Data center sensing

Data Center Server Board Sensors

Board-level pressure, temperature, humidity and air-quality sensors for motherboards, GPU modules, power supplies, network switches and BMC applications.

Why it matters

Thermal management starts on the board.

GPUs, CPUs, VRMs and power supplies run close to their limits, and fan and pump control is only as good as the readings behind it. Board-level sensors let OEMs ramp cooling, throttle safely and flag condensation before it reaches the silicon.

What we monitor

CPU, GPU, VRM and PSU temperature
Chassis airflow ΔP for fan curves and blocked-intake alarms
Board-level humidity and condensation
