by The Leading Enterprise Internet of Things Solution Wireless Duct Temperature Sensors General Description Features of Monnit ALTA Sensors The ALTA Wireless Duct Temperature Sensor uses Wireless range of 1,200+ feet through 12+ walls * an NTC thermistor with 8 ft lead wires to accurately Frequency-Hopping Spread Spectrum (FHSS) measure temperatures in duct work, while maintaining Improved interference immunity a sealed environment. Can be easily installed and Improved power management for longer battery life ** mounted for long-term use. (12+ years on AA batteries) Encrypt-RF Security (Diffie-Hellman Key Exchange Accurate to 1 C ( 1.8F) + AES-128 CBC for sensor data messages) Increased accuracy by user calibration All ALTA sensors now have up to 3200 readings: to 0.25 C ( 0.45 F) - 10-minute heartbeats = 22 days Probe temperature range of -40C to +150C - 2-hour heartbeats = 266 days (-40F to +302F) Over-the-air updates (future proof) 8 ft UL listed plenum cable Free iMonnit basic online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email Principle of Operation Actual range may vary depending on environment. * The ALTA Wireless Duct Temperature Sensor outputs Battery life is determined by sensor reporting ** the ambient temperature in degrees Fahrenheit. It is frequency and other variables. Other power options programmed to sleep for a user-given time interval are also available. (heartbeat) and then wakeup, send power to the temperature probe, wait for temperature to stabilize, then transmit the temperature data to the gateway. Wireless Range Comparison Wireless Range Comparison To stay within the abilities of the processor, the temperature is computed off a data table provided by the manufacturer. Monnit ALTA Industry leading 25 month NIST certified product included on leaded temperature sensors.
