Customisable kits. This is one of the Milesight LoRaWAN kits in the Smart Home section. For different installations, custom kits or bespoke automations, write to us from the contact section.
Several sizes. The figures, diagram and table on this page describe the «12 classrooms» size. The other sizes are selected at the top and are listed further down, under «Available sizes».
12 classroomsOne sensor per classroom, wall-mounted with screws or double-sided tape, with no building work.
CO2 from 400 to 5,000 ppmInfrared measurement, together with temperature and humidity, with one reading every 10 minutes.
Display in the classroomThe teacher reads the value on the screen and decides when to open the windows.
History and notificationsCharts by classroom and by time slot, alerts when 1,000 and 1,500 ppm are exceeded.
What it does
- In every classroom a wall-mounted sensor measures CO2, temperature and humidity and sends a reading every 10 minutes to the two gateways connected to the school network.
- The e-ink display shows the values in the classroom, always visible without an app and without switching anything on: whoever is at the teacher's desk sees when it is time to air the room.
- The thresholds are preset at 1,000 ppm (air the room) and 1,500 ppm (air the room immediately) and can be changed at any time.
- When the thresholds are exceeded the system sends a notification to the people you specify: the site coordinator, the school caretakers, the health and safety officer.
- The classroom-by-classroom history shows in which rooms and at which times the air exchange is not enough: it serves to organise the window openings, to assess a ventilation system and to document the measures taken.
- Temperature and humidity flag the classrooms that are cold, overheated or too dry during the heating season.
- All the data can be consulted from a smartphone and from a PC with charts and notifications.
For a different number of classrooms, several school sites, a gym, canteen and laboratories to be added, buildings with thick walls or several blocks that require a different gateway, premises without a data line: tell us the characteristics of your school from the contact section and we will propose the correct configuration together with the quotation.
1Compact indoor LoRaWAN gateway, connected to the school network: it collects the classroom data and takes it to the cloud. Two in the kit, one per floor or per wing.
2CO2, temperature and humidity sensor with display, on the wall at least 1.5 m above the floor. One per classroom, twelve in the kit.
How it is installed
Gateway. Two compact indoor gateways, to be placed on a piece of furniture or fixed to the wall or the ceiling with the supplied plate: one in a central position with respect to the classrooms, the second on the furthest floor or wing. A corridor, the school office or a technical room are all fine, provided there is a network socket or the school Wi-Fi and a power socket. USB-C 5 V power supply, connection with Ethernet cable or Wi-Fi. IP30 protection, operation from -20 to +50 °C: in dry rooms only.
Position of the sensors in the classroom. On the wall, at least 1.5 m above the floor, on an internal wall. Away from windows, doors, radiators, ventilation grilles and air conditioners, which distort the reading. They must not be mounted upside down. A position near the teacher's desk makes the display readable by the teacher.
Fixing. With the double-sided tape on a smooth, clean surface or with two wall plugs and screws. The anti-theft screw on the underside locks the sensor to the plate: in classrooms it is recommended. Each sensor receives a numbered label that corresponds to the classroom in the installation diagram.
Switch-on and calibration. The sensors are switched on and paired with the gateway from the smartphone. The CO2 measurement is calibrated in two ways: automatically, on the background value that the classroom reaches when it is empty and aired, or by hand, leaving the sensor in the open air for more than 10 minutes. In classrooms that are aired every day the automatic calibration is enough.
Configuration. Via NFC with a smartphone and the manufacturer's free app: reading interval, CO2 thresholds, classroom name. The gateways are configured from a browser. No cables or paid software are needed.
Documentation included. Written installation guide with heights, positions to avoid, switch-on and calibration sequence, and the initial configuration of thresholds and classroom names based on the list provided when ordering.

Before you order
Is the school network needed?
It is needed only for the two gateways: an Ethernet socket or the school Wi-Fi, with outbound internet access allowed by the firewall. The traffic generated is minimal. The sensors in the classrooms do not use Wi-Fi and do not join the teaching network: they talk to the gateways by radio. For a site without a data line a 4G gateway can be provided, which requires a data SIM (not included): write to us from the contact section.
Are two gateways enough for the whole building?
Inside a building the range depends on walls and floor slabs, which is why there are two gateways: one in a central position and one on the furthest floor or wing. For a school on two or three floors this is the usual arrangement. With very thick load-bearing walls, several blocks or many floors the «large building» variant is preferable, in which the main gateway is a semi-industrial model with greater range, IP65 protection and PoE power from the network cable. Each gateway handles about 2,000 devices: adding classrooms does not require replacing them.
We have more than 12 classrooms or several school sites
Among the product options you will find the 24 and 48 classroom sizes. For different numbers, for several school sites or to add a gym, canteen and laboratories, write to us from the contact section stating the number of classrooms, floors and sites: we will send you the composition and the quotation for the adapted kit.
Can the students detach it or tamper with it?
The sensor is fixed to the wall with wall plugs and an anti-theft screw that locks it to the plate: a tool is needed to remove it. The settings are protected by a password. It has no microphone and no camera: it measures only CO2, temperature and humidity.
Does the CO2 sensor need calibrating?
The automatic calibration corrects the measurement on the background value that the classroom reaches when it is left empty and aired, and it is suitable for rooms that are ventilated regularly. Alternatively the manual calibration is carried out: the sensor in the open air for more than 10 minutes and a command from the app. The stated accuracy is ±(30 ppm + 3% of the reading).
Battery life
Each sensor uses two replaceable lithium batteries. With one reading every 10 minutes at 25 °C the stated life goes from about 3 to about 4.5 years, depending on the quality of the radio link. The charge level is visible in the app.
Where is the data consulted and are there any fees?
On the manufacturer's app and portal, from smartphone and PC, with charts, thresholds and notifications; no fee for basic use. Where there is a building management system or a platform belonging to the owning authority, the gateway can also send the data to that system (MQTT or HTTP): the configuration is included.
What happens if the school network goes down?
The sensors keep measuring and the display in the classroom stays up to date: the indication for the teacher does not depend on the internet. Notifications and the history on the portal resume when the line comes back.
Is an electrician necessary?
No. The sensors are battery powered and are fixed with double-sided tape or two screws. The gateways are powered at 5 V from a USB-C socket and connect to the network with an Ethernet cable or over Wi-Fi: it is a job within the reach of the school's IT technician.
Can they also be installed in the gym, the canteen or the laboratories?
Yes, in any dry indoor room. The sensors are IP30, with operation from -20 to +60 °C; the display works between 0 and 40 °C. They are not suitable for changing rooms with showers, kitchens with steam or outdoor use. For laboratories, the gym and the canteen there is a dedicated kit in the Smart Home section.
