3. 🔌 Connections

Module only

Module	Controller
GND	ground
VCC	3.3 - 5 volt power supply
SCL	SCL
SDA	SDA
PROBE_1	input probe wire
PROBE_2	reference probe wire

Carrier Board

Carrier Board	Controller
GND	ground
VIN	3.3 - 5 volt power supply
SCL	SCL
SDA	SDA
1W	optional 1-wire device signal line
EN	optional EN wire, drive HIGH to disable both power modules

Carrier 1W Header	1-Wire Sensor

Probe connection is made with the SMA connector, using a SMA-BNC Bulkhead or similar.

4. 🔢 Code

Below is the Basic example. It can be found in File > Examples > Microfire_Mod-pH > Basic in the Arduino IDE.

#include <Microfire_Mod-pH.h>
Microfire::Mod_pH::i2c ph;

void setup() {
	Serial.begin(9600);
	Wire.begin();
	ph.begin();
}

void loop() {
	ph.measurepH(ph.tempC);
	Serial.println((String) ph.pH + " pH");
	delay(1000);
}
