. It offers 16 bit resolution across a temperature range of -40°C to +125°C with a resolution of 0.01°C, accessed through an industry standard I2
C
interface and supplied in a TDFN8 package.
