Introduction

The Severn Board, combined with Severn Sensors, forms LAIIER’s Severn WLD solution: a water leak detecting sensor. This solution is able to detect small amounts of liquid, wirelessly transmitting this data to the LAIIER Cloud™ via LoRaWAN. The Severn Board is powered with a single AA battery. Once the battery is inserted, the unit is controlled using a magnet that triggers a magnet sensor and the board’s status is indicated using an on-board RGB LED. At power-on, the device connects to a LoRaWAN network via OTAA authentication and then is stepped through signal strength indication and self-test using a magnet swipe gesture to advance each stage. Once self-test is passed the unit enters a low-power state, waking once every minute to measure a number of resistances on the Severn Sensor. LoRaWAN messages are sent to determine signal strength and to communicate the self-test result to the gateway. If the resistances on the printed sensor breach particular thresholds, a LoRaWAN message is sent. If a given period has elapsed with no LoRaWAN messages having been sent, a message is sent to indicate that the unit is still operating. Swiping the magnet across the unit when it is running puts it back into self- test mode. After the self-test ran, another LoRaWAN message is sent, allowing the end user to check that the unit is operating correctly if required.

Installation

1. First, open the board by unlatching the two levers on the side.
2. On the side of the board, you will find an FFC connector. Lift up the latch of the connector up and slide in a Severn Sensor, with the contacts facing upwards, inside the FFC connector. Once inside, close the FFC connector again by pushing down the latch. Give a small tug to the sensor, it should be securely attached and not come loose. If it does, open the FFC connector and try to move the sensor further in.
3. To power, the board, remove the battery safety pull tab between the Li-SOCl₂ cell battery and the battery holder inside the board. The board’s LED should light up in blue.
4. Place the top of the enclosure back and close the board again.
5. You can now attach the Severn Board and Severn Sensor to the surface that you want to monitor for leaks. Simply peel away the protective layer of the 3M adhesive from the sensor and the board and stick them down. Make sure to clean the surface you want to attach the sensor to from any debris and dirt, as the sensor won’t adhere well otherwise; we recommend cleaning the surface with an IPA.

Board Behaviour at Start-Up and Self-Test

1. Upon powering the board, the board’s LED will flash blue for one second.
2. It will then attempt to connect to the LoRaWAN network, with the LED now flashing blue continuously.
3. Once the board has successfully joined the LoRaWAN network, the LED will flash red, yellow or green, depending on the strength of the network.
4. To activate the board into running self-tests, you now have to swipe with a magnet on the side of the board. Alternatively, you can also wait 10 minutes, at which point the board will enter the self-test mode automatically.
5. During the self-test, the LED turns white. Once it has run the self-test, the LED will display one of the following results, with the result also being sent as a message to the LoRaWAN network:

• Water is present on the sensor
• Board has passed the self-test
• The sensor isn’t connected correctly
• Internal error

1. If the LED flashes yellow, check that the Severn Sensor is correctly attached to the board. You don’t need to remove the battery, you can simply open the FCC connector switch and take the sensor out and push it in again. If the LED flashes red, please contact us at info@laiier.io.
2. To then set the board into run mode you either swipe the magnet again on the side of the board, or wait 10 minutes. The LED flashes green for a second and then the board is set to run mode.
3. When the board is set into run mode, it will check the status of the sensor every minute. Each sensor is split into 12 electrodes and if no water is present, then the board sends a message every hour to state that everything is okay.
4. If the board detects that three adjacent sensor electrodes report a change past a pre-defined threshold within a one minute period, then it classifies this as a leak occurring.
5. This message is sent every 10 minutes until the leak has been fixed and the board reset.
