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.
   

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.
   

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.

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 andbackto try again.
3. WS202 can also be configured by Tool Box software via a dedicated NFC reader provided by Mile sight Iota, you can also configure it via TTL interface inside the device.

LoRa WAN Settings

Go to Device > Setting > LoRa WAN Settings of ToolBox App to configure join type, App EUI, AppKey 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 network server, it will resenddata once.
Rejoin Mode| Reporting interval ≤ 30 mins: the device will send a specific number of LinkCheckReq MAC packets to the network server with periodic or threshold uplinks every time more than 25~35 mins passes to validate connectivity; If there is no response, the device will re-join the network.Reporting interval > 30 mins: the device will send a specific number of Link Check Req MAC packets to the network server every reporting interval to validate connectivity; If there is no response, the device will re-join the network.
Set the number of packets sent| When join mode is enabled, set the number of LinkCheckReq packets sent.Note: the actual sending number is Set the number of packet sent + 1.
ADR Mode| Allow network server to adjust data rate of the device. This only works with Standard Channel Mode.

1. Please contact sales representative for 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 Mile sight IoT Cloud to manage devices.
4. Only OTAA mode supports rejoin mode.

General Settings

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

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.

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)
   

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.
   

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

Maintenance

Upgrade

1. Download firmware from Mile sight website to your smartphone.
2. Open Tool Box App and click “Browse” to import firmware and upgrade the device.
   

Backup

WS202 supports configuration backup for easy and quick device configuration in bulk. only for devices with the same model and Lo Ra WAN® frequency band

1. Go to Template page on the App and save current settings as a template. You can alsoedit
   the template file.

2. Select one template file that saved in the smartphone and click Write, then attach it to another device to write configuration.

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.

3M Tapes Fix:
Paste 3M tape to the back of the device, then tear the other side and place it on a flat surface

Screw Fix:
Remove the back cover of the device, screw the wall plugs into the wall and fix the cover withscr ews on it, then install back the device.

Note:

1. Adjust the installation direction according to detection area requirement.
2. WS202 can be mounted on a wall or ceiling. It’s recommended to install at 1.5~2.5mfromthefloor.
3. Ensure the detection area does not have moving objects like waving trees and fans.
4. Ensure the detection area is not blocked by

Sensor Data

WS202 reports sensor data and battery level according to reporting interval (30 mins by default)
or when PIR/light status changes. Besides, when battery level is lower than 10%, it will uploadbattery packet once.

Example:

Downlink Commands

WS202 supports downlink commands to configure the device. The application port is 85 by default.

Example:

1. Set reporting interval as 20 minutes
   ff03b004

   Channel| Type| Value
   ff| 03 (Set Reporting Interval)| b0 04 => 04 b0 = 1200s= 20 minutes

2. Reboot the device
