Hello again, my previous IoT project with using an ESP32 Dev board and JSN-SR04T sensor. was a succes. This i'm planing to upgrade the Sonar using fish finder transducer like this one (https://www.tokopedia.com/justinjonathan/sonar-sensor-pencari-ikanportable-100m-fish-findergps-lacak-ikan?trkid=f=Ca0000L000P0W0S0Sh,Co0Po0Fr0Cb0_src=search_page=1_ob=1000_q=sonar+sensor_bmexp=0_po=3_catid=1458_bmexp=0&whid=0)
Is it possible to just use the transducer, rewire the cable to interface with the ESP32 Dev Board(or arduino UNO), and add an external battery to drive the transducer ?
Thanks in advance
