Wireless Water Detection Puck Sensors
The ALTA Wireless Water Detection Puck Sensor detects the presence or non-presence of water
The ALTA Wireless Water Detection Puck Sensor detects the presence or non-presence of water. Convenient water tight puck design allows the sensor to be placed anywhere needed whether dry or wet. Note that water levels must be ~ 3mm deep to trigger detection.
Water Detection
• Water proof/fully submersible.
• Immediately detects water presence.
Principle of Operation
The ALTA Wireless Water Detection Puck Sensor detects when water is present by completing the circuit between the two probe points on the bottom of the puck sensor. When water is present the sensor will immediately turn on the 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 configured to detect both the presence and non-presence of water.
Features of Monnit ALTA Sensors
• Wireless range of 1,200+ feet through 12+ walls *
• Frequency-Hopping Spread Spectrum (FHSS)
• Improved interference immunity
• Improved power management for longer battery life **(12+ years on AA batteries)
• Encrypt-RF® Security (Diffie-Hellman Key Exchange+AES-128 CBC for sensor data messages)
• Onboard data memory stores up to 512 readings per sensor:
- 10-minute heartbeats = 3.5 days
- 2-hour heartbeats = 42 days
• Over-the-air updates (future proof)
• Free iMonnit basic online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email
*Actual range may vary depending on environment.
**Battery life is determined by sensor reporting frequency and other variables. Other power options are also available.
