ENV-AIRFLOWDigital Airflow Sensor Probe for data centers, server rooms & racks
Digital Airflow Sensor Probe for data centers, server rooms & racks
Digital measurement of air velocity, not a mechanical present/absent trigger.
Measures air speeds up to 3 m/s (6.7 mph / 10.8 km/h).
Reports actual velocity to the base unit, so thresholds can be set in software.
Probe design for mounting inside racks, ducts and containment aisles.
Powered by the base unit — no local power, no batteries.
Plug & play — SNMP, Modbus TCP, BACnet IP & MQTT ready.

Digital, Not Analog
Most airflow sensors for data centers report only whether air is moving, from a mechanical trigger. This one reports how fast.
Measures Air Velocity
Air speeds up to 3 m/s, equivalent to 6.7 mph or 10.8 km/h, reported in meters per second to the base unit.
Where It Is Used
Rack intake and exhaust, containment aisles, raised floor tiles and CRAC discharge — anywhere cooling depends on air actually moving.
Catch Degradation, Not Just Failure
A velocity reading trends downward as filters load and fans wear. A present/absent trigger only fires once the airflow has already stopped.
Mounting & Placement
Probe orientation, distance from the air source and why a consistent baseline matters more than an absolute figure.
How It Works
Connects to the base unit over standard network cable. The base unit is standalone, with no PC or software required.
Flexible Integration
Readings and alerts over SNMP GET & TRAPS, Modbus TCP, BACnet IP and MQTT for industrial IoT platforms.

Digital, Not Analog
Most airflow sensors currently available for data centers and server rooms are analog. They report only whether airflow is present, based on a mechanical trigger, with some units allowing the trigger level to be set by hand at install time.
ServersCheck introduced one of the first standalone digital airflow sensors for data centers. The probe measures airspeed in meters per second and reports that value to the base unit.
- A number, not a flag: you see the actual velocity, so you can tell a healthy 2.4 m/s from a struggling 0.9 m/s long before either becomes zero.
- Thresholds in software: alert levels are set on the base unit and changed at any time, rather than adjusted mechanically on site.
- Trendable: a continuous value can be graphed and compared against its own baseline. A trigger state cannot.
How It Works
The ENV-AIRFLOW connects to the base unit, which makes it an Ethernet sensor. The base unit is a standalone device with its own IP address in your network. On its own it monitors the sensor and triggers alerts via email, SNMP or optional SMS when needed.
There is no software or PC required for the sensor to run.
With our optional Monitoring Software you can centrally monitor sensors with trending and more. This is optional and not required.
Wired or Wireless
By default all sensors are connected to the SensorGateway (BASE-5) using a CAT6 or higher RJ45 cable.
Using the optional Wireless Hub & Node modules, any sensor can be turned into a wireless sensor.

RS485 (Modbus RTU) version
Looking to integrate this sensor with your own gateway or industrial control system? For large accounts customers or OEMs we now do offer a RS-485 version of this sensor. It has the same specs as the normal sensor. However rather than talking to our base unit and then communicate over industrial protocols with 3rd party systems, this version allows for native integration bypassing our base units.
It offers the same features as our regular sensors but with following differences:
- RS485 Modbus RTU output
- individually addressable using dial switch
- 256 addresses available
- 12-24v DC input
