3. Delete low power alarm interval, the device only uplinks once when the battery level is lower than 10%.

Product Introduction

Overview

WS202 is a PIR sensor based on passive infrared technology to detect a motion or occupancy.
WS202 can detect whether there is a movement within the range of 6-8 m. Besides, WS202 equips with a light sensor that can link PIR detection results to trigger scenes.  WS202 can be widely used in smart homes, smart offices, schools, warehouses, etc.

Sensor data are transmitted in real-time using the standard LoRaWAN® protocol. LoRaWAN® enables encrypted radio transmissions over long distances while consuming very little power. The user can get an alarm through Milesight IoT Cloud or through the user’s own Application Server.

Features

• Built-in light sensor, combine PIR sensor to achieve triggers
• Up to 15 km communication range
• Easy configuration via NFC
• Standard LoRaWAN® support
• Compatible with Milesight IoT Cloud

Operation Guide

NFC Configuration

WS202 can be configured via an NFC-enabled smartphone.

1. Pull out the battery insulating sheet to power the device. The indicator will light up in green for 3 seconds when the device turns on.

2. Download and install the “Milesight ToolBox” App from Google Play or App Store.

3. Enable NFC on the smartphone and open Milesight ToolBox.

4. Attach the smartphone with an NFC area to the device to read device information.

5. Basic information and settings of the device will be shown on ToolBox if it’s recognized successfully. You can read and configure the device by tapping the Read/Write device on the App. In order to protect the security of the device, password validation is required when configuring a new smartphone. The default password is 123456.

Note:

1. Check the location of the smartphone NFC area and it’s recommended to take off the phone case.
2. If the smartphone fails to read/write configurations via NFC, move the phone away and back to try again.
3. WS202 can also be configured by ToolBox software via a dedicated NFC reader provided by Milesight IoT, you can also configure it via the TTL interface inside the device.

LoRaWAN Settings

LoRaWAN settings are used for configuring the transmission parameters in the LoRaWAN® network.

Basic LoRaWAN Settings:

Go to Device - > Setting -> LoRaWAN Settings of ToolBox App to configure join type, App EUI, App Key, and other information. You can also keep all settings by default.

port is 85.
Join Type| OTAA and ABP modes are available.
Application Key| Appkey for OTAA mode, default is 5572404C696E6B4C6F52613230313823.
Device Address| Devendra for ABP mode, the default is the 5th to 12th digits of SN.
Network Session Key| Nwkskey for ABP mode, default is 5572404C696E6B4C6F52613230313823.
Application Session Key| Appskey for ABP mode, default is 5572404C696E6B4C6F52613230313823.
Spread Factor| If ADR is disabled, the device will send data via this spread factor.
Confirmed Mode| If the device does not receive an ACK packet from a network server, it will resend
data 3 times at most.
Rejoin Mode| Reporting interval ≤ 30 mins: the device will send specific mounts of LoRaMAC
packets to check connection status every 30 mins; If no reply after specific
packets are being sent, the device will re-join.
Reporting interval > 30 mins: the device will send specific mounts of LoRaMAC
packets to check connection status at every reporting interval; If no reply after specific packets are being sent, the device will re-join.
ADR Mode| Allow the network server to adjust the data rate of the device.
Tx Power| Transmit power of the device.

Note:

1. Please contact the sales representative for the device EUI list if there are many units.
2. Please contact the sales representative if you need random App keys before purchase.
3. Select OTAA mode if you use Milesight IoT Cloud to manage devices.
4. Only OTAA mode supports rejoin mode.

LoRaWAN Frequency Settings:
Go to Setting- >LoRaWAN Settings of ToolBox App to select the supported frequency and select channels to send uplinks. Make sure the channels match the LoRaWAN® gateway.

If the device frequency is one of CN470/AU915/US915, you can enter the index of the channel that you want to enable in the input box, making them separated by commas.

Examples:
1, 40: Enabling Channel 1 and Channel 40
1-40: Enabling Channel 1 to Channel 40
1-40, 60: Enabling Channel 1 to Channel 40 and Channel 60
All: Enabling all channels
Null: Indicates that all channels are disabled

Note:
For the -868M model, the default frequency is EU868;
For the -915M model, the default frequency is AU915.

General Settings

Go to Device->Setting->General Settings of ToolBox App to change the reporting interval, etc.

level to a network
server. Default: 30 mins, Range: 1 – 1080 mins
Note: WS202 will also report the “triggered” status of the PIR sensor immediately
when it detects motions.
Idle Time| When the PIR sensor does not detect motion for a period of Idle Time,
Reporting/s| the device will report a “not triggered” status. Default: 120 s
LED Indicator| Enable or disable the light indicated in chapter 2.4.
Note: The indicator of the reset button is not allowed to be disabled.
Illuminance
Collection| Enable or disable illuminance collection. When this is disabled, reporting the interval will be changed to 1080 mins automatically.
Change Password| Change the password for ToolBox App to write this device.

Threshold Settings

When illuminance collection is enabled, users can define the Bright or Dark state via detection data of the light sensor in threshold settings. Besides, when the PIR sensor is triggered and light status meets the threshold, WS202 will send alarms immediately. Otherwise, it will not send data right away.

LoRa D2D Settings

Lora D2D protocol is developed by Milesight and used for setting up transmission among Milesight devices without a gateway. When the LoRa D2D setting is enabled, WS202  can work as a LoRa D2D controller to send control commands to trigger LoRa D2D agent devices.

1. Enable the LoRa D2D feature.

2. Define a unique LoRa D2D key that is the same as LoRa D2D agent devices, then select the frequency and spreading factor. (Default LoRa D2D Key:  572404C696E6B4C6F5 2613230313823)

3. Enable one of WS202 status and configure a 2-byte hexadecimal command (This command is pre-defined in LoRa D2D agent device). When WS202 detects this status, it will send the control command to corresponding LoRa D2D agent devices.
   Note: When this feature is enabled, the device will not send data to the LoRaWAN® network server if WS202 PIR or light status changes.
