Its four-in-one sensing platform also measures temperature and humidity, while configurable alarms, a built-in buzzer, status indicator and Milesight D2D connectivity support automated ventilation and smart facility-management applications.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eFour-in-one environmental monitoring:\u003c\/strong\u003e Measures ammonia, hydrogen sulphide, temperature and relative humidity from a single compact device.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eAmmonia detection:\u003c\/strong\u003e Solid polymer electrochemical sensing measures NH₃ concentrations from 0 to 10 ppm with 0.01 ppm resolution.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eHydrogen sulphide detection:\u003c\/strong\u003e Measures Hâ‚‚S concentrations from 0 to 5 ppm with a fine 0.001 ppm resolution.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eConfigurable threshold alarms:\u003c\/strong\u003e High gas concentrations can trigger the integrated status indicator, buzzer and LoRaWAN uplink to help staff respond to changing conditions.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eMilesight D2D:\u003c\/strong\u003e Enables direct low-latency communication with compatible Milesight devices for applications such as automatic ventilation control without relying on a gateway for the D2D control path.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eLoRaWAN connectivity:\u003c\/strong\u003e Provides long-range, low-power wireless communication with compatible LoRaWAN gateways and network servers.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eMulti-year battery operation:\u003c\/strong\u003e Four replaceable 4000 mAh Li-SOClâ‚‚ batteries provide around three years of operation under Milesight's specified test conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e\u003cimg src=\"https:\/\/www.lockstok.com\/\/ProductImages\/Milesight\/67339515-2117-4575-BE3B-55A83CB8D401_424861.jpg?1787237391022\"\u003e\u003c\/h3\u003e\n\n\u003ch3\u003eFour-in-One Bathroom Environment Monitoring\u003c\/h3\u003e\n\n\u003cp\u003eThe GS301 combines ammonia, hydrogen sulphide, temperature and humidity sensing in one device. Ammonia and hydrogen sulphide are common contributors to unpleasant washroom odours, allowing the sensor to provide measurable information that can support more responsive cleaning and ventilation strategies.\u003c\/p\u003e\n\n\u003ch3\u003eAmmonia and Hydrogen Sulphide Detection\u003c\/h3\u003e\n\n\u003cp\u003eSolid polymer electrochemical sensing provides a 0 to 10 ppm measurement range for ammonia and a 0 to 5 ppm range for hydrogen sulphide. Both gas sensors have a specified accuracy of ±5% FS between -40°C and 35°C, while resolutions of 0.01 ppm for NH₃ and 0.001 ppm for Hâ‚‚S support detailed concentration monitoring. Milesight recommends operating the gas sensors below 35°C.\u003c\/p\u003e\n\n\u003ch3\u003eThreshold Alarms and Ventilation Control\u003c\/h3\u003e\n\n\u003cp\u003eCustomisable thresholds allow the GS301 to react when ammonia or hydrogen sulphide concentrations reach configured levels. Events can activate the built-in buzzer and status indicator while transmitting data through LoRaWAN. Milesight D2D can additionally communicate directly with compatible Milesight equipment with a response time below one second, supporting applications such as automated ventilation control.\u003c\/p\u003e\n\n\u003ch3\u003eLoRaWAN Connectivity\u003c\/h3\u003e\n\n\u003cp\u003eThe GS301 is compatible with standard LoRaWAN gateways and network servers and supports OTAA and ABP activation in Class A mode. Milesight specifies transmission distances of up to 2 km in urban areas and up to 15 km in rural areas, although actual wireless range depends on buildings, interference, gateway placement and other deployment conditions. NFC provides convenient local configuration using the Milesight ToolBox mobile application.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\n\u003ctable
