Noise

Sound-level sensing — machinery running, an alarm sounding, or activity where there should be silence. A microphone that reports a level, not a recording.

Sound is a surprisingly good sensor. The OGLAS Noise sensor reports a sound level — not a recording — so you can tell, from anywhere, whether something is running, alarming, or happening when it shouldn’t be.

What it does

  • Measures sound level — ambient dB over time, with thresholds you set.
  • Detects “running” — a pump, compressor, or generator is audibly on; pair that with Power Monitoring to confirm it’s working.
  • Detects “alarming” — another alarm sounding (a separate smoke alarm, a reversing beeper, a siren) becomes an OGLAS alert.
  • Detects “activity” — noise in a yard or shed that should be quiet overnight.

It reports a level and threshold crossings only — no audio leaves the device, which keeps it private and keeps the data tiny — see Your data is your data.

Hardware

A calibrated microphone and level circuit on an OGLAS node. Mains or battery; sited near the thing you want to listen to.

Pairs well with

  • Engine and Power Monitoring — “is it actually running?” from two angles.
  • Bell — turn a sound you can’t hear from the house into one you can.
  • Video — sound plus motion is a stronger “something’s happening” signal than either alone.
