Structural monitoring kit, from 6 to 36 points
Twelve battery-powered three-axis tilt sensors record over time the rotation of the points chosen by the engineer; two temperature and humidity sensors make it possible to separate the thermal effect from real drift. LoRaWAN radio transmission, history and thresholds from the app and from a PC.

Customisable kits. This is one of the Milesight LoRaWAN kits in the Smart Home Kit section. For different installations, custom kits or bespoke automation, write to us from the contact section.
Several sizes. The figures, diagram and table on this page describe the «12 points» size. The other sizes are chosen at the top and are listed further down, under «Available sizes».
12 measuring pointsTilt on the three axes with respect to the installed position, range ±90°, resolution 0.01°.
Reference temperature2 temperature and humidity sensors to read the daily and seasonal variations alongside the tilt readings.
Trend and thresholdsOne reading every 10 minutes or at the chosen interval, long-term charts, alarm on a threshold in degrees.
No cables on the structureSelf-contained sensors fixed with two anchors: no lines, no control units, no permanent scaffolding.
What it does
- Each sensor, fixed flush against the structure, measures the tilt on the three axes and reports it as the deviation from the position stored at the end of installation.
- The readings arrive at regular intervals, from 1 minute to 18 hours; the factory setting is 10 minutes. The history shows the trend over days, weeks and seasons.
- Two temperature and humidity sensors, one on the exposed side and one on the shaded side, give the thermal reference: the daily and seasonal swing, which comes and goes, can be told apart from a drift that accumulates.
- Thresholds in degrees are set for each point: when one is exceeded, a notification goes to the engineer in charge, to the building manager or to the operator of the structure.
- The outdoor gateway collects the data of the twelve points and sends it to the cloud through the network available on site or, alternatively, with a 4G SIM.
- The data can be consulted from a smartphone and from a PC and can be sent automatically to the system of the engineer or of the operator for their own processing.
For a different number of points, several structures in the same area, sites without mains power that require the solar gateway, additional temperature sensors, sending the data to a system of your own: tell us the characteristics of the structure from the contact section and we will propose the correct configuration with a quotation.
1Outdoor IP67 LoRaWAN gateway on a pole or on a wall, on a nearby building with power and network: it collects the data of all the points and sends it to the cloud.
2Three-axis IP67 tilt sensor, fixed flush against the structure at the points chosen by the engineer. Twelve in the kit.
3IP67 temperature and humidity sensor: one on the side exposed to the sun, one on the shaded side. Two in the kit.
How it is installed
Gateway. At the top of a pole between 67 and 127 mm in diameter or in the upper part of a wall, with the two 60 cm antennas vertical, clear beyond the edge of the wall and at least 35 cm from walls and obstacles. It does not have to be mounted on the structure being monitored: a nearby building with power and network, in view of the structure, is fine. PoE power from a single network cable, with the injector supplied, to be kept indoors. Connectors to be taped with insulating tape and waterproof tape; earth terminal to be connected. IP67, operation from -40 to +70 °C.
Choice of the points. The measuring points are established by the engineer in charge on the basis of the pattern of damage: typically the top and the foot of a retaining wall, the two sides of a through crack, different heights of a bell tower or of a pier, the abutments of a bridge. Each sensor receives a numbered label that corresponds to the point on the installation diagram.
Fixing of the tilt sensors. With anchors and screws on a sound support, masonry, concrete or steelwork, not on detached plaster; on tubes and profiles with a plate and clamps. The sensor must sit flush against the surface with no play at all and one of its three axes must be parallel to the axis of rotation of interest, otherwise the reading is not correct. The vent slot must not face upwards. Away from extensive metal masses that shield the radio signal. IP67, operation from -30 to +60 °C.
Temperature and humidity sensors. On a wall with two screws in a horizontal line, or with a clamp on a pipe or a downpipe: one on the elevation exposed to the sun, the other on the shaded side or indoors, close to the measured points. IP67, measuring range from -30 to +70 °C.
Configuration. Via NFC with a smartphone and the manufacturer's free app, with the sensor already fixed: reading interval, storing of the initial position, thresholds in degrees. The gateway is configured from a browser. No cables and no paid software are needed.
Documentation included. A written installation guide with the criteria for fixing and for orienting the axes, the switch-on and zeroing sequence, and the initial configuration of the intervals, point names and thresholds indicated by the engineer when ordering.

Before you order
Do you need mains power and internet on site?
For the gateway, yes: a socket for the PoE injector and a network connection, which can be in a nearby building. Alternatively the same gateway works with a data SIM (not included, any operator, traffic below 1 GB per month) and only needs the socket. For isolated structures without power, such as bridges, walls along a road or slopes, the version with a solar 4G gateway is available. You choose when ordering. The sensors are battery powered and need nothing.
How far from the structure can the gateway be?
The manufacturer states up to 2 km in an urban area and 15 km in open ground. In practice it is best to keep the gateway high up and in view of the structure. Sensors placed inside thick masonry, in basement rooms or inside metal boxes receive less well: reception is checked from the app before the final fixing. One gateway handles about 2,000 devices.
How accurate are the tilt sensors?
Range ±90° on the three axes, accuracy ±1°, resolution 0.01°. They are suited to continuous surveillance and to reading trends: they show whether a point is rotating, in which direction and at what speed, and give a warning when a threshold is exceeded. They are not precision inclinometers for acceptance testing: where measurements certified to the hundredth of a degree are needed, the kit works alongside specialist instrumentation and manual readings, covering the intervals between one campaign and the next.
How is temperature taken into account?
The sensors do not apply an automatic thermal compensation. The two temperature and humidity sensors record the trend on the exposed side and on the shaded side: by overlaying the charts you recognise the component that follows the daily and seasonal cycle. Reading the data and defining the thresholds remain with the engineer in charge.
I have more than 12 points or more structures
Among the product options you will find the 24-point and 36-point sizes, with the same gateway. For different numbers or for several structures far apart, write to us from the contact section stating the type of structure, the number of points and the availability of power: we will send you the composition and the quotation for the adapted kit.
Battery life
The tilt sensors have two replaceable lithium batteries: about 4 years with one reading every 10 minutes at 25 °C, about 3 with a weak radio link; longer intervals extend the life. The temperature and humidity sensors range from about 6 to more than 10 years. The charge level is visible in the app, so the replacement can be scheduled together with a site visit.
Where is the data consulted and are there any fees?
On the manufacturer's app and portal, from a smartphone and a PC, with charts, thresholds and notifications; no fee for basic use. Where there is a monitoring platform of the engineering firm or of the infrastructure operator, the gateway can send the data to that system as well (MQTT or HTTP): the configuration is included.
What happens if the network is down?
The sensors carry on measuring and transmitting to the gateway; the upload to the portal and the notifications resume when the line returns. Where continuity of the history is essential, the version with a 4G SIM is preferable, because it does not depend on the network of the building, or the solar version, which does not even depend on mains power.
Is an electrician needed?
No. The sensors are battery powered and are fixed with two anchors. The gateway receives power and data from a single extra-low voltage network cable; the injector is plugged into an existing socket. A mobile scaffold tower or a platform is needed for the points at height and, on public structures, the authorisations of the operator.
Protection rating
The gateway and the sensors are IP67, for permanent outdoor installation. Operation from -30 to +60 °C for the tilt sensors, from -30 to +70 °C for the temperature and humidity ones, from -40 to +70 °C for the gateway, which has a die-cast aluminium body.
