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 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.

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 up in green for 3 seconds when 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 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. The default password is 123456.

Note:

1. Check the location of the 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 a dedicated NFC reader provided by Milesight IoT, you can also configure it via 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.

Spread Factor| If ADR is disabled, the device will send data via this spread factor.

Confirmed Mode

| If the device does not receive 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

Note:

1. Please contact sales representative for the device EUI list if there are many units.
2. Please contact 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 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
