PT100 (3 wire) is connected to arduino uno as i believe i have them connected properly, i have checked other forums such as changing the capacitor to ferrite core, and probably changing up to 4 breakout boards to get the same result (getting crazy). I also tried switching 3,3v to 5v repeatedly and hence i would get various errors such as the following:
I am using the example from the adafruit example available from adafruit library with the instances:
Adafruit_MAX31865 thermo = Adafruit_MAX31865(10, 11, 12, 13);
// The value of the Rref resistor. Use 430.0 for PT100 and 4300.0 for PT1000
#define RREF 4300.0
// The 'nominal' 0-degrees-C resistance of the sensor
// 100.0 for PT100, 1000.0 for PT1000
#define RNOMINAL 1000.0
void setup() {
Serial.begin(115200);
Serial.println("Adafruit MAX31865 PT100 Sensor Test!");
thermo.begin(MAX31865_3WIRE); // set to 2WIRE or 4WIRE as necessary
}
and the error i always got:
RTD value: 0
Ratio = 0.00000000
Resistance = 0.00000000
Temperature = -242.02
Might not very an engineering way to troubleshoot things but i ordered the original adafruit MAX31865 breakout board instead. Here is my setup
