Wireless temperature and humidity monitoring solution
16 December 2014
Monitoring temperature and humidity is important in many applications. However, too often, this vital data is manually collected at infrequent intervals which is not a suitable solution in situations that rely on stable temperature management to ensure product consistency.
Traditionally, there have been two methods available for monitoring irregular fluctuations in temperature and humidity – data loggers and data monitoring systems. Data loggers offer a simple solution but because the data needs to be acquired manually this technique does not always inform users of temperature fluctuations. The alternative, data monitoring systems can be complex and time consuming to install.
Testo has introduced a cloud-based wireless temperature and humidity monitoring solution which offers an automated, continuous monitoring solution. The Saveris 2 allows users to keep track of temperature and humidity levels remotely, without the need for software.
The use of cloud-based technology stores the data remotely, yet enables access to this data from anywhere, whenever it is needed. If temperature or humidity levels fluctuate beyond acceptable levels an alert can be sent by SMS and e-mail to responsible parties’ responsible, allowing appropriate action to be taken in a timely manner.
The measurement values are automatically and securely transmitted to the Cloud via wireless LAN, so manual readout of the wifi data logger is not required, eliminating recording errors.
Data is accessed simply by logging on to the secure cloud location which requires just a standard internet browser – so can be accessed via a PC or smart mobile equipment. If monitoring on site, Saveris 2 can scan the logger’s built-in individual QR code, which will take the user to the individual logger’s secure cloud page.
Using their vast experience with temperature logging, Testo was aware many of their customers’ businesses expand and change over the life of a product. So the Saveris 2 system has been designed with flexible expansion capabilities with customers able to start with a simple setup which can be added to over time and making it easy for the system to grow as their business develops.
There are five different temperature and humidity probes available in the Saveris 2 range and there is an option three licensing models for the use of the Cloud service. The devices are available with sensors that are either integrated into the monitoring device or are external so can be positioned remotely to the monitoring device. There are a variety of sensing probes available for the system to allow it to be employed in a wide range of application scenarios.
