Background
Covid-19 broke out in Hong Kong in early 2020, and the community expects that the epidemic will be alleviated by vaccination. At that time, various business activities will be restarted, and students will start to return to school. Reducing the risk of mutual infection will be the task of many companies in Hong Kong in the coming year. Adding disinfection and testing equipment in the ventilation ducts is a way to enhance the environmental hygiene of the classrooms and shopping malls and reduce mutual infection.
Solution
We have a set of IoT monitoring solutions for indoor environment management. By installing corresponding wireless sensors, We can manage indoor air quality online.
- Disinfect the air
- Reduce the chance of mutual infection
- Manage indoor environment easily
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.
The warehouse environment optimization management system has a strong back-end data for the future development
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
- Installation of Indoor Sensing Device – Manage Automatically
HVAC Air Sterilizer
When the air passes through the ultraviolet light lamp, the ultraviolet light destroys bacteria, viruses, allergens and moulds, and disinfects the air.
Ultraviolet rays are different from chemical disinfectants. Ultraviolet rays can quickly and effectively inactivate microorganisms through physical processes. When bacteria and viruses are exposed to the germicidal wavelength of ultraviolet light, they cannot multiply and infect.
TVOC Air Quality Sensing Device
The TVOC air quality sensing device can monitor the air quality in real-time and flexibly transmit data, automatically activate the ventilation system, inhale the fresh air, and exhaust the impurity air in the room to improve the indoor air quality.
Laser PM2.5 Air Quality Sensor (For excavators)
The sensing device can calculate the amount of indoor dust with laser technology and flexibly transmit data, automatically start the ventilation system, inhale the fresh air, and exhaust the impurity air in the room to improve the indoor air quality.
Conclusion
A safe environment and good air quality are very important to public health. It is one of the tasks of many companies in Hong Kong to find a sterile working and trade space that can ensure that workers and customers have a clean environment. Managers can record the indoor air quality through the management system 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 manager to initiate the preset response in time Measures to maintain normal indoor air quality. A good indoor environment could be ensured.
