Whaaaat?!? How loud is it where you are right now? It can be quite challenging to find easily + rapidly deployable noise and environmental monitoring units. This summer, brothers Lorenzo & Edward from Valarm went to northern Pennsylvania to deploy Industrial IoT noise monitoring units measuring decibels (dB) around a natural gas compressor. We deployed 4 noise sensors for Seneca Resources at 4 corners surrounding a gas compressor station. At all 4 corners we deployed a Cirrus MK:427 noise sensor / outdoor microphone connected to a Valarm box, which you can see in the right part of the picture above. The box at 1 of the locations, a.k.a., the mother ship seen in the photo above, has all of these sensors:
- Meteo sensor (temperature, humidity, barometric pressure)
- Light sensor (lux / lumens)
- 4-20mA compatible wind direction sensor
- 4-20mA compatible wind speed sensor
- PWM compatible rainfall counter / sensor
- 4-20mA compatible noise / sound sensor / microphone
All of this sensor data is uploaded in real-time to Valarm Tools Cloud / tools.valarm.net, where the GIS & other teams at Seneca Resources use the remote sensor information for situational awareness and historical analysis. Using Valarm’s JSON API it’s easy for you to get your remote telemetry data into your business intelligence / analysis systems like the Esri ArcGIS platform. Below you can see an example of the remote sensor data in the Device Manager page of Valarm Tools Cloud – tools.valarm.net.
Inside of each of the remote sound / noise monitoring boxes (1 example seen above) you’ll see:
- Solar charge controller (connected to a solar panel above the box and a deep cycle marine battery under the box)
- Power over ethernet (PoE) adapter
- Ethernet sensor hub
- 4-20mA sensor adapter
- Yocto Relay (to send an occasional 5V pulse that automatically calibrates the noise sensor)
- 1 of the boxes has all of the additional weather and environmental sensors mentioned above and seen in the photos below
- Internet connectivity (via a Ubiquiti loco station M2 CPE or Mikrotik RouterBOARD SXT 2NDR2 CPE connected to a Sierra Wireless Verizon modem)
The main box with the noise microphone and weather sensors has a Sierra Wireless Verizon modem and shares that internet access via long-range WiFi using an outdoor ready Ubiquiti loco station M2 CPE. The other 3 Valarm boxes get internet access via long-range WiFi by connecting to the Ubiquiti router using their own Mikrotik RouterBOARD SXT 2NDR2 CPE – the circular antenna you’ll see in the box. It’s really easy and cost-effective to set up this long-distance WiFi network, which we’ll blog about more in a later blog post. Basically the Ubiquiti is a WiFi hot spot that gets internet through the Verizon cell network modem and the other Valarm monitors connect to the standard, shared Ubiquiti hot spot using Mikrotik WiFi antennas.
