Water Detection

Water Detect & Detect+ General Description

ALTA® Wireless Water Detect and Detect+ Sensors report the presence or absence of water and are available with various lead options.

Key Features

• Immediately detects water

• Lead length options:

• - 0.9 m (3') Standard, 3 m (10'), 7.5 m (25'), 5 m (50'), 30 m (100')

• - Lead or probe options:

• Detect: bare-wire lead

• Detect+: stainless steel probe

Principles of Operation

ALTA Wireless Water Detect and Detect+ Sensors identify when water is present by completing a circuit between the two contacts at the end of the lead. When the detection state of the sensor changes, wireless communication is immediately sent to the gateway. The communications can be configured to be sent urgently or as an awareness notification when:

• Water is present

• Water is absent

• Water is present or absent

If the communication is not marked urgent, the data will bestored and scheduled to be forwarded by the gateway later. If the communication is marked urgent, the gateway will immediately attempt to securely send the message to iMonnit, or other approved data services.

Water Rope General Description

ALTA® Wireless Water Rope Sensors detect the presence of water anywhere along the surface of the rope.

Key Features

• Immediately detects water anywhere along the rope

• 3 meters (10') of lead and water detection rope

• Expandable up to 30 meters (100') of detection rope

Principles of Operation

The ALTA Wireless Water Rope Sensors detect conductive liquids anywhere along the length of the detection rope by using two wires covered with conducting polymer. When water or conductive liquid contacts the rope, a wireless communication is immediately sent to the gateway. The communications can be configured to be sent urgent or "aware" when:

• Water is present

• Water is absent

• Water is present or absent

If the communication is not marked urgent, the data will be stored and scheduled to be forwarded by the gateway at a later time. If the communication is marked urgent, the gateway will immediately attempt to securely send the message to the iMonnit, or other approved data services. The sensor rope quickly dries so it can reset. You can expand the detection rope up to 30 meters (100') by simply connecting additional 3-meter (10') sections.

Water Detection Puck General Description

ALTA® Wireless Water Detection Puck Sensors report the presence or absence of water. The convenient water tight puck design allows the sensor to be placed anywhere it's dry or wet. Note: water levels must be ~ 1.6mm high to trigger detection.

Key Features

• Immediately detects water presence

• Waterproof and fully submersible

Principles of Operation

The ALTA Wireless Water Detection Puck Sensors detect when water is present by completing a circuit between the two probe points (exposed stainless steel metal screw heads) on the bottom of the sensor. When the detection state of the sensor changes (water present or absent), a wireless communication is immediately sent to the gateway. The communications can be configured to be sent urgent or "aware" when:

• Water is present

• Water is absent

• Water present or absent

If the communication is not marked urgent, the data will be stored and scheduled to be forwarded by the gateway at a later time. If the communication is marked urgent, the gateway will immediately attempt to securely send the message to iMonnit, or other approved data services.

Features of Monnit ALTA Sensors

• Wireless range of 2,000+ feet through 18+ walls1

• Frequency-Hopping Spread Spectrum (FHSS)

• Best-in-class interference immunity

• Best-in-class power management for longer battery life2

• Encrypt-RF® Security (Diffie-Hellman Key Exchange + Advanced Encryption Standard (AES)-128 Cipher Block Chaining (CBC) for sensor data messages)

• Sensor logs 2000 to 4000 readings if the gateway connection is lost (non-volatile flash, persists through power cycling):

• 10-minute Heartbeats = ~ 22 days

• 2-hour Heartbeats = ~ 266 days

• Automatic over-the-air updates to sensor firmware (future-proof)

• Free iMonnit Basic Online Wireless Sensor Monitoring and Notification System to configure sensors, view data, and send alerts via SMS text, email, and voice call

1 Actual range may vary depending on the environment and gateway.
2 Battery life is determined by the sensor reporting frequency and other variables. Other power options are also available
