Vaisala launches Indigo Supervisor for data centre sensors

Vaisala has launched Indigo Supervisor for modular sensor networks in data centres, designed to let operators manage up to 100 measurement points as a single system.

The product targets an area of data centre operations that is growing more complex as facilities expand to support heavier AI-related computing loads and denser equipment layouts.

Indigo Supervisor is a host unit for the company's daisy-chained compact measurement probes, a format intended to reduce cabling at sites that use large numbers of sensors. In data centres, those sensors are used across data halls, technical spaces, support areas and other locations where operators need environmental readings.

The new unit supports up to two independent probe chains, with as many as 50 probes on each. It can be managed through a local touchscreen interface and connected to a building management system through a single standardised Modbus TCP connection.

This marks a shift from managing environmental monitoring sensor by sensor to running broader measurement networks as a single system. That becomes more important as operators deploy monitoring across larger estates without adding installation and maintenance burdens.

Environmental monitoring in data centres typically covers factors such as temperature and humidity, which affect equipment conditions and day-to-day operations. As sites scale, the issue is no longer only whether coverage exists, but whether networks can be installed, commissioned and maintained across many points without slowing projects or disrupting live facilities.

Operational shift

The system includes local dashboards, measurement visibility, alert management and calibration information. It also supports commissioning through web-based tools, while system configuration can be exported as CSV files for commissioning work and use across multiple sites.

The touchscreen interface can also be used for probe replacement, which matters in facilities where access and service windows are tightly controlled. Standardising these tasks can help operators reduce variation between rooms, halls and separate buildings.

The unit is compatible with Vaisala XMP10, HMP110, HMP113 and TMP115 probes. By combining those probes within chained networks, Vaisala is targeting sites where environmental data is collected at many individual points but handled through a smaller number of management interfaces.

The product also reflects a broader move in data centre infrastructure towards modular systems that can be repeated across projects. Operators are under pressure to add capacity quickly, particularly where AI workloads require more power and cooling support, and the supporting infrastructure is expected to keep pace.

Anu Kätkä, Product Line Manager for HVAC and Critical Buildings at Vaisala, said changes in data centre construction and operation are altering what operators need from monitoring systems.

"AI is accelerating data centre growth at a pace that is changing how supporting infrastructure is deployed, managed and scaled," said Anu Kätkä, Product Line Manager for HVAC and Critical Buildings at Vaisala.

"When a facility contains dozens or hundreds of measurement points, environmental monitoring can no longer be managed one sensor at a time. Operators need a system-level approach to environmental monitoring that can be commissioned efficiently, maintained without disrupting operations and scaled consistently as capacity expands," Kätkä said.

Beyond data centres

Although the launch is focused on data centres, the unit can also be used in other settings where many sensing locations need to be monitored in an organised way. These include cleanrooms, greenhouses, cold storage facilities, laboratories and industrial process environments.

That gives the product a role in sectors where operators face similar issues around repeatable deployment, maintenance access and integration with existing management systems. In each case, the emphasis is on reducing the number of separate elements staff need to configure and oversee.

Indigo Supervisor is expected to be available in early 2027.
