Real Time Clock (RTC) IIOT Module

Our RTC Input Module is an I2C enabled battery backed up RTC Module which is extremely accurate with an integrated temperature compensation oscillator and crystal.

The RTC Chip is a Maxim DS3231 RTC Chip are extremely robust in rugged environments.

Some main features of our RTC IIOT Module are:

  • Extremely Accurate
  • Battery Backup
  • Extended Temperature Range: -40°C to +85°C
  • Leap Year Compensation
  • Easy to get connected and configured

System Integration

Can be intergrated into any IIOT system that has a Master controller that supports I2C.

We give example code for Raspberry PI and Arduino hardware.

We also offer system integration and custom code as a service.
