Quick Guide

If any of the above items is missing or damaged, please contact your sales representative.

1.1 Overview

WS202 is a PIR sensor based on passive infrared technology to detect a motion or occupancy.

WS202 can detect whether there is movement within the range of 6-8 m. Besides, WS202 equips

with light sensor which can link PIR detection results to trigger scenes. WS202 can be widely us

ed 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 alarm through Milesight IoT Cloud or through the user's own

Application Server.

1.2 Features

3. Operation Guide

3.1 NFC Configuration

WS202 can be configured via NFC-enabled smartphone.

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

seconds when device turns on.

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

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

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 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 via a new smartphone. Default password is 123456.

Note:

1) Check the location of smartphone NFC area and it’s recommended to take off 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 dedicated NFC reader provided by

Milesight IoT, you can also configure it via TTL interface inside the device.

3.2 LoRaWAN Settings

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