d-Piezo

YieldPoint’s d-Piezo digital piezometer integrates a MEMS transducer with a micro-controller to provide a robust digital solution for water pressure and depth monitoring. The output signal is directly in kPa(0.01kPa resolution) and degC (0.1oC resolution). The digital output string is tramsmitted as an RS485 signal, with 9600 baud rate(9600,9,n,1), and is ASCII encoded. Each instrument has a unique ID. RS485 signals tolerate wet conditions and the signals can be transmitted up to 1000m without amplification.

Data from an array of d-Piezos can be remotely monitored using YieldPoint’s Plug & Play data-loggers and telemetry solutions. Low cost wireless networking is available using d-Mesh 900MHz radios which have a standard LOS range of 500m. All solutions are eminently scalable.
