This ultrasonic sensor returns liquid or solid levels via acoustic waves. It is ideally suited for monitoring fuel oil tank levels or sending via LoRa and SigFox network, the filling rate for clothes container and refuse bins.

This device is powered by an interchangeable 2400mAh Lithium primary battery giving several years of autonomy for a standard use case of one measurment per hour (a life time calculator is given on the NEMEUS wiki page to evaluate autonomy for a specific use case).

As an option, this device can be powered by an external power supply from 5V to 30V (useful in LoRa WAN Class C mode). This device can also be supplied with an external SMA connector if a harsh environment (such as a metal box) requires an output antenna.

Features:

• Dimension: 60 x 33 x 85mm (109mm including fixing brackets, 96mm spacing between bracket)
• IP65 classified, Solid ABS & PC material
• Default configuration allows target detection until 3 meters
• Detection of objects from 0cm to 20cm range as 20cm or closer
• The acoustic detection pattern has an angle of 7°. The geometry of the detection pattern depends mainly on the size, orientation, and acoustic properties of the target, but also on the atmospheric pressure, temperature and humidity
