Got it — I’ll turn this into a smart sump-pump water-level monitor around the ESP32-S3 N16R8, add a suitable water-level sensor interface, then add the needed power/programming/support parts rather than leaving just the MCU.
Implemented the smart sump-pump monitor schematic around the ESP32-S3-WROOM-1-N16R8 with a JSN-SR04T-2.0 waterproof ultrasonic water-level sensor, USB-C power/programming, 3.3V regulation, boot/reset buttons, status LED, and ESP32 strapping/support passives. ERC checks now show no open errors/warnings for the checked categories.
Open items:
The JSN-SR04T is powered from USB 5V; use a reliable isolated USB supply.
Add sensor-cable ESD/surge protection if the cable will be long or near pump wiring.
Suggested next steps:
Add protection for the sensor cable and USB input.
Move to PCB layout with ESP32 antenna keepout.
Review/update the firmware starter file for your exact sump dimensions.
