Ultrasonic Presence Sensor

This is one class of proximity sensor that s useful in human presence detection.

Ultrasonic presence sensor.

Every ic generation has become better and better. For automotive or industrial applications. Maxbotix ultrasonic sensors solve the common problem of sensing human presence. Ultrasonic sensors for many applications such as monitoring the level of water in a tank ultrasonic technology lets a single device to do a job that would otherwise require multiple sensors.

Precision programmability to resolve object presence to within 0 6 mm. Our ultrasonic sensors like many others use a single transducer to send a pulse and to receive the echo. Elmos has more than 20 years experience in developing and producing ultrasonic ics. Plastic or stainless steel housing with threaded barrel or flat pak sensing head.

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. Presence detection is stable even for targets such as mesh trays or springs. 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. 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. The designer series sensors automatically control lighting and other electrical loads based on the presence or absence of people.

Ultrasonic sensors work by sending out a sound wave at a frequency above the range of human hearing. Unlike other vehicle sensors it installs above the ground eliminating the need for cutting concrete and the installation of a ground loop. 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 level sensors measure the distance to the target by measuring the time between the emission and reception.

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. With our broad know how we are able to deliver state of the art ic for the complete setup of a high class ultrasonic system e g. An optical sensor has a transmitter and receiver whereas an ultrasonic sensor uses a single ultrasonic element for both emission and reception. Ultrasonic sensors support a wide range of needs from kiosk based applications to human proximity sensing and.

Ultrasonic sensors measure the distance to the target by measuring the time between the emission and reception.
