Networked beer tanks from Keller The Internet of Things (IoT) always starts with a sensor. After all, things cannot capture states or carry out actions unless they are fitted with sensors. These two activities and a connection to the web are what make these objects ‘intelligent’ without the help of humans. This article describes how connected pressure sensors from Keller are being used to the delight of landlords and breweries. T he Internet of Things (IoT) offers smart solutions that help make life easier and more convenient. It can improve and streamline processes orderproposaltothelandlord,whosimplyhas to confirm the order. This automated, smart machine-to-ma- chine (M2M) solution reduces stress for land- lords and saves brewery drivers from prof- partner when it comes to implementing IoT solutions.

Smart solutions are highly personalised but always begin with an object and a sensor A level measurement with a remote trans- mitter is not just highly practical for detecting hazards but also for other level and fill level applications. Take pubs, for instance, where an emptying beer tank could be equally dangerous. In this application, two Keller pressure sensors work at the heart of the solution to measure the level of liquid in the tank and to send a warning message to the brewery by e-mail using an ARC 1 remote transmitter connected to the mobile phone network and the Internet.
