- Exhaust the impurity air
- Colleagues breathe smoother and work smoother
- Easily manage the indoor environment
Background
Hong Kong is geographically close to factories in the Mainland, and the pollutants produced by them are blown to Hong Kong by the northeast wind, making Hong Kong’s air pollution increasingly serious. The dense buildings in the urban area also make it difficult to spread suspended particles and fine dust in the air. The screen building obstructs air circulation, and air pollution will become more and more serious. Under the vicious circle, indoor dust will not be scattered.
Existing Problems
Hong Kong’s air pollution, outdoor, industrial exhaust gas and automobile exhaust from transportation.; and volatile organic compounds (VOCs) commonly used in the interior decoration process are difficult to disperse in the general indoor environment, which seriously affects human health.
The hazards of volatile organic compounds are obvious. When the concentration exceeds a certain level, people will feel headaches, nausea, vomiting and weakness in the limbs quickly. In severe cases, they may experience convulsions, coma, and memory loss. Volatile organic compounds can damage the liver, kidneys, brain and nervous system of the human body and contain many carcinogens. The pollution of indoor air caused by volatile organic compounds has aroused the concern of various enterprises.
Solution
We have a set of IoT monitoring solutions for indoor environment management. Install the corresponding wireless sensors to manage indoor air quality.
IoT technology LORAWAN – Thousands or even tens of thousands of node capacity connect easily
LoRaWan is a wireless communication technology designed to create low-power wide-area networks (LPWAN) required for machine-to-machine (M2M) and Internet of Things (IoT) applications. The information can be sent to any base station connected to the cloud platform at low cost, low power consumption, safety, and long-distance.
Management system optimization & Powerful back-end
There are four other functions in the back-end:
- Multi-identity login interface: hierarchical access
- Data visualization chart: Data will be displayed in various chart, such as column chart, bar chart, line chart, pie chart.
- Instant data transmission: transfer messages in real-time via LoRaWan, Json, MQTT communication protocols
- Complete data export
TVOC air quality sensing device
It can monitor the air quality in real-time, transmit information flexibly, automatically activate the ventilation system, inhale the fresh air, and remove the impurity air in the room to improve the indoor air quality.
Laser dust sensing device
- Laser scattering technology
- Real-time information transmission
The laser dust sensing device can distinguish the indoor dust content with laser technology, flexibly transmit information, automatically activate the ventilation system, inhale the fresh air, and exhaust the impurity air in the room to improve the indoor air quality.
Conclusion
In addition to effective management of the indoor environment, effective air quality is also very important to colleagues’ health. The air in the work environment is of good quality. When colleagues breathe smoothly, they work smoother. Ensure that the indoor climate changes, the product is protected by the indoor sensor device and will not be affected. Managers can record the indoor air quality through the management system or application and keep the air quality at a preset degree in the monitoring room. LoRaWan will transmit the data to the cloud background and immediately issue an alarm to notify the management personnel whether the air quality exceeds the allowable upper limit and promptly initiate preset countermeasures to maintain normal indoor air quality. To ensure that the indoor environment is normal, companies can also foresee problems and prevent them, creating a smart and easy-to-living working environment.
