Wireless Ultrasonic Sensors
General Description
ALTA Ultrasonic Sensors can be used in a variety of
applications for measuring distances between the
sensor and objects in its path. ALTA ultrasonic sensors
are imperviousness to target surface and color, and
feature autocalibration algorithms which allow them
to adapt to variable environmental conditions and
compensate for temperature and humidity effects.
The ultrasonic sensors can also be calibrated through
the iMonnit software for greater accuracy in distance
measurements.
• Measures distance between the sensor and
objects in its path
• Measurement resolution of 1 centimeter
• Auto-calibration algorithms allow sensor to adapt
to variable environmental conditions
Principle of Operation
The Ultrasonic Sensor sends out a high-frequency
sound pulse and then times how long it takes for the
echo of the sound to reect back. The sensor has 2
openings on its front. One opening transmits ultrasonic
waves, (like a tiny speaker), the other receives them,
(like a tiny microphone). The ultrasonic sensor uses the
speed of sound to and time difference between sending
and receiving the sound pulse to determine the distance
to an object. It will take readings at set intervals and
report the data back to the iMonnit software portal
where the information is processed to display distance
and alert users if a dened condition is met. All sensor
data is then stored for historical analysis.

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 un-interupted 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.
