PinDescription

1,8,20,23,24

The weight of the system.

21,22

The place to solder the holder to CR2032 batteries. Pin 21(+) and pin 22(-).

7,8

Power supply to the module from any power source between 1.8 V and 3.6 V. Pin 7(+) and pin8(-).

10

Input to power supply through the stabilizer. Pin 10(+), Pin 22 / 23 / 24 (-).

2

Connecting the pin to ground will cause the LED to flash during Bluetooth transmission. This causes an increase in power consumption.

18,19

UART interface lines:

  • Pin 18 - TX.
  • Pin 19 - RX.

Allowable voltage range from 0 V to 5 V.

25

Output to solder the electrode to detect the presence of water. The second electrode should be soldered to any ground pin.

BBMagic Flood Modes - Wireless Flood Sensor

To set the mode of operation, please:

  1. Turn off the power supply to the module.
  2. Press the built-in button.
  3. Turn on the power while holdingdown the button.
  4. Hold the button while counting down the LED flashes: 1 flash = 1 operating mode, 2 flash = 2 operating mode and so on.
  5. Release the button with the selected operating mode.
  6. The LED will go out for about 2 seconds and then flash several times depending on the mode set.

Operation of BBMagic Flood Module - Wireless Flood Sensor

When the BBMagic Flood starts up, it sends the standby information "ALIVE"atthe time set for the operating mode configuration. The exception isdetection of water presence, then it is sent every 6 seconds until the module does not stop detecting its presence. The content of the buffer is defined in the bbmagic_lib.h file. Sample programs can be found onthe manufacturer's website.

bbmm_buf[BBMAGIC_DEVICE_TYPE] Specify the type of module that sent the data.
bbm_buf[BBM_FLOOD_ALERT_FLAGS] Flags indicate flooding detection, the BBM_FLOOD_ALERT_MASK flag set to indicate flooding alarm.
