Level Transducer Circuit Implemented by Ultrasonic Sensor and Controlled with Arduino Nano for its Application in a Water Tank of a Fire System

This article aims to describe the design of a circuit level transducer implemented by means an ultrasonic sensor and controlled Arduino Nano, applied water tank firefighting system. Initially, integration Siemens 1212C programmable logic controller is described, in connection between sensor, interfaces that allow generate monitoring, control data recording, conditioned PWM pulse width modulated signal Nano. When developing research performing analysis linear regression model, it established behavior variable with respect time, generates voltage response range 0 10 volts; expressing terms correlational relationship factor R2 equal 0.997, thus establishing designed does not show susceptibility noise or disturbances start-up
