Increasing demand for data processing and storage capacity has led to major companies investing in new facilities that provide web-based services to an ever-higher number of users. In these facilities, having the correct conditions – such as temperature and humidity – is vital for maintaining the equipment and securing operations.
The needs of colocation data centers, where space is rented out to multiple tenant companies, differ from those of hyperscale data centers with a single owner-occupier. While both require optimal atmospheric conditions to protect sensitive equipment and a reliable monitoring solution to control them, colocation data centers ideally need a modular setup to cope with changing customer requirements and shifting operational layouts.
Sensor chaining, also known as daisy chaining, is the perfect solution for colocation data centers. A sensor chaining solution consists of a cable running from a control panel down two data center aisles, with temperature and humidity probes attached via three-way splitters along the length.
The Vaisala sensor chain solution can be installed quickly and easily by a technician or facility manager with no need for a system integrator. With each probe taking just seconds to attach and no hard wiring, installation time and cost are significantly lower than traditional solutions.

The modular sensor solution for mission critical buildings
When reliability matters, measurements matter. Creating as-designed indoor conditions with minimized energy consumption requires precision and reliability at every piece of the chain.
Vaisala’s modular solution takes your measurement system to new levels of flexibility and productivity. To form a modular solution for critical buildings, you can choose between temperature and humidity transmitters with optional displays and miniature measurement probes. Transmitters and measurement probes are easily connected and chained using standard M12 or M8 connectors. Installation is made even easier with optional accessories, including magnetic probe attachment units and plug-and play cables of various lengths. What cannot be measured cannot be controlled. Vaisala is a global leader in environmental and industrial measurements. As the trusted provider of measurement instruments, we offer you peace of mind. You can rest assured that our measurement devices will enable the highest precision and reliability for your controlled processes, now and over the years to come.
