by LIGHT The Leading Enterprise Internet of Things Solution METER Wireless Light Meter General Description Features of Monnit ALTA Sensors The ALTA Wireless Light Meter measures the intensity Wireless range of 1,200+ feet through 12+ walls * of light from 083,000 LUX (luminescence/unit area), Frequency-Hopping Spread Spectrum (FHSS) and an optional detection reading of light/ no light. By Improved interference immunity default, the detection reading is triggered on LUX value Improved power management for longer battery life ** being above or below the configured minimum threshold (12+ years on AA batteries) value of the sensor. Encrypt-RF Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages) Datalogs 2000 to 4000 readings if gateway connection Measures the amount of light present is lost (non-volatile flash, persists through the power Can alert upon immediate detection of light or a cycle): change in light intensity - 10-minute heartbeats = ~ 22 days Highly sensitive photodiode - 2-hour heartbeats = ~ 266 days Over-the-air updates (future proof) Principle of Operation Free iMonnit basic online wireless sensor monitoring and notification system to configure sensors, view The ALTA Wireless Light Meter uses a highly sensitive data and set alerts via SMS text and email photo-diode to detect and measure the intensity of light Actual range may vary depending on environment. * around the device. The sensor is also capable of alerting Battery life is determined by sensor reporting ** upon detection of a change in lighting conditions. The frequency and other variables. Other power options sensor returns a value in LUX to the iMonnit Online Sensor are also available. Monitoring and Notification System. The data is stored in the online system and can be reviewed and exported as a data sheet or graph. Notifications can be set up through the Wireless Range Comparison online system to alert the user when light is present or not Wireless Range Comparison with the ability to only notify within time of day parameters.

Please take care when connecting a power device. * Power Options Example Applications The standard version of this sensor is powered by two replaceable 1.5 V Art gallery light metering AA sized batteries (included with purchase). Museum light metering Business light monitoring This sensor is also available with a line power option. The line powered Home light monitoring version of this sensor has a barrel power connector allowing it to be Many additional applications powered by a standard 3.03.6 V power supply. The line powered version also uses two standard 1.5 V AA batteries as backup for uninterrupted operation in the event of line power outage. Power options must be selected at time of purchase, as the internal hardware of the sensor must be changed to support the selected power requirements. PAGE 2
