@kuriko i wanted the code to read in Fahrenheit . But also the issue is that it’s the reading the i2c connection but in UIFlow it does.

I'm using Arduino IDE 2.3.4 & having the issue with the unit reading the temperature data. If I use UIFLOW the sensor works perfect but whenever I try to get it to read thru IDE. It constantly just reads 2784 degree's. If I use the user demos . It picks up the i2c addy as the default 0x5A. Please help if possible, this is my code .

@felmue I apologize for sounding stupid & not doing my research. But could you possiblely show me where I need to put that in my code? I thought I put the formula in right. But I guess not .

i2c0 = I2C(0, scl=Pin(1), sda=Pin(2), freq=100000)
ncir2_0 = NCIR2Unit(i2c0, 0x5A)
ncir2_0.set_buzzer_control(0)
ncir2_0.set_rgb_led(0xcc33cc)
ncir2_0.set_emissivity_value(0.95)

def loop():
global DopeMete, Battery, Temperature, label5, label0, line0, label1, line2, label2, line1, label3, label4, i2c0, ncir2_0
M5.update()
label2.setText(str("%.2f"%float((((ncir2_0.get_temperature_value) * 9) / 5 + 32))))
label3.setText(str(ncir2_0.get_emissivity_value))
label4.setText(str(ncir2_0.get_button_status))
label5.setText(str(Power.getBatteryLevel()))

How would I go about changing the NCIR 2 unit to read from celsius to fahrenheit? Any help would be great
