TDS water quality sensor con ESP32

Alimentazione 3.3-5 V Bus ANALOG Misura TDS (sali disciolti)

Pin e collegamento all’ESP32

Pin	Ruolo	Pin ESP32	Note
A	Uscita analogica	D34	0 to 2.3 V, safe for the ESP32. To an ADC1 pin (GPIO 32 to 39)
VCC	Alimentazione	3V3	Marked + on the board
GND	Massa	GND	Marked - on the board

Collegamento consigliato per l’ESP32 DevKit a 30 pin, evitando i pin della flash, di sola lettura e di strapping. BoardPilot lo controlla mentre colleghi.

Codice di partenza (Arduino)

void setup() { Serial.begin(115200); }

void loop() {
  int mv = analogReadMilliVolts(34);  // A on GPIO 34
  Serial.println(mv);
  delay(200);
}
