DESCRIPTION

Returns a float with the temperature in Celsius of the internal thermometer on DS3231. Remember that if DS3231 is in a seal box, or other electronic components that raise the temperature near the DS3231, the temperature will be an approximation.

SYNTAX

RTC.tempC();

PARAMETERS

RETURNS

A float of the temperature in Celsius.

EXAMPLE

#include <SPI.h> #include <Wire.h> #include <InvIoT_RTC.h> #include <InvIoT_U1.h> InvIoT_U1 lcd(A0, A1); InvIoT_RTC rtc; void setup() { rtc.init(); } void loop() { lcd.clear(); lcd.print(rtc.tempC()); lcd.print('C'); delay(250); }
