The device incorporates a battery input and maintains accurate timekeeping when the main power to the device is interrupted. The DS3231 is a low-cost, extremely accurate I☬ real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. All the components can be easily purchased from Amazon. Arduino DS3231 Real Time Clock with Alarm & Temperatureįollowing are the components required for making this project. Arduino DS3231 Real Time Clock (RTC) with Temperature MonitorĢ. You can refer to our earlier post if you wanna use DS3231 with Arduino Boards:ġ. The DS3231 RTC has a built-in alarm functions as well as temperature sensor with a resolution of 0.25 and an accuracy of ☓☌ which make this project more easier. We will use DS3231 Real Time Clock (RTC) module to keep track of the correct time & date & display it on OLED Display using STM32F103C8 as our microcontroller.
In this project we will learn how to interface the RTC Module DS3231 with STM32 (STM32F103C8 Board) and 0.96″ I2C OLED Display. Circuit: STM32 & DS3231 Based Real Time Clock.
