1. Product Introduction
1.1 Overview
GS301 is a 4-in-1 LoRaWAN®bathroom odor detector to detect ammonia (NH3) and hydrogen
sulfide (H2S) gas according to electrochemical principle. GS301 is also able to detect
temperature and humidity to fully aware of the environment of bathrooms. When the NH3or H2S
gas concentration reaches the preset threshold, the detector will trigger both LED light alarm and
buzzer to notify people timely to ventilate, which is an important part in smart bathroom
solution.
Apart from local alarms, GS301 can also report the sensor data and alarm messages remotely
using LoRaWAN®technology. Integrating with Milesight LoRaWAN®gateway and Milesight IoT
Cloud solution, users can monitor all the sensor data and control the deice remotely and flexibly.
Moreover, GS301 supports Milesight D2D to enable ultra-low latency control without gateways.
1.2 Features
Built-in high accuracy electrochemical gas detection sensor with more than 3-year-long life
expectancy
Built-in multiple sensors including NH3, H2S, temperature and humidity
Built-in batteries to achieve wireless power supply and decrease in installation cost
Equipped with buzzer and LED indicator to indicate threshold alarms
Damp proof coating inside the device to ensure device working well on various conditions of
bathrooms
Support Milesight D2D protocol to enable ultra-low latency and direct ventilation control
without gateways
Built-in NFC for easy configuration
Compatible with standard LoRaWAN®gateways and network servers
Quick and easy management with Milesight IoT Cloud solution

3. Operation Guide
3.1 Basic Configuration
1. Long press and hold the power button for more than 3 seconds to power on the device. After
powering on or rebooting, wait for about 30 minutes for sensor polarization process. Only when
the polarization completes, the device can collect NH3and H2S data.
2. Download and install “Milesight ToolBox” App from Google Play or Apple App Store.
3. Enable NFC on the smartphone and launch Milesight ToolBox.
4. Attach the smartphone with the NFC area to the device to read device information. Basic
information and settings of the device will be shown on ToolBox App if it’s recognized
successfully. You can read and configure the device by tapping the Read/Write device on the
App. To order to protect the security of the device, please change the password when first
configuration. The default password is 123456.
Note:
1) During polarization process, temperature and humidity data will be collected as usual, NH3
7
and H2S values will be shown 655.34 ppm on ToolBox page.
2) Ensure the location of smartphone NFC area and it’s recommended to take off phone case.
3) If the smartphone fails to read/write configurations via NFC, keep the phone away and back
to try again.
4) GS301 can also be configured by a dedicated NFC reader, which can be purchased from
Milesight IoT.
