LIGHT
METER
General Description
The ALTA Wireless Light Meter measures the intensity
of light from 0–83,000 LUX (luminescence/unit area),
and an optional detection reading of light/ no light. By
default, the detection reading is triggered on LUX value
being above or below the congured minimum threshold
value of the sensor.
• Measures the amount of light present
• Can alert upon immediate detection of light or a
change in light intensity
• Highly sensitive photodiode
Principle of Operation
The ALTA Wireless Light Meter uses a highly sensitive
photo-diode to detect and measure the intensity of light
around the device. The sensor is also capable of alerting
upon detection of a change in lighting conditions. The
sensor returns a value in “LUX” to the iMonnit Online Sensor
Monitoring and Notication System. The data is stored in
the online system and can be reviewed and exported as a
data sheet or graph. Notications can be set up through the
online system to alert the user when light is present or not
with the ability to only notify within time of day parameters.
Perfect for light sensitive applications like museum and art
gallery light monitoring

Power Options
The standard version of this sensor is powered by two replaceable 1.5 V
AA sized batteries (included with purchase).
This sensor is also available with a line power option. The line powered
version of this sensor has a barrel power connector allowing it to be
powered by a standard 3.0–3.6 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.
Example Applications
• Art gallery light metering
• Museum light metering
• Business light monitoring
• Home light monitoring
• Many additional applications

humidity and atmospheric pressure). Do not use these sensors under the following conditions as these factors can
deteriorate the product characteristics and cause failures and burnout.
• Corrosive gas or deoxidizing gas: chlorine gas, hydrogen sulde gas, ammonia gas, sulfuric acid gas, nitric oxides
gas, etc.
• Volatile or ammable gas
• Dusty conditions
• Low-pressure or high-pressure environments
• Wet or excessively humid locations
• Places with salt water, oils chemical liquids or organic solvents
• Where there are excessively strong vibrations
• Other places where similar hazardous conditions exist
Use these products within the specied temperature range. Higher temperature may cause deterioration of the
