    Monitor your soils water and temperature condition and improve irrigation scheduling

    It’s easy to know your soil’s water and temperature condition with Monnit’s Soil Moisture Wireless Sensor. It provides a highly effective way to improve irrigation scheduling and efficiency. You’ll know when and where to water your crops, plants, or landscape from the data you gather.


    See water tension to prevent water stress

    The Soil Moisture Sensor measures soil water tension (matric potential) and temperature. With a resistive granular matrix element, you can optimize your tension parameters to determine the earliest indication of water stress and make sure you irrigate before it reaches that point. The unique element feature delivers consistent calibration without needing to recalibrate for every installation.

    The Sensor also has a thermistor-based temperature element. Its readings will help you assess temperature -40°C to 125°C (-40°F to 257°F) and the moisture’s temperature compensation, eliminating the need to measure moisture every time the soil temperature changes.


    Key features of our Soil Moisture Sensor include:

    • Safe and durable in both hot and freezing temperatures
    • Measure within a range of 0 to 240 centibar (cb) or kilopascal (kPa)
    • Corrosion-resistant and made of high-grade stainless steel
    • Internally compensated for commonly found salinity levels
    • Easy to install and use compared to traditional tensiometers
    • Includes a 5-ft. removable lead 

    The sensor’s moisture element is unique because it works similar to a plant’s root by measuring water tension in its hydrophilic fabric-covered matrix material rather than the surrounding soil. 

    The Soil Moisture Sensor has a removable soil moisture/temperature lead and a single sensor base. The sensor works best when you bury the lead or soil probe within or very close to a plant or tree root system. The sensor also works well in most soil types.

    This sensor comes with an industrial battery included with the life of up to 7 years.

    All industrial sensors are enclosed in a reliable, weatherproof NEMA-rated enclosure that are constructed for both indoor and outdoor use. These rugged enclosures protect the sensor circuitry against;

    • Falling dirt
    • Wind-blown dust
    • Rain, sleet, snow, splashing water, and hose-directed water
    • Ice formation on the enclosure
    • Increased resistance to corrosion


    Features

    • 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


    Applications

    • Greenhouse soil monitoring
    • Crop monitoring
    • Smart watering
    • Agronomy research
    • Precision irrigation
    • Forestry
    • Construction
    • Mining


    IMPORTANT - Sensor Operation

    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.

    How to Interpret Data from your Soil Moisture Sensor

    Monnit's Industrial Soil Moisture Wireless Sensor measures soil water status in centibars (cb) or kilopascals (kPa) of soil water tension. This value represents the energy a plant’s root system uses to draw water from the soil. As you analyze and interpret your sensor readings, you gain a clearer view of what is happening with the soil moisture in your crop’s root system.

    Data
    User Interface:

    Soil Moisture: unsigned int, raw / 10 = centibars
    Temperature: signed int, raw / 10 = Celsius


    1 The resolution increases as the centibar readings get lower. Resolution at 0 centibar is ~0.05 centibar, at 240 centibar it is ~0.36 centibar. The sensor is
    limited to 0.1 centibar by the sensor firmware.
    2 Response time calculated by measuring time it takes for sensor to go from fully dry to saturated by placing moisture element upright in 1" of water. Actual
    response times may vary.
    3 Heatshrink adhesive melts at ~85° C. Using at temperatures at or above this level may compromise the waterproofing of the cable and allow the heatshrink
    and sleeve to slip and become loose.
    4 The soil moisture element will not work properly while frozen but when thawed the sensor readings will return to normal.
    5 UI units are user configurable via software.
