Since the outbreak of the coronavirus pandemic, good ventilation is an important factor in preventing the virus. The biggest contributor to carbon dioxide in an indoor space is people exhaling. Higher levels of CO2 in a building are an indicator of poor ventilation which increases the risk of the virus spreading and causes a variety of health issues. Hence real-time monitoring of CO2 level helps decide if ventilation is poor and keep good air quality. To fight with COVID-19, Milesight offers a LoRaWAN® indoor air quality monitoring solution.

COVID-19 Solution

The COVID-19 solution consists of hardware and software, including end nodes, gateway and cloud platform. Place a UG65 LoRaWAN® Gateway at the top of the building to set up a LoRaWAN® network, covering the whole school; place an AM107 ambiance monitoring sensor in each classroom to detect CO2 level; connect UC1114  LoRaWAN® controller with control the panel of ventilator fans to uses relay out to turn on/of them. Milesight IoT Cloud offers remote monitoring, alert and auto control.

Device List

• UG65 LoRaWAN® gateway
• AM107 Ambiance Monitoring Sensor
• UC1114  LoRaWAN® Controller

COVID-19 Solution Scenario: Clean Air Auto Control

CO2 concentrations above 1000 ppm are likely to cause feelings of discomfort, such as fatigue, loss of concentration or headaches. Concentrations above 750 ppm are likely to cause stiffness and odors. For the sake of students and teachers, once AM107 detects that the concentrations are above 700 ppm, Milesight IoT Cloud will automatically turn on the ventilation fan and turn off the fan after concentrations fall back to 500 ppm, keeping air quality in proper condition and saving energy.

Solution Scenario: Extra Applications 

AM107 ambiance monitoring sensor consists of multiple smart sensors that detect temperature, humidity, motion (PIR), light, CO2, TVOC and barometric pressure. Combined with the smart trigger system of Milesight IoT Cloud, UC1114  can smartly use relay out to turn on/of equipment like light bulbs, ventilators and air conditioners. In conclusion, the solution can also be used for smart air comfort control, smart lighting, room occupancy monitoring, and so on.
