IMPORTANT – Sensor Operation

Please note: this sensor requires both an applicable Gateway and iMonnit software to operate. For further information, please refer to the tabs above or related products below.

  • OVERVIEW

    Detect & defend from water damage

    The sensor detects when water is present by completing the circuit between the two wires at the end of the water detection lead. When the detection state changes the sensor will immediately turn on the RF radio and transmit the data to the wireless gateway and iMonnit Online Sensor Monitoring and Notification System, allowing the user to immediately receive an SMS text or email alert. The sensor can be set to go aware when the detection state changes, water is present, or water is absent. If the sensor sends an aware message, it can trigger the gateway to forward the data to iMonnit immediately, otherwise the data will be forwarded when the gateway talks to the server on its heartbeat or when triggered by another sensor. The sensor can be configured to detect both the presence and absences of water.

    Protect your facility with early detection

    Instant alerts from Monnit’s Water Detect Plus Sensors help defend against weather, faulty plumbing, and equipment failure. In addition to detection, the sensors monitor for water’s absence—helpful for sanitation and remediation.

    Detect plus sensor employs a wall- or surface-mountable probe at the end of a 3’ lead to detect the water’s presence (or absence). The probe is often used in sanitation or process applications to detect levels in reservoirs or vats of non-combustible liquid. The Detect Plus probe helps minimize false alarms when mounted to compensate for expected variables, e.g., condensation.

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

    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)
    • 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
    • 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

    Applications

    • Data Centre and service room leak monitoring
    • Frozen or burst pipe monitoring
    • Reservoir level monitoring
    • Water heater leak detection
    • Sink and toilet leak detection
    • Storage unit monitoring
    • Water intrusion monitoring
