Ultrasonic Presence Sensor

Presence detection is stable even for targets such as mesh trays or springs.

Ultrasonic presence sensor.

The optex ovs 01gt 18 range microwave ultrasonic vehicle presence sensor detects the presence of moving or stationary vehicles and has the ability to ignore human movement. Elmos has more than 20 years experience in developing and producing ultrasonic ics. Ultrasonic level sensors measure the distance to the target by measuring the time between the emission and reception. Ultrasonic sensors measure the distance to the target by measuring the time between the emission and reception.

Plastic or stainless steel housing with threaded barrel or flat pak sensing head. Ultrasonic sensors support a wide range of needs from kiosk based applications to human proximity sensing and. Every ic generation has become better and better. The sensor determines the distance to a target by measuring time.

Our ultrasonic sensors offer the ability to detect people over a wide range of distances with a high read rate and excellent reading to reading stability. Our sensors are available in several sensing ranges and styles with either an analog or discrete output depending on the model. They emit ultrasonic waves and analyze the time it takes to return to determine. This is one class of proximity sensor that s useful in human presence detection.

The designer series sensors automatically control lighting and other electrical loads based on the presence or absence of people. This full line of stylishly designed ultrasonic occupancy sensors can be used either individually or in combination to provide lighting and hvac control throughout a building. Our ultrasonic sensors like many others use a single transducer to send a pulse and to receive the echo. Maxbotix ultrasonic sensors solve the common problem of sensing human presence.

For automotive or industrial applications. Unlike other vehicle sensors it installs above the ground eliminating the need for cutting concrete and the installation of a ground loop. An optical sensor has a transmitter and receiver whereas an ultrasonic sensor uses a single ultrasonic element for both emission and reception. Presence detection is stable even for targets such as mesh trays or springs.

Ultrasonic sensors use sound waves rather than light making them ideal for stable detection of uneven surfaces liquids clear objects and objects in dirty environments. Ultrasonic sensors work by sending out a sound wave at a frequency above the range of human hearing. How ultrasonic sensors work. The sensor head emits an ultrasonic wave and receives the wave reflected back from the target.

The transducer of the sensor acts as a microphone to receive and send the ultrasonic sound.
