1. Introduction
MiDoMet water leak sensor R311W is a LoRaWAN device compatible with LoRaWAN protocol (ClassA). When the R311W sensor detects a leak, it
will send an alarm message to the gateway. When the sensor detects no leaks, it will send a message that shows no leak to the gateway.
LoRa Wireless Technology:
LoRa is a wireless communication technology dedicated to long distance and low power consumption. Compared with other communication methods,
LoRa spread spectrum modulation method greatly increases to expand the communication distance. Widely used in long-distance, low-data wireless
communications. For example, automatic meter reading, building automation equipment, wireless security systems, industrial monitoring. Main features
include small size, low power consumption, transmission distance, anti-interference ability and so on.
LoRaWAN:
LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and gateways from different
manufacturers.

4.Set up Instruction
On/Off
Power on
Insert batteries.
(users may need a flat blade screwdriver to open); insert two sections of 3V CR2450
button batteries and close the battery cover.)
Turn on
Press any function key till green and red indicator flashes once.
Turn off
(Restore to factory
setting)
Press and hold both function keys for 5 seconds till green indicator flashes for 20 times.
Power off
Remove Batteries.
Note:
1. Remove and insert the battery; the device memorizes previous on/off state by default.
2. On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor inductance and other
energy storage components.
3. Press any function key and insert batteries at the same time; it will enter engineer testing mode.
Network Joining
Never joined the network
Turn on the device to search the network.
The green indicator stays on for 5 seconds: success
The green indicator remains off: fail
Had joined the network
Turn on the device to search the previous network.
The green indicator stays on for 5 seconds: success
The green indicator remains off: fail
Fail to join the network
(when the device is on)
First two mins:wake up every 15 seconds to send request.
After two mins: enter sleeping mode and wake up every 15 minutes to send request.
Note: Suggest to remove batteries if the device is not used to save power.
Suggest to check the device verification information on the gateway with your platform server provider.
Function Key
Press and hold for 5
seconds
Restore to factory setting / Turn off
The green indicator flashes for 20 times: success
The green indicator remains off: fail
Press once The device is in the network: green indicator flashes once and sends a report
The device is not in the network: green indicator remains off
Sleeping Mode
The device is on and in
the network
Sleeping period: Min Interval.
When the reportchange exceeds setting value or the state changes: send a data report according to Min Interval.
The device is on but not in
the network
First two mins: wake up every 15 seconds to send request.
After two mins: enter sleeping mode and wake up every 15 minutes to send request.
Note: Suggest to remove batteries if the device is not used.
Suggest to check device verification on gateway.
