DW10-868
Model Name: DW10
BQW_02_0034.005
Description
The MerryIoT Open/Close sensor utilizes LoRaWAN connectivity to communicate
the proximity or not of a magnet. The intended use is to place the sensor and
magnet on separate elements of a door or window to determine if the door or
window is open or closed. The sensor is composed of two parts. The main body
contains active electronics to measure magnetic fields and transmit any
changes to a LoRaWAN network. The second part is a permanent magnet of
sufficient field strength to be detected by the Hall Effect sensor on the main
body.
There are also vibration and tilt detection in case of tampering.
Once the event is detected, the sensor will send an uplink and keep a buzzer
alarm (Optional).

Operation
Installation Mode
- Users need to press the button over 5 seconds to activate operation into installation mode. When the Sensor tries to join the network, it will keep blinking for 3 seconds.
- Once the sensor joins the network, the LED will keep on for 3 seconds and send an uplink
- Users can press the button for over 5 seconds to try to join the network again.
- The device will send uplink three times with FW version when the device joined successfully.
Default Operation
- While in default operation the device will immediately send a message any time there is a transition and buzzer alarm (Optional) in the below event
- Open to Close (No buzzer alarm)
- Close to Open (Buzzer alarm)
- Tamper detected (Vibration or tilt detected) (Buzzer alarm)
- Button pressed (No buzzer alarm)
- Keepalive message (No buzzer alarm)
- Users can press the button to send a test message to the network
- The device will send a message saying it has been inactive for 6 hours.
- While in default mode the device will flash the LED 3 times within 100ms only when the user presses the test button
