Temperature and relative humidity in eight spaces, illuminance next to the light-sensitive artworks, opening of six display cases and the presence of water in the stores. Battery-powered sensors with no cabling, LoRaWAN radio transmission, history and alarms from the app and from a PC.
What it does
- Eight temperature and relative humidity sensors, one per room or store, send a reading every 10 minutes to the gateway connected to the institution's network. Accuracy ±0.3 °C and ±3% relative humidity.
- For each space the conservation thresholds indicated by the conservator or required by the lender are set: when they are exceeded the notification arrives, during the day and with the museum closed.
- The history shows the daily and seasonal trend, the swings when the doors open to the public and the effect of air conditioning and dehumidifiers: this is the material for the periodic reports to conservators and restorers and for the documentation required for loans.
- The two light sensors measure the illuminance in lux at the point where the artwork is; from the continuous recording the cumulative exposure in lux hours is obtained.
- The magnetic contacts report the opening of display cases and showcases with an immediate notification and record every intervention.
- The leak detectors, placed on the floor in the stores, warn at the first presence of water and sound on the spot.
- Data, charts and notifications can be consulted from a smartphone and from a PC.

In the complete kit the installation material linked to these devices (brackets, inspection boxes, clips, cables, enclosures) follows the size chosen. For a different size write to us from the contacts section.
Available connectivity
- Customer network (Ethernet/Wi-Fi): 1 compact indoor LoRaWAN gateway

Before you order
Is an internet connection needed in the museum?
It is needed at the point where the gateway is installed: a network socket or the institution's Wi-Fi coverage. The sensors do not use Wi-Fi, they talk to the gateway by radio. If the building has no line, the version with a 4G gateway is available, which requires a data SIM (not included, any operator, traffic below 1 GB a month). It is selected when ordering.
Do the thick walls of a historic building stop the signal?
Very thick stone masonry, vaults and basement stores attenuate the radio signal: the range inside a building depends on walls and floors, and the gateway should be placed in a central position. For buildings with very thick walls, several wings or many floors, the «large building» version is available among the options, with a gateway of greater range, IP65 and which can be powered by PoE. For separate sites one gateway per site is used.
Do you have to drill walls or display cases?
No. All the sensors are battery powered and cable free. Temperature and humidity sensors and magnetic contacts can also be fixed with double-sided tape; the leak detectors are simply placed on the floor. Screws are needed only where a mechanical fixing is preferred. On historic or decorated surfaces the choice of the spot and of the type of adhesive is up to the conservator.
Does the light sensor also measure ultraviolet?
No. It measures illuminance in lux, from 0 to 100,000 with an accuracy of ±3%, one reading every 10 minutes. The cumulative exposure in lux hours is obtained from the history. For the ultraviolet component a dedicated instrument is needed.
Do the contacts on the display cases replace the intruder alarm?
No. They report and record the openings, useful for knowing when a case was opened and for how long; they are not a certified alarm system and do not replace the existing one.
I have more rooms or more display cases
The kit is configured around the institution: sensors are added for each room, store or display case, gateway and platform stay the same. Among the product options you will find the 12 and 16 space sizes; for different situations write to us from the contacts section giving the number of rooms, stores and display cases, the floors of the building and the type of masonry: we will send you the make-up and the quotation for the adapted kit.
Battery life
The temperature and humidity sensors and the light sensors have a replaceable lithium battery with a stated life of up to 10 years with one reading every 10 minutes at 25 °C; for the temperature and humidity sensors, where the radio link is difficult, the life drops to about 6 years. Magnetic contacts about 5 years, leak detectors more than 5 years with a button cell. 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 a smartphone and a PC, with charts, thresholds and notifications; no fee for basic use. Where there is a building management system or collection management software, 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 light sensors store up to 1,000 readings and retransmit them when the connection returns; for the other sensors, after a long interruption, a gap without data may remain in the history. While the line is missing, notifications are not sent; the leak detectors sound on the spot anyway.
Do they withstand the damp of basement stores? Is an electrician needed?
Temperature and humidity sensors, the body of the light sensors and the leak detectors are IP67 and work permanently in a damp environment. Magnetic contacts and gateway are for dry indoor use: IP20 and IP30. No electrician is needed: the only powered device is the gateway, with a USB-C 5 V power adapter and a socket.
What is not included
- Display cases, showcases, dehumidifiers and air conditioning systems: they are the ones of your institution
- The data SIM, in the version with a 4G gateway
