Indoor CO₂ Air Monitoring Solution for LoRaWAN®

Overview

School A, located in a busy city center, is grappling with elevated indoor carbon dioxide (CO₂) levels - a silent issue adversely impacting students' health and concentration. Although CO₂ is generally harmless at low concentrations, high levels signal poor indoor air quality and a buildup of other harmful pollutants. Current solutions have proven costly and ineffective. Therefore, the school urgently seeks a real-time CO₂ monitoring system. This initiative could greatly boost student well-being and focus, while also reducing the risks tied to variable air quality. It's a step towards ensuring a consistently safe and productive learning space amidst the urban hustle.

Problem

High levels of CO₂ can cause health problems and discomfort for occupants. Regulations require better ventilation in enclosed spaces, such as classrooms and school facilities, but implementing effective IoT solutions for CO₂ monitoring is challenging.

School A is facing difficulties in making sure that its coverage is complete, methods are cost-effective, and systems are easy to install and maintain. These challenges are made more difficult because the school is located in an urban area, where polluted air can easily enter the building. This means that finding a solution to these problems will require a sophisticated and practical approach.

Use Case

In response to the need for a safe and healthy learning environment, School A adopted the Qingping LoRaWAN® CO₂ Monitoring Sensor.

Picture a classroom or teacher’s lounge where unobtrusive devices efficiently monitor air quality. These power-efficient devices cover the school's large premises, including areas with potential signal blockages.

The system is easy to install and manage. In case of interference, devices automatically switch to backup channels, ensuring reliable performance. The network's star topology simplifies operations and manages bandwidth.

This strategic move by School A has effectively addressed the problem of indoor air quality, enhancing student health and focus through technology.

Benefits

Efficient Energy Use: The low power consumption of the LoRaWAN devices ensures they can operate for extended periods without needing frequent recharging or replacement.

Long-Range Capabilities: The system can transmit data over vast distances, making it suitable even in indoor environments with potential wireless signal obstructions.

Affordability: Compared to other wireless technologies, LoRaWAN devices are generally less expensive, offering a cost-effective solution.

Ease of Deployment: The simplicity of setting up and managing the LoRaWAN network reduces the hassle associated with network management.

Reliability: With their high reliability and ability to switch to backup channels if interference is detected, LoRaWAN devices ensure consistent performance.

Improved Return on Investment: The deployment of a LoRaWAN network not only addresses the immediate needs of the school but also enhances the return on investment over time by reducing operational costs and improving overall efficiency.

Success Factors

Whether you're a solution reseller or a solution integrator, here’s how you can convince network users and end-users to adopt this use case through project experience:

Constructing a Prototype: Initiate a pilot project involving three CO₂ sensors and an indoor LoRaWAN gateway. A prototype can aid regulators in grasping the advantages of the solution.

Establishing CO₂ Concentration Standards: Work together with local authorities to determine permissible CO₂ concentration levels and set rules for preserving air quality.

Partnering with Major BMS Providers: To expand this solution to schools or buildings, think about partnering with prominent Building Management System (BMS) providers via protocols such as Bacnet or MQTT
