Occupancy and number of uses of 8 cubicles, ammonia and hydrogen sulphide in the 2 washroom blocks, buttons to request cleaning or help, leaks behind the sanitary fixtures. The team steps in when it is needed, not on a timetable. Battery-powered sensors, no cameras, LoRaWAN radio transmission.
What it does
- A ceiling sensor in each cubicle detects whether it is free or occupied, with a declared accuracy above 99.5%. It is not a camera: it measures a distance and body heat, it produces no images.
- The history shows how many times each cubicle has been used: the cleaning round is decided on the number of uses, and a cubicle occupied for too long generates a notification.
- The odour detector in each block measures ammonia (0-10 ppm) and hydrogen sulphide (0-5 ppm): when the threshold is exceeded the team receives the request to attend that block.
- Each button distinguishes three presses, short, double and long, and a meaning is assigned to each one: cleaning request, paper or soap run out, call for help.
- The floor leak sensors behind the sanitary fixtures report water at 0.5 mm with a notification and a buzzer.
- The notifications reach the smartphone of the staff on duty; history and charts by block and by time of day can be consulted from a PC.

How it is installed
What is in the kit

| Qty | Device | What it is for |
|---|---|---|
| 1 | Compact indoor LoRaWAN gateway | Collects the sensor data and sends it to the cloud. Customer Ethernet or Wi-Fi, USB-C 5 V power supply. |
| 8 | Occupancy sensor for a washroom cubicle, ceiling mounted | Free or occupied status of each cubicle, without images. The number of uses is derived from this. |
| 2 | Odour detector: ammonia, hydrogen sulphide, temperature and humidity | Request to clean the block when the threshold is exceeded. |
| 8 | Three-press button | Cleaning request, report of supplies run out, call for help. |
| 4 | Floor water leak sensor, IP67 | Reports water at 0.5 mm with a notification and a buzzer. |
Milesight devices of the highest quality with manufacturer warranty. Batteries included in all the sensors; the gateway is mains powered via USB-C 5 V.
Available sizes
The size is chosen at the top, together with version and connectivity. The diagram, the photo and the table above show the «8 cubicles, 2 blocks» size; with the other sizes only the quantities of the devices listed below change, the rest of the kit is identical.
- 4 cubicles, 1 block: 4 washroom occupancy sensors, 1 ammonia and hydrogen sulphide detector, 4 call buttons, 2 water leak sensors
- 8 cubicles, 2 blocks: 8 washroom occupancy sensors, 2 ammonia and hydrogen sulphide detectors, 8 call buttons, 4 water leak sensors
- 16 cubicles, 4 blocks: 16 washroom occupancy sensors, 4 ammonia and hydrogen sulphide detectors, 16 call buttons, 8 water leak sensors
- 24 cubicles, 6 blocks: 24 washroom occupancy sensors, 6 ammonia and hydrogen sulphide detectors, 24 call buttons, 12 water leak sensors
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 contact section.
Available connectivity
- Customer network (Ethernet/Wi-Fi): 1 compact indoor LoRaWAN gateway

Before you order
Is an internet connection needed in the washrooms?
Not in the washrooms. It is needed at the point where the gateway is installed: a network socket or the building Wi-Fi coverage. The sensors do not use Wi-Fi, they talk to the gateway by radio. If you cannot use the building network, the version with a 4G gateway is available, which requires a data SIM (not included, any operator, less than 1 GB of traffic per month). You choose it when ordering.
Does one gateway cover several washroom blocks?
Inside a building the range depends on walls and floor slabs: the gateway goes in a central position with respect to the blocks. For two blocks on the same floor or on nearby floors the compact gateway is adequate. For long shopping malls, stations, several floors or blocks far apart, choose the «large building» variant: semi-industrial IP65 gateway, with more range and able to be powered over PoE. One gateway handles hundreds of sensors.
Are there cameras? And what about user privacy?
No cameras and no microphones. The cubicle sensor combines a distance meter and a passive infrared sensor: it only transmits the free or occupied value, it identifies nobody.
How does the request reach the cleaning team?
As a notification in the app of the staff on duty, with the name of the block or of the cubicle and the reason: odour threshold exceeded, number of uses reached, button pressed, leak. Anyone already using work order software can receive the same events in that system and turn them into tickets.
I have more than 8 cubicles, urinals or washrooms on several floors
Among the product options you will find the 16 and 24 cubicle sizes, with odour detectors, buttons and leak sensors in proportion; gateway and platform stay the same. For different compositions write to us from the contact section stating the number of blocks, cubicles per block and floors: we will send you the composition and the quotation for the adapted kit.
How often are batteries and sensors replaced?
Cubicle sensors: about 4 years with 90 uses a day. Odour detectors: about 3 years with one reading every 10 minutes; the gas measuring cells also last 3 years, after which the detector has to be replaced. Buttons: over 7 years. Leak sensors: about 5.7 years. The batteries are lithium and replaceable; the charge level is visible in the app.
Where is the data consulted and are there any fees?
In the manufacturer's app and portal, from smartphone and PC, with charts, thresholds and notifications; no fee for basic use. Where facility management software, a ticketing system or monitors showing the free cubicles are present, 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 detecting and transmitting to the gateway; the notifications resume once the line is back. The leak sensors sound on the spot anyway with the built-in buzzer. For a call for help the button does not replace a call system compliant with the standards for accessible washrooms.
Is an electrician needed?
No. All the sensors are battery powered and are fixed with screws or double-sided tape. The gateway is powered from a 5 V USB-C outlet and connects to the network with an Ethernet cable or over Wi-Fi.
Do they withstand humidity and wash-downs?
The leak sensors are IP67. Cubicle sensors, odour detectors and buttons are IP30: they work with humidity up to 95% without condensation, but they must not be reached by jets of water. On the ceiling and 2 m above the floor they are out of reach of ordinary wash-downs; the buttons go in a position sheltered from splashes.
What is not included
- Sanitary fixtures, doors, dispensers and signage: those are the ones in your washrooms
- The data SIM, in the version with a 4G gateway
- The 5 V USB power supply for the gateway, if you do not already have one
- Monitors or panels to show the free cubicles
- In the "devices only" version: network cable, spare batteries, wall plugs, double-sided tape and labels
