TBSLS05/10 SDI-12 Ultrasonic Level Sensor

The TBSLS05 and TBSLS10 are ultrasonic level sensors with SDI-12 interface. The TBSLS05 is designed for a measurement range of 30cm to 5m and the TBSLS10 covers a range of 50cm to 10m. The TBSLS05S is a variant which is also capable of snow depth measurement. Stable, reliable range readings and excellent noise rejection make the sensor easy to use. The sensor automatically handles acoustic noise and provides a typical accuracy of 1% or better
