PM2.5 and PM10 dust, TVOC index, CO2, temperature and humidity in three departments, sound level at four workstations, climate in the storage areas and illuminance at the quality control benches. Continuous recording, LoRaWAN radio transmission, exportable history.
What it does
- In each department an air quality monitor measures PM2.5 and PM10 dust from 0 to 1,000 µg/m³, the TVOC index on a scale from 1 to 5, CO2 from 400 to 5,000 ppm, temperature, humidity and pressure, with one reading every 10 minutes.
- The sound level sensors record at the workstations the value in dB(A), the equivalent level Leq and the maximum Lmax of each interval: you can see in which hours and with which operations the noise rises.
- The temperature and humidity sensors follow the storage areas for wood, paints, semi-finished goods and packaging.
- The illuminance sensors measure the lux on the surface of the quality control benches and show the decline of the lamps over time.
- When the set thresholds are exceeded the notification is sent to your smartphone; the air monitors also have a traffic-light indicator and a buzzer in the department.
- The history of every quantity remains available with charts and export: it documents the trend over time and the effect of extraction, air changes and interventions, in support of audits and safety meetings.

Milesight devices of the highest quality with the manufacturer's warranty. Batteries included in all the sensors; the air quality monitors can also be powered at 5 V via USB-C, the recommended choice for a fixed installation; the gateway is mains-powered.
Available sizes
The size is chosen at the top, together with version and connectivity. The diagram, the photo and the table above show the «3 departments» size; with the other sizes only the quantities of the devices listed below change, the rest of the kit is identical.

- 6 departments: 6 dust and air quality sensors, 8 noise sensors, 8 temperature and humidity sensors, 4 light sensors
In the complete kit the installation material linked to these devices (brackets, boxes, clips, cables, enclosures) follows the size chosen. For a different size write to us from the contacts section.
Available connectivity options

Before you order
Is an internet connection needed in the department?
It is needed at the point where the gateway is installed: a socket of the company network or the Wi-Fi coverage. The sensors do not use Wi-Fi, they talk by radio with the gateway. If there is no network in the plant, or if you do not want to connect the system to the company network, the version with a 4G gateway is available, which requires a data SIM (not included, any operator, traffic below 1 GB per month). It is chosen when ordering.
Are the measurements valid for the risk assessment?
No, they complement it. Noise, dust and chemical agents are assessed with the instruments and methods prescribed by the regulations: certified sound level meters, personal sampling, laboratory analysis. These sensors have an accuracy of ±3 dB on noise and ±10 µg/m³ on dust up to 100 µg/m³, and for volatile organic compounds they give an index from 1 to 5, not a concentration. They provide what a one-off measurement does not give: the continuous trend, the critical hours and operations, the verification that extraction and air changes are working, the history to show in audits.
Can they be fitted in a paint booth or near the dust silos?
No. The devices are not ATEX certified and must not be installed in areas classified as explosion risk: paint booths, mixing rooms, silos and wood dust filters. They are installed in the department, outside the classified areas.
Do they cope with the dust and the humidity of the department?
The temperature and humidity sensors are IP67; in the illuminance sensors the transmitter body is IP67 and the measuring element IP65. Air monitors, noise sensors and gateway are IP30, for indoor use, operating from -20 to +60 °C: they go in a position sheltered from jets, chips and direct dust; the gateway goes in a panel. In very dusty departments the dust sensor requires a position away from the source.
Does one gateway cover the whole plant?
For this gateway the manufacturer declares up to 2 km in urban areas and 15 km in open field; inside a plant, walls, metal structures and machines count. With the gateway in a central position and the antenna outside the panel, high up, a building with several departments is normally covered. For several buildings or distant blocks a second gateway is added. One gateway manages hundreds of devices.
I have more than 3 departments or more noisy workstations
Among the product options you will find the 6-department size, with twice as many sensors. The kit is in any case configured on the plant: air monitors, noise sensors or illuminance sensors are added where they are needed, the gateway and the platform stay the same. Write to us from the contacts section with the departments, the operations and the number of workstations: we will send you the composition and the quotation for the adapted kit.
Battery life
Illuminance sensors and temperature and humidity sensors: declared life up to 10 years with one reading every 10 minutes. Sound level sensors: about 5 years, about 1.7 years if continuous measurement with fast weighting is enabled. Air quality monitors: about a year and a half on batteries, because the dust sensor consumes power; for this reason it is best to power them at 5 V via USB-C, with an ordinary USB power supply. The batteries are lithium, replaceable, and the charge level is visible in the app.
Where is the data consulted and are there subscription fees?
On the manufacturer's app and portal, from smartphone and PC, with charts, thresholds and notifications; no fee for basic use. The history is exported for reports and audits. Where there is a supervision system or a business management system, the gateway can also send the data to that system (MQTT or HTTP): the configuration is included.
What happens if the internet is down?
The sensors keep measuring. The air quality monitors and the illuminance sensors keep the readings in their internal memory and retransmit them when the line is restored; the traffic-light indicator and the buzzer of the monitors work in the department in any case. The notifications on your smartphone are not sent until the line comes back.
Is an electrician needed?
Not for the sensors: they are battery-powered and are fixed with screws, double-sided tape or cable ties. The gateway must be mounted on a DIN rail in a panel and powered via PoE or USB-C: that is a job for an electrical maintenance technician. The same applies if you decide to bring a socket near the air monitors to power them from the mains.
What is not included
- The USB power supplies for the air quality monitors, if you choose to power them from the mains
- The data SIM, in the version with a 4G gateway
- The panel in which to mount the gateway and its PoE injector, if needed
- Instrumental measurements and technical reports for the purposes of the risk assessment
- In the "devices only" version: DIN rail, external antenna, network cable, cable ties and small fixings
