Wireless Water Detection Puck Sensor, White




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

Features of Monnit ALTA Sensors:

- Wireless range of 2,000+ feet through 18+ walls

- Frequency-Hopping Spread Spectrum (FHSS)

- Best-in-class interference immunity

- Best-in-class power management for longer battery life

- 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
