Prevent costly downtime or waiting

Ultracompact with outsized benefits, Monnit’s Ultrasonic Ranging Sensor can prevent costly production downtime by tracking ingredient levels or detecting trucks waiting at loading docks.

Monnit’s Ultrasonic Sensors can be used in various applications to measure distances between the sensor and objects in its path. These sensors are impervious to target surface and colour and feature autocalibration algorithms which allow them to adapt to variable environmental conditions and compensate for temperature and humidity effects.

The Ultrasonic Sensor sends out a high-frequency sound pulse and then times how long it takes for the echo of the sound to reflect back. The sensor has two 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 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 defined condition is met. All sensor data is then stored for historical analysis.

WARNING: Tanks with liquid in them must be vented, otherwise condensation will accumulate on the lens and render readings inaccurate.

This sensor come standard with two replaceable AA batteries. The typical battery life is approximately 10 years.
