    A smart way to monitor H2S in the workplace

    Hydrogen Sulfide (H2S) is a toxic gas that stalks underground telecom vaults and many other enclosed industrial, agricultural, and commercial areas. Highly flammable, H2S also gravitates to ignition sources, posing a risk of flashbacks or explosions.

    The Monnit Enterprise Hydrogen Sulfide Gas Wireless Sensor measures the levels of toxic H2S gas in the environment. The sensor produces instantaneous and 8-hour time weighted average (TWA) H2S readings along with temperature. Every five seconds the sensor takes a new temperature-compensated H2S measurement and checks this measurement against a configurable threshold. If the threshold is crossed, the sensor transmits data immediately. This means the sensor can report a critical gas level as soon as it's detected. If the threshold isn't crossed, the sensor transmits H2S data at a configurable Heartbeat. Using configurable Actions within iMonnit Software, you can set up notifications to be sent via text, email, and phone call as different triggering events occur - gas level, battery level, inactivity, etc. The instantaneous reading is calculated using 40 seconds of data averaged together for improved stability and accuracy. The TWA reading is calculated using eight hours of data.

    This sensor come standard with two replaceable AA batteries. The typical battery life is approximately 10 years.


    Features

    • Measures H2S levels in surrounding air
    • Provides instantaneous and TWA H2S readings
      • Works within excellent range (0 to 50 ppm)
      • Offers configurable thresholds
      • Responds in less than one minute
    • Impressive wireless range of up to 1,200 feet through walls
    • Frequency-hopping spread spectrum (FHSS)
    • Improved interference immunity
    • Improved power management for longer battery life
    • Encrypt-RF® Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
    • Stores 2000 to 4000 readings if gateway connection is lost (non-volatile flash, persists through the power cycle)
      • 10-minute heartbeats = ~ 22 days
      • 2-hour heartbeats = ~ 266 days
    • Over-the-air updates
    • Free iMonnit basic online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email

    Monnit Gateway Options

    An integral component of any IoT network is the gateway. A gateway device allows for data from sensors to be transmitted to the iMonnit software platform.


    Monnit Ethernet Wireless Gateway 4

    Monnit’s Ethernet Gateways allow your Monnit Wireless Sensors to communicate with the iMonnit™ Online Wireless Sensor Monitoring and Notification System without the need for a PC. Simply provide power and plug the gateway into an open Ethernet network port with an internet connection. It will then automatically connect with our online servers, providing the perfect solution for commercial locations where there is an active internet connection.

    Monnit 4G + Ethernet IoT Gateway

    The ALTA® by Monnit Wireless IoT Gateway combines a 4G LTE CAT-M1/NB2 cellular engine and Ethernet platform with Monnit’s wireless access point network to aggregate and communicate data from Monnit ALTA Wireless Sensors. The ALTA IoT Gateway allows ALTA Sensors to operate on the world’s leading cellular networks and stay connected to the Internet. The gateway uses AC main power but also has redundant power through a battery backup lasting up to 60 hours.

    To meet the global demand for enterprise IoT deployment, the IoT Gateway communicates with the cloud-based iMonnit® monitoring software via cellular transmission, making it ideal for remote locations or where the Internet isn’t available. The RJ-45 Ethernet jack allows local device configuration, diagnostics, and connectivity backup. The IoT Gateway is instrumental in sending sensor notifications via text, email, or call if user-defined conditions are met or exceeded.
