576

577

* AT Command via Bluetooth Connection (**Recommended**): [[BLE Configure Instruction>>http://wiki.dragino.com/xwiki/bin/view/Main/BLE%20Bluetooth%20Remote%20Configure/]].

578

579

* AT Command via UART Connection : See [[UART Connection>>http://wiki.dragino.com/xwiki/bin/view/Main/UART%20Access%20for%20LoRa%20ST%20v4%20base%20model/#H2.3UARTConnectionforSN50v3basemotherboard]].

582

583

== 3.2 Serial Access Password ==

584

585

586

After the Bluetooth or UART connection is successful, use the Serial Access Password to enter the AT command window.

587

588

The label on the box of the node will print the initial password: AT+PIN=**xxxxxx**, and directly use the six-digit password to access the AT instruction window.

== 3.5 Alarm for continuously water flow ==

(((

This feature is to monitor and send Alarm for continuously water flow.

)))

(((

Example case is for Toilet water monitoring, if some one push toilet button, the toilet will have water flow. If the toilet button has broken and can't returned to original state, the water flow will keep for hours or days which cause huge waste for water.

)))

(((

To monitor this faulty and send alarm, there are two settings:

)))

* (((

(% style="color:blue" %)**Stop Duration: Unit: Second**

)))

(((

Default: 15s, If SW3L-CB didn't see any water flow in 15s, SW3L-CB will consider stop of water flow event.

)))

* (((

(% style="color:blue" %)**Alarm Timer: Units: Minute; Default 0 minutes (means Alarm disable)**

)))

(((

**Example:** 10 minutes, if SW3L-CB detect a start of water flow event and didn't detect a stop event within Alarm timer, SW3L-CB will send an Alarm to indicate a water flow abnormal alarm.

)))

(((

So for example, If we set stop duration=15s and Alarm Timer=10minutes. If the toilet water flow continuously for more than 10 minutes, Sensor will send an alarm to platform.

)))

(((

(% style="color:red" %)**Note:** **After this alarm is send, sensor will consider a stop of water flow and count for another new event. So if water flow waste last for 1 hour, Sensor will keep sending alarm every 10 minutes.**

)))

(((

(% style="color:blue" %)**AT Command to configure:**

)))

* (((

AT+PTRIG=15,10 ~-~-> Set Stop duration: 15s, Alarm Timer: 10 minutes.

)))

== 6.4 Can I connect 3rd party flow sensor other than the default one? ==

979

980

If a user wants to connect SW3L-CB to a 3rd party flow sensor such as a [[DN50 flow sensor>>url:https://valvesdirect.net/product/flow-sensor-2-inch-15-400lpm/]], that is possible. A flow sensor with pulse output is needed.

981

982

**Below is the notice for the connection:**

983

984

~1. Connect the 3rd party flow meter to the pulse input and GND of SW3L-CB.

985

986

2. Make sure the pulse output voltage of 3rd party flow sensor is less than 5v.

987

988

3. It is not recommended to use SW3L-CB to power the external flow meter, unless you are sure the external flow sensor is low power ( several uA). Otherwise the battery of SW3L-CB will be running out soon.
