MOKO LW007-PIR Infrared Based LoRaWAN PIR Sensor

Introduction

The LW007-PIR is a passive infrared-based LoRaWAN PIR sensor used to detect motion or occupancy. It can detect whether there is movement within the detection range and send this status change via LoRaWAN network.
In addition, it also supports door/window status detection and environment temperature and humidity monitoring functions, making it can be widely used in office, housing, industrial building and other scenarios.

Application Scenarios

Scenario 1: Smart Office
Through the LW007-PIR, user can detect the occupancy of a conference room or other purpose-built space, so that space resources can be arranged in a rational manner. At the same time, the LW007-PIR can also be used to monitor the current ambient temperature and humidity.

Scenario 2: Intelligent Factory
Users can use the LW007-PIR to detect whether someone is on inspection or duty at the corresponding location at the corresponding time to ensure the safety of assets and equipment and production. The device will report the notification to the server, according to which the user can judge the duty situation and the inspection situation and make the corresponding management scheduling.

Scenario 3: Environmental Monitoring
LW007-PIR can realize temperature and humidity monitoring of the environment, and when the temperature (humidity) changes too fast or the temperature (humidity) exceeds the set threshold, alarm information will be issued to realize intelligent monitoring of the environment. It can be mainly applied to computer room/library storage room/document room/hospital ward and other scenarios.

Note: When you use the US915 or AU915 band, the default FSB of the device is FSB2 (CH:8~15).
Step5: Join in LoRaWAN network server.
Please reboot the device, then device will send join request to LoRaWAN server automatically, then you can check the uplink payload on LoRaWAN server.
Step6: Uplink payload parse.
Option 1: You can refer to chapter 7 Uplink Payload, here is the description of the payload parsing rules and samples parsing.
Option 2: MOKOSMART can provide payload decoder code based on some common LoRaWAN network servers.

How to configure device parameters
Users can use the MKLoRa App to configure device parameters and OTA upgrades.
For more configuration details, please refer to document – LW007-PIR APP Guide.

Main Functions

LoRaWAN capabilities
The uplink payloads of LW007-PIR will be transmitted via LoRa and LW007-PIR is based on the standard LoRaWAN protocol V1.0.3.
LW007-PIR is compatible with mainstream gateways and mainstream servers (TTN, SENET, LORA IOT, etc.) in the market.

LoRa uplink transmission strategy
Considering the load balance of the gateway, the battery power consumption and the reliability of the messages, the LW007-PIR is equipped with a LoRa uplink mechanism for users to choose, so that users can select a suitable sending strategy according to different application scenarios.

Confirmed message retransmission mechanism
Because the application scenario of this product requires high success in data transmission, the uplink payload is transmitted by default via confirmed message. When the device transmits data via confirmation message, if the data is not successfully reported, it can be retransmitted through the protocol layer, and the number of retransmissions can be set.

LinkCheck function
LW007-PIR supports the LinkCheck feature, which can check the LoRaWAN network connection status.
The user can set the LinkCheck interval via MKLoRa or LoRaWAN downlink command.
The LW007-PIR will check its network status periodically at this interval. If network check fails, network check process will be initiated again every 10s, if the network detection fails three times in a row, the device will rejoin the LoRaWAN network.

DeviceTime function
LW007-PIR supports the DeviceTime feature, which enables users to periodically time their devices to avoid time offset.
The Time Sync Interval of the MKLoRa APP is the Device Time MAC Command interval.

Occupancy detection
With the built-in PIR sensor and Fresnel lens, the occupancy and movement behavior of the monitoring area can be monitored.
When the space occupation status changes, the device will report Information Payload to the server.
At the same time, if the space occupancy status is continuously occupied, the device will report Information Payload to the server regularly to notify the occupancy status.

PIR detection range description：

Door/Window status detection
LW007-PIR can be mounted on any doors/windows to detect an opening or closing event. When these events occur, LW007 will report Information Payload to sever thus enabling security monitoring of the space.
This function can be used in conjunction with the occupancy detection function, making the results of occupancy detection more accurate and reliable. When someone opens a room door and enters, both the door detection status and the occupancy status change, allowing the user to determine the current occupancy of the space.

Note: When using the PIR function in conjunction with window status detection, ensure that no curtains, screens or other objects obstruct the PIR detection area.

Temperature and humidity monitoring
LW007-PIR Built-in high-precision sensors and exterior ventilation holes design, can quickly and accurately sense temperature and humidity changes.
The product can set temperature threshold alarm, temperature over limit alarm, humidity threshold alarm, humidity over limit alarm and other functions, which can realize timely alert and notification of abnormal temperature and humidity in the monitoring area, so that customers can deal with abnormal situations quickly.

Heartbeat mechanism
The device will report Heartbeat Payload at regular intervals.
If another Payload is uploaded during the heartbeat interval, the heartbeat upload interval will be refreshed.
Users can set different heartbeat reporting intervals according to the actual application scenario to ensure network stability.

Battery performance
The LW007-PIR is equipped with 2*AA non-rechargeable battery (ER14505).
According to the operating voltage requirement of each component, the total actual power available is about 4000mAh.
Based on this actual power capacity, the endurance of the device is about 5 years under typical scenarios (Each day: Trigger PIR detection 20 times, Trigger door detection 20 times, uplink 40 information payloads by SF10)
When the battery runs out, user can replace the battery with the same type and size.

Low battery alert
When LW007-PIR’s battery level is low, its LED indicator will flash red every 10s and it will report Heartbeat Payload to the server as a prompt immediately.
Note: Low battery threshold can be to set 5% and 10%. User can also choose not to report the Heartbeat Payload when the device’s battery level is low.

On/OFF
Users can switch the device on and off by press and hold the power button on the side of the device for 3s.
In additional, LW007-PIR supports sending the shutdown payload as a notification alert when the device is turned off. Users can choose to turn off this feature.
Note: If the battery is suddenly disconnected or pulled out, the device cannot send the Shutdown Payload.

Restore to factory setting
There are two ways to restore to factory setting:

1. Through the physical button, Click the reset button on the back of the location device by tools.
2. User can send LoRaWAN downlink commands to make the plug restore to factory setting via LoRaWAN server.

Time synchronization
There are two methods to sync time of LW007-PIR.

1. LW007-PIR supports the DeviceTimeReq MAC Command, which enables users to periodically time their devices to avoid time offset.
2. When the device is successfully connected to MKLoRa app, the time of host device will be synced to the device immediately.

Bluetooth configuration tool
The device can use MKLoRa app developed by MOKO for quick OTA upgrades and parameter configuration via Bluetooth connection. About the detail of MKLoRa, pls refer to LW007-PIR APP Guide.
