Product Introduction 1.1 Overview WS302 is a LoRaWAN� sound level sensor with an integrated microphone. WS302 can not only measure a wide range of noise levels and send various kinds of noise level values via LoRaWAN� network, but also supports multiple weighting measurements for different application scenarios. WS302 can be widely used in smart buildings, smart cities, schools, health monitoring, 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 obtain sensor data and view the trend of data change through Milesight IoT Cloud or through the user's own Application Server. 1.2 Features Robust LoRa connectivity for secure long range transmission Support multiple weighting measurements to suit different scenes Support measuring various kinds of values to judge the sound level accurately Easy configuration via NFC Equipped with LED indicator to indicate the threshold alarm Standard LoRaWAN� supported Milesight IoT Cloud compliant 2.

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. Parameters Device EUI App EUI Application Port Join Type Application Key Device Address Network Session Key Application Session Key Spread Factor Confirmed Mode Rejoin Mode Description Unique ID of the device which can also be found on the label. Default App EUI is 24E124C0002A0001. The port used for sending and receiving data, default port is 85. OTAA and ABP modes are available. Appkey for OTAA mode, default is 5572404C696E6B4C6F52613230313823. DevAddr for ABP mode, default is the 5th to 12th digits of SN. Nwkskey for ABP mode, default is 5572404C696E6B4C6F52613230313823. Appskey for ABP mode, default is 5572404C696E6B4C6F52613230313823. If ADR is disabled, the device will send data via this spread factor. If the device does not receive ACK packet from network server, it will resend data once. Reporting interval 30 mins: the device will send a specific number of LinkCheckReq MAC packets to the network server every 30 mins to validate 8 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 LinkCheckReq 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 When rejoin mode is enabled, set the number of LinkCheckReq packets sent. packets sent ADR Mode Allow network server to adjust datarate of the device. RX2 Data Rate RX2 data rate to receive downlinks. RX2 Frequency/MHz RX2 frequency to receive downlinks. Note: 1) Please contact sales for device EUI list if there are many units. 2) Please contact sales 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. 4.3 Basic Settings Go to Device Setting -> Basic -> Basic Settings of ToolBox App to change the reporting interval, etc. Parameters Description Reporting interval of noise level and battery level to the network server. Reporting Interval Default: 10 mins, Range: 1 - 1080 mins LED Indicator Enable or disable the indicator threshold alarm feature in chapter 2.3. Frequency Choose A weighting or C weighting to detect environmental sound. 9 Weighting A-weighting: suitable for normal environment like office, hospital, residential, etc. C-weighting: suitable for noisy environment (> 100dB) like factories, construction yards, dancing halls, etc. Fast Time Weighting Enable or disable fast time weighting, this suit the environment in which sound has great fluctuation.
