1. Introduction
RB11E is a long distance wireless infrared device based on the LoRaWAN protocol (Class A).
RB11E combines infrared detection, temperature, and illumination sensors. During infrared real-time
detection, if a people or other organism which is active in the monitoring area, RB11E will detect the
infrared signal and report status information to the gateway. Users can execute different instructions
or scenes according to the different status configuration. RB11E also supports temperature, lighting
report.
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
4.1 Power on and Turn on / off
(1) Power on = Insert batteries: open the battery cover (press down case open button, open the cover
along the gap between upper and lower covers); insert two sections of ER14505 3.6V AA batteries
and close the cover.
(2) If the device had never joined in any network or at factory setting mode, after powering on, the
device is at off mode by default setting. Press function key 1 for about 1 second and release to turn
on the device. Both green and red indicator will flash once to show that RB11E is turned on.
(3) Press and hold function key for 5 seconds till the green indicator flashes quickly and release.
The green indicator will flash 20 times to show that RB11E is turned off.
Note: the interval between shutting down twice or power off/on is suggested to be about 10 seconds
to avoid the interference of capacitor inductance and other energy storage components.
4.2 Join Into Lora Network
To join RB11E into LoRa network to communicate with LoRa gateway (OTAA network mode by
default).
The network operation is as following:
(1) If RB11E had never joined any network or at factory setting mode, turn on the device; it will
search an available LoRa network to join. The green indicator will stay on for 5 seconds to show it
joins into the network, otherwise, the green indicator will be off.
(2) If RB11E had been joined into a LoRa network, remove and insert the batteries; the green
indicator will stay on for 5 seconds to show it joins into the network.
4.3 Function Key
(1) Press and hold function key for 5 seconds to reset to factory setting. After restoring to
factory setting successfully, the green indicator will flashes quickly 20 times.
(2) Press function key to turn on the device and it will send a data report.
4.4 Data Report
When the device is powered up, it will immediately send a version package and a data report
package of temperature, illumination, infrared status and voltage. The transmission frequency of
version package sending is once every 24 hours.
Data will be reported once per hour by default setting.
Maximum time: 3600s
Minimum time: 180s
Default reportchange:

Battery ---- 0x01 (0.1V)
Temperature - 0x0064 (1 ℃)
Illumination - 0x0032（50Lux)
Note: MinInterval is the sampling period (voltage, temperature, illuminance).
Sampling period >= MinInterval.
When infrared is triggered: The red LED will flash once after RB11E detects infrared signal, and
immediately report the status of all current sensor value (voltage, temperature, illuminance).
Report configuration and data sending period.
4.5 IR Delay Configuration
If someone or animal is moving in the monitoring area, RB11E will detect the infrared signal
and the red indicator will flash once. In the mean time, it reports occupied status (at the same
time, other sensor status value are also reported).
To save the power, when RB11E detects the infrared signal, it will enter IRDetectionTime
period. If there is no infrared signal detected in IRDetectionTime period. It will report
un-occupy.
IRDisableTime is the sampling period during IRDetectionTime (IRDisableTime are 30 seconds
by default setting that PIR is off for first 70% of the period; on for rest 30% of the period).
For example, after triggered, the PIR will turn off the infrared probe for 21 (30 * 70%) seconds
to save the power, living objects within this period will not be detected. PIR will re-open
detection function after 21 seconds, if it detects living objects in this period, the IR delay time
will be extended for another 30 seconds till no infrared signal is detected and IRDetectionTime
period is due and RB11E will then report un-occupy.
Note：IRDisableTime >=5 s, IRDetectionTime>= IRDisableTime

5. Restore to Factory Setting
RB11E saves data including network key information, configuration information, etc. To restore to
factory setting, users need to execute below operations.
1. Press and hold function key for 5 seconds till the green indicator flashes and then release; LED
flashes quickly 20 times.
2. RB11E will stay off after restoring to factory setting. Press function key to turn on RB11E and to
join a new LoRa network.
6. Sleeping Mode
RB11E is designed to enter sleeping mode for power-saving in some situations:
(A) While the device is in the network → the sleeping period is 3 minutes. (During this period,
if the reportchange is larger than setting value, it will wake up and send a data report).
(B) When it is not in the network → RB11E will enter sleeping mode and wake up every 15
seconds to search a network to join in the first two minutes. After two minutes, it will wake up
every 15 minutes to request to join the network.
If it’s at (B) status, to prevent this unwanted power consumption, we recommend that users
remove the batteries to power off the device.
7. Low Voltage Alarming
The operating voltage threshold is 3.2V. If the voltage is lower than 3.2V, RB11E will send a
low-power report to the Lora network.
