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, WS202equips with a light sensor which 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. Lo Ra WAN® enables encrypted radio transmissions over long distances while consuming very little power. The user can get an alarm through Milesight Io T 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 on the device. The indicator will light upingreenfor3seconds when the device turns on.
2. Download and install “Milesight Tool Box” App from Google Play or App Store.
3. Enable NFC on the smartphone and open Milesight Tool Box.
4. Attach the smartphone with NFC area to the device to read device information.
5. Basic information and settings of the device will be shown on Tool Box 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 via a new smartphone. The default password is 123456.
Note:
-
Check the location of the smartphone NFC area and it’s recommended to take off the phone case.
-
If the smartphone fails to read/write configurations via NFC, move the phone away and back to try again.
-
WS202 can also be configured by Tool Box software via a dedicated NFC reader provided by Milesight Io T, you can also configure it via TTL interface inside the device.
LoRaWAN Settings
LoRaWAN settings are used for configuring the transmission parameters in LoRaWAN® network.
Basic LoRaWAN Settings:
Go to Device - > Setting -> LoRaWAN Settings of Tool Box App to configure
join type, App EUI, App Key and other information. You can also keep all
settings by default.

Parameters
|
Description
---|---
Reporting Interval| The interval of reporting PIR, light status and battery
level to network kserver. Default: 30 mins, Range: 1 – 1080 mins
Note: WS202 will also report “triggered” status of 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| device will report “not triggered” status. Default: 120 s
LED Indicator| Enable or disable the light indicating in chapter 2.4.
Note: The indicator of reset button is not allowed to disable.
Illuminance Collection| Enable or disable illuminance collection. When this is disabled, reporting
interval will be changed to 1080 mins automatically.
Change Password| Change the password for Tool Box App to write this device.
Threshold Settings
When illuminance collection is enabled, users can define the Bright or Dark state via detection data of 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 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 LoRa D2D feature.
2. Define a unique LoRa D2D key which is the same as LoRa D2D agent devices, then select the frequency and spreading factor. (Default LoRa D2D Key: 5572404C696E6B4C6F52613230313823)
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 LoRaWAN® network server if WS202 PIR or light status changes.
