INFRASENSING Digital Sound & Noise Level (dbA) Sensor User guide

  • Hello! I'm a chat assistant that has read the INFRASENSING Sensor Application Guide for ENV-NOISE, BASE-WIRED, and related accessories. This document provides information on installation, recommended sensor placement, and different power and connectivity options such as PoE, wired, and LoRa. I am ready to answer your questions about the sound sensor and its usage.
  • What does the ENV-NOISE sensor measure?
    How can the ENV-NOISE sensor be powered?
    Where should the noise level sensor be placed?
    How many sensor probes can be connected to the BASE-WIRED?

I. Overview
Our ENV-NOISE sensor measures sound and noise levels in its environment.
This document aims to guide the user in installing our ENV-NOISE in your facilities and also to provide
recommendations for sensor placement.
You may visit the sensor page through:
ENV-NOISE https://infrasensing.com/sensors/sensor_sound.asp
II. What you need
• Power source (PoE or 12V DC)
• BASE-WIRED
• LAN cable
• ENV-NOISE
III. Recommended sensor placement
OSHA provides guidelines where noise level sensors should be mounted:
• Required when noise levels can exceed 85dB
• Should be placed at the head level of the worker’s hearing zone at 20in /0.5m distance

IV. Installation
1.1. Supply power to the BASE-WIRED via PoE(power over ethernet or 12V DC adapter/BASE-PWR)
Other power options include BASE-PWR-USB, ADDON-POE, and ADDON-UPS.
1.2. Connect the BASE-WIRED to the sensor probe.
• Via direct LAN connection
You can connect up to 2 sensor probes to the BASE-WIRED
Revision 1 – June 7, 2022

• Via SensorHub(EXP-8HUB)
You can connect up to 8 sensor probes to the BASE-WIRED using the EXP-8HUB
• Via LoRa (EXP-LWHUB and NODE-LW-1P)
You can wirelessly connect your sensor probe to the BASE-WIRED, each LoRa hub can support up to 20
LoRa node. The LoRa Hub’s power is supplied by the BASE-WIRED while the LoRa Node’s power can be
supplied by 12/24V DC or a USB-C type.
