How To Build an Industrial Plants VOC Monitoring and Alarm Solution

Today, we’re going to share with you an 4G cellular modem-based VOC monitoring IoT solution of industrial plants and factories.

Before we talk about this solution, let’s take a look at some terms related to VOCs below.

  1. What are VOCs?

VOCs is short for Volatile Organic Compounds, which has high vapor pressure and low water solubility, are emitted as gases from certain solids or liquids.

  1. Producers of VOCs

Each day, there are tons of VOCs released from below sources, such as oil and gas production, industrial plants and factories, transportations-such as cars, motorcycles, buses, boats and airplane, gas stations, building materials like paints, and even from cooking.

  1. Why Shall We Care About VOCs?

VOCs can cause serious health effects both in short term and long term, such as headache, sneezing and runny nose, itchy eyes, skin irritation, as well as cause liver, blood damage and cancer, etc. In addition, it also causes harm to our environment, which also affects the plants of agriculture.

VOCs can cause serious health effects

As we discussed above, industrial plants are one of largest centralized source of VOCs, which has caused harm to our environment and threated people’s health. Therefore, the government and environment department are looking for a solution that can help them to remote monitor and record the level of VOCs from each plants and factories in industrial areas.

IoT Based VOCs Remote Monitor and Alarm System

The whole system includes 3 parts:

  1. Air ambient station that installed with VOCs sensor and meter, alarm light

These devices normally installed in a cabinet made by Aluminum and Stainless steel with IP6X rate, to measure the level of VOCs from industrial plants and factories. Besides, it comes with an alarm light on top of the cabinet, when the level VOCs surpass the preset alarm level, the light will blink.

How can we get the field data from remote sites?

  1. Bivocom Industrial cellular modem TD210 or TW810

In this case, since the meter and sensors are built in RS485 serial port, while the data is not big, so you can either use Bivocom TD210 series modems, which supports global 4G/3G/2G, and has RS232, RS485, built-in TCP/UDP, Modbus RTU/JSON/MQTT protocols. While if you have limited budget for modems, you can also use the cost-effective solution-TW810, an industrial LTE CAT M1/NB-IoT modem TW810.

Series TD210 TW810
Network 4G/3G/2G/CSD CAT-M1/NB-IoT/2G
Interfaces 1xRS232, 1xRS485
Data Transmission Transparent, or Modbus to Json*
Network Protocol TCP/UDP/MQTT*


How can we get the data displayed, analyzed and recorded at remote site? You need an IoT platform that either built on the cloud server or on-premise server.

  1. VOCs IoT Platform

There are at least 3 ways you can have your own IoT platform to monitor the data remotely.

  • Build your own private IoT platform based on mainstream IoT cloud suppliers if you have your own technical team, such as Microsoft Azue, Amazon AWS, Alibaba IoT Cloud.
  • Find a SaaS IoT platform and pay monthly fee

Bivocom has worked with global partners to certify its industrial cellular modems, routers, IoT gateways, RTUs with their IoT platform to offer the benefits to mutual customers, we’re happy to recommend our cooperated partners to you if needed. Below is a platform from one of our partners.
