by The Leading Enterprise Internet of Things Solution Wireless Temperature Sensors General Description Features of Monnit ALTA Sensors The ALTA Wireless Temperature Sensor uses a type Wireless range of 1,200+ feet through 12+ walls * NTC thermistor to measure temperature. Frequency-Hopping Spread Spectrum (FHSS) Improved interference immunity Accurate to 1 C ( 1.8 F) Improved power management for longer battery life ** Increased accuracy by user calibration (12+ years on AA batteries) to 0.25 C ( 0.45 F) Encrypt-RF Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages) Datalogs 2000 to 4000 readings if gateway connection is lost (non-volatile flash, persists through the power Principle of Operation cycle): - 10-minute heartbeats = ~ 22 days The ALTA Wireless Temperature Sensor measures the - 2-hour heartbeats = ~ 266 days ambient thermal conditions of your environment. These Over-the-air updates (future proof) sensors accurately monitor temperature changes in Free iMonnit basic online wireless sensor monitoring your physical location. Settings including notifications, and notification system to configure sensors, view alerts, reports, and maps are customizable in the online data and set alerts via SMS text and email interface of iMonnit. The temperature sensor is built to be out of the box and running in minutes. Actual range may vary depending on environment. * Industry leading 25 month NIST certified product ** Battery life is determined by sensor reporting included on leaded temperature sensors. frequency and other variables. Other power options are also available. The ALTA Temperature Sensor is not meant Wireless Range Comparison for wet, damp, high humidity environments. This sensor should only be operated in dry, low Wireless Range Comparison humidity environments. Should you need a temperature Monnit ALTA sensor that operates at extreme temperatures and can withstand getting wet or condensed on, please consider our Thermocouple Sensors.
