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 canbewidely used in smart homes, smart offices, schools, warehouses, etc.

Sensor data are transmitted in real-time using the standard LoRa WAN® protocol. Lora WAN ®enables encrypted radio transmissions over long distances while consuming very little power. The user can get an alarm through Mile sight IoT Cloud or through the user’sown Application Server.

Features
  • Built-in light sensor, combine PIR sensor to achieve triggers
  • Up to 15 km communication range
  • Easy configuration via NFC
  • Standard Lora WAN ® support
  • Compatible with Mile sight Iota 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.
    NFC Configuration

  2. Download and install “Mile sight Toolbox” App from Google Play or App Store.

  3. Enable NFC on the smartphone and open Mile sight Toolbox

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

  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 requiredwhenconfiguring via a new smartphone. The default password is 123456.

General Settings

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

Parameters Description
Reporting Interval The interval of reporting PIR, light status and battery

level to network server. Default: 30 mins, Range: 1 – 1080 minsNote: WS202 will also report “Occupied” status immediately when itdetects motions.
Idle TimeReporting/s| When the PIR sensor does not detect motion for a period of Idle Time,device will report “Vacant” 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.
IlluminanceCollection| Enable or disable illuminance collection. When this is disabled, reportinginterval 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 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 senddataright away.
General Settings

Milesight D2D Settings

Milesight D2D protocol is developed by Milesight and used for setting up transmissionamongMilesight devices without gateway. When the Milesight D2D setting is enabled, WS202 canworkas a Milesight D2D controller to send control commands to trigger Milesight D2D agent devices.

  1. Configure RX2 datarate and RX2 frequency in LoRaWAN® settings, it is suggested tochangethe default value if there are many LoRaWAN® devices around.

  2. Go to Device > Settings > D2D Settings to enable D2D function, and define an uniqueMilesight D2D key which is the same as Milesight D2D agent devices, then select the frequencyand spreading factor. (Default Milesight D2D Key: 5572404C696E6B4C6F52613230313823)
    Milesight D2D Settings

  3. Enable one of WS202 status and configure a 2-byte hexadecimal command (This commandis pre-defined in Milesight D2D agent device). When WS202 detects this status, it will sendthecontrol command to corresponding Milesight D2D agent devices.
    Milesight D2D Settings

Note: If you enabled LoRa Uplink feature, LoRaWAN® uplink that contains the PIR statusandlight status will be sent to gateway after Milesight D2D control command is sent

Reset to Factory Default

Please select one of the following methods to reset device:

Via   Hardware: Hold on the reset button for more than 10s. After reset complete, the indicator will blink in green twice, then device will reboot.
Via ToolBox App: Go to Device > Maintenance to tap Reset, then attach smartphone withNFCarea to device to complete reset.

For applications requiring detection angle control, such as work station, in order to prevent
accidental detection of people around the station, please paste the blocking stickers on the sensor along the bottom of the PIR lens for range shielding. Each sticker can cover about a180°range. After paste the stickers along the bottom of the lens and wrapping the sensor 360°, the detection area has changed to 70° Horizontal, 60° Vertical.

Note: The detection area may be affected by manual pasting, potentially introducing errors.
