Ammonia and hydrogen sulphide at two points, CO2, temperature and humidity in four zones, with automatic control of extractor fans, fans and misting on 8 relay outputs. Battery-powered sensors, LoRaWAN radio transmission, data and commands from the app.
What it does
- Two detectors measure ammonia and hydrogen sulphide in the housing areas, together with temperature and humidity, and send a reading every 10 minutes to the gateway connected to the company network.
- The CO2 sensor measures the concentration from 400 to 5,000 ppm: it is the most direct indicator of air exchange when the building is closed.
- Four temperature and humidity sensors, distributed along the shed, show the hot spots and provide the two values with which the THI for heat stress is calculated.
- The 8-output controller operates extractor fans, alley fans and misting when the set thresholds are exceeded, on schedule or manually from the app.
- When the gas, temperature or humidity thresholds are exceeded a notification arrives on your smartphone.
- History and charts can be viewed from a smartphone and from a PC, also useful as documentation for animal welfare.

Top quality Milesight devices with manufacturer's warranty. Batteries included in the sensors: up to 10 years for CO2, temperature and humidity with one reading every 10 minutes, about 3 years for the gas detectors; gateway and controller are mains powered.
Available sizes
The size is selected at the top, together with version and connectivity. The diagram, the photo and the table above show the «Up to 2 sheds» size; with the other sizes only the quantities of the devices listed below change, the rest of the kit is identical.
- Up to 2 sheds: 2 ammonia and hydrogen sulphide detectors, 4 temperature and humidity sensors
- 3 sheds: 3 ammonia and hydrogen sulphide detectors, 6 temperature and humidity sensors
- 4 sheds: 4 ammonia and hydrogen sulphide detectors, 8 temperature and humidity sensors
In the complete kit the installation material related to these devices (brackets, boxes, clips, cables, enclosures) follows the chosen size. For a different size, write to us from the contacts section.
Available connectivity options
- Customer network (Ethernet/Wi-Fi): 1 semi-industrial LoRaWAN gateway
- Integrated 4G: 1 semi-industrial LoRaWAN gateway with 4G
- Extended coverage, outdoor gateway on a pole: 1 outdoor LoRaWAN gateway. IP67, PoE, 4G already on board (SIM not included); for farm centres with distant buildings
In the complete kit the material for the gateway (network cable, pole, PoE injector) changes accordingly. The SIM for the 4G versions is not included.

Before ordering
Is an internet connection needed in the barn?
It is needed at the point where the gateway is installed: a network socket or the company Wi-Fi coverage, usually in the office, in the milk room or in the technical room. The sensors do not use Wi-Fi, they talk to the gateway by radio. If there is no fixed line on the farm, 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 selected when ordering.
Does one gateway cover more than one shed?
Yes. In open field the sensors reach the gateway at a few kilometres; between sheds with metal structures and sheet metal the range is reduced, but two or three buildings of the same farm centre are covered with a single gateway in a high and central position. For distant farm buildings or sites with several centres the version with an outdoor gateway on a pole is available, with extended coverage. One gateway handles hundreds of devices.
Are the ammonia detectors suitable for the barn environment?
They measure ammonia from 0 to 10 ppm and hydrogen sulphide from 0 to 5 ppm: they serve to see when the concentration rises above the usual level and to start the ventilation, not to measure high concentrations, which exceed the full scale. The housing is IP30 and the manufacturer asks to avoid dust, water and high humidity: they must be mounted in a sheltered spot, never above the bedding or within range of washing. The measuring cell has a life of about 3 years, after which the detector is replaced.
Which loads can I control?
Anything that is operated by a contact: extractor fans, alley fans, misting and shower solenoid valves, window motors. The 8 outputs are relay contacts rated 10A resistive and 5A inductive; for motors a contactor is used. Fans, motors, power contactors and existing panels are not included: the kit controls the system you already have. On farms with forced ventilation the kit works alongside the control unit and the minimum-ventilation alarms, it does not replace them.
I have more than two sheds, or I farm pigs or poultry
The kit is configured on the farm: for each additional shed a gas detector and two temperature and humidity sensors are added, gateway and platform remain the same. Among the product options you will find the 3 and 4 shed sizes. For pig houses and poultry sheds, where ammonia often exceeds 10 ppm, write to us from the contacts section stating the species, the number of buildings, the type of ventilation and the loads to be controlled: we will send you the composition and the quotation of the adapted kit.
Battery life
The CO2 sensor and the temperature and humidity sensors have a replaceable lithium battery, with a declared life of up to 10 years with one reading every 10 minutes at 25 °C. The gas detectors have four replaceable lithium batteries and last about 3 years under the same conditions. Shorter intervals reduce the life. The charge level is visible in the app.
Where is the data viewed 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. If herd management software or a farm management system is in place, the gateway can also send the data to that system (MQTT or HTTP): the configuration is included.
What happens if the internet goes down?
The sensors keep measuring; the CO2 sensor stores the readings in memory and the gateway resumes sending when the line is restored. The control rules can be loaded onto the gateway, which carries them out even without a connection to the cloud. The loads can always be operated from the manual controls of your panel.
Is an electrician necessary?
Not for the sensors: they are battery powered and are fixed with screws, cable ties or double-sided tape. The relay controller works at 230V and must be connected in the panel by an electrician, together with the contactors of the loads.
What is not included
- Extractor fans, fans, motors and misting solenoid valves: they are those of your farm
- The data SIM, in the version with a 4G gateway
- The electrical connection of the controller in the panel
- In the "devices only" version: enclosure, contactors, cables and small parts
