LoRaWAN Flood Sensor

SKU: FLOLWE01
Version: 1.0.0

Product Description

The Flood Sensor detects the presence of water on its exposed sensor pins and sends an alarm message wirelessly when triggered. In addition, the device will regularly report the ambient temperature and humidity and send an alarm when the readings exceed thresholds that can be set for both humidity and temperature.

The device itself is designed to sit on the floor, where 3 brass telescopic pins can detect water on both hard floors (tiles) and soft carpets. The unit comes with a mounting bracket. It can be screwed or taped to the wall or floor. When the main sensor is in the bracket, a super-flat sensor pad connected by wire to the bracket is used to detect water.

When an alarm is active, the unit emits a sound and a red LED flash. The device is powered by an internal CR123 battery that lasts approximately 5 years in normal operation.

The device is controlled via LoRaWAN commands and operates as a LoRaWAN Class A device. The use of the device requires LoRaWAN network coverage. Otherwise, you need to install and operate your own LoRaWAN gateway.

Pairing with the LoRaWAN Network

Please register the device with its three keys at your LoRaWAN server before you start using it. The Device EUI is printed on the device. Enter this key and your registered email address at https://aqua-scope.com/lora to obtain the missing keys. The email address is the account email from Aqua-Scope Shop purchases or the data is provided by your point of sale.

Installation and Functions

The first step is to insert the CR123 battery. Turn the top of the sensor housing counterclockwise to open the housing. Inside you will see the functional components of the unit:

1. CR123 battery holder. Be sure to insert the battery with the correct polarity. Inserting the battery the wrong way will not damage the electronics, but will drain the battery without any function.
2. Button
3. Dual Color LED
4. Buzzer Sound
5. Computing/Communication Module
6. Temperature/Humidity Sensor

After inserting the battery, the LEDs will blink red/green. This indicates an attempt to JOIN the LoRaWAN network. Success is indicated by 3 * green blinks, failure is indicated by 3 * red blinks. Pressing the button will always force a rejoin if the device is not (anymore) joined. Pressing the button will also send a heartbeat for testing purposes. The unit constantly checks for flooding and measures temperature and humidity every 15 minutes. This interval is set in configuration parameter #2 and can be changed. If either temperature or humidity changes more than 0.5°C or 5%, a sensor report is sent. The thresholds for sending can be changed in configuration parameter #6 or #7. Regardless of any value changes, the unit will send a status report every hour. This value can be changed in configuration command #4. The food alarm is indicated wirelessly plus red LED plus buzzer on the unit.

The status report includes

• Battery status or alarm status (5 byte)
• Temperature (4 bytes)
• Humidity (4 bytes)

• Place the Sole unit directly on the floor without any other accessories.
• Mount the bracket to the wall by peeling off the 3M decal or screwing it in place with the supplied screw. Insert the sensor device into the bracket and plug the sensor pad into the bracket receptacle.

LoRaWAN Payload Commands (Payload Format)

LoRaWAN commands can be daisy chained into the payload up to the defined maximum payload size of 51 bytes. This mean that for all commands sent to defined number of bytes in the payload is required to avoid misinterpretation of command and/or command values in the receiver side. All uplink and downlink commands use FPort=10.

• Uplink Command Configuration Report: 0x04 - IDX - VAL_MSB - VAL_LSB (4 Byte): This command reports a configuration parameter of the device: IDX is the number of the configuration parameter. The 16 Bit VAL is the parameter itself. Configuration parameters are always 16 Bit values. The table below describes the configuration parameters and their values.
• Uplink Command Sensor Report: 0x06 - ID - VAL_MSB - VAL_LSB (4 Byte): This command reports sensor values. The ID indicates the sensor type and defines the format of the 16-Bit VAL. The sensor types of this devices are listed below.
• Uplink Command Firmware Version Report: 0x0a - VER_MSB VER_2 VER_3 VER LSB (5 Byte): This command reports the 32-bit value of the current firmware. It is sent unsolicited as the first command during boot-up and as replying command to downlink command 'Hardware Version Get'.
• Uplink Command Alarm Report: 0x0b - STATE - TYPE - VAL_MSB - VAL_LSB (5 Byte): This command reports start and end of alarms. The STATE-Byte indicates the status of the alarm (0x01 = active, 0x00 = inactive). The TYPE Byte indicates the type of alarm and defines the content of the 16 Bit VAL. Possible alarm IDs and the values reported are listed below.
• Uplink Command Battery Report: 0x12 - VOLT - BAT_MSB - BAT_LSB (4 Byte): This command reports the status of the battery. VOLT is the measured voltage of the battery in 100 mV steps, the BAT value is the consumption of the current battery - as counted inside the system - in mAh.

• Downlink Command Configuration Set: 0x04 - IDX - VAL_MSB - VAL_LSB (4 Byte): This command allows setting configuration parameters of the device: IDX is the number of the configuration parameter. The 16 Bit VAL is the parameter itself. Configuration parameters are always 16 Bit Values. The table below describes the configuration parameters and its values.
• Downlink Command Sensor Get: 0x06 - ID (2 Byte): This command requests the report of sensor values. The ID indicates the sensor type. The sensor types of the devices are listed below.
• Downlink Command Alarm Clear: 0x0b - TYPE (2 Byte): This command clears an alarm. TYPE is the type of alarm to be cleared. Type = 0 clears all active alarms. For other types of alarms to be cleared please refer to the uplink command 0x0b.
• Downlink Command Configuration Get: 0x14 - IDX (2 Byte): This command allows reading the configuration value IDX. The device will respond with an upstream command Configuration Report

LoRaWAN Sensor Types

The following sensor types are supported by the Aqua-Scope Monitor.

• 0x01: Temperature: VAL is temperature in 1/10 Degree Celsius, (2-complement). Example: 0x06 0x01 0x00 0xCD => Temperature 0x00CD = 205 = 20.5 C., 0x06 0x01 0xFF 0xEA => Temperature 0xFFEA = -20 = -2 C
• 0x02: Humidity: VAL is relative humidity in percent. Example: 0x06 0x02 0x00 0x3C => Humidity 0x003C = 60 = 60 % RH.
• 0x03: Uptime: VAL is the number of hours after last boot (battery change)

LoRaWAN Alarm Types

The following alarmtypes are supported by the Aqua-Scope Monitor.

• 1 (0x01): Flood Sensor Tripped. VAL is 0x01 or 0x00.
• 2 (0x02): Temperature out of limits, VAL is actual temperature. For encoding of temperature please refer to section 'LoRaWAN Sensor Types'.
• 3 (0x03): Humidity out of limits, VAL is actual humidity. For encoding of humidity please refer to section 'LoRaWAN Sensor Types'.
• 12 (0x0c): Battery Low. VAL is 0x01 or 0x00.

LoRaWAN Configuration Parameters

All Configuration Parameters are 2 Byte values that can be set and read out using LoRaWAN 'Configuration Get' and 'Configuration Set' commands.

• #2: Heartbeat Interval: This parameter defines after how many measurement intervals the sensor will send a report regardless of changes temperature or humidity. The factory default is 24 which translates together with the default value of parameter #4 (900 seconds = 15 minutes) into 24 * 15 minutes = 6 hours.
• #3: Temperature Unit: Fahrenheit (0x01) versus Celsius (0x00 = default)
• #4: Measurement Interval in Seconds: Temperature and Humidity are measured regularly. This parameter defines the time interval for these measurements in sec. The default is 900 = 15 minutes. The value range is 10 – 60000. Please note that measuring a value does not automatically cause a LoRaWAN packet sent out but only if one of the sensor values deviates more then defined in parameter #6 or #7
• #6: Temperature Change Threshold: A change by this value (in 1/10 °C) will cause a LoRaWAN report. Default = 0x05 = 0.5 °C
• #7: Humidity Change Threshold: A change by this value (in %) will cause a LoRaWAN report. Default = 0x05 = 5 %
• #8: Temperature Upper Watermark: An alarm is sent out when the temperature raises over this value. The value is defined in 1/10 °C, default is 300 = 30.0 °C.
• #9: Humidity Upper Watermark: An alarm is sent out when the humidity raises over this value. The value is defined in %, default is 90 = 90 %
• #10: Temperature Lower Watermark: An alarm is sent out when the temperature drops below this value. The value is defined in 1/10 °C, default is 0xFF38 = -200 = -20.0 °C.
• #11: Humidity Lower Watermark: An alarm is sent out when the humidity drops below this value. The value is defined in %, default is 10 = 10 %
