Summary of SD Card Data Recorder
This project displays and logs four real-time measurements—AC voltage, ambient temperature, relative humidity, and 12-hour real time—onto an SD/microSD/MMC card while showing values live. It records sensor data for later review and provides a simple interface for monitoring electrical and environmental parameters.
Parts used in the SD Card Data Recorder:
- Microcontroller (e.g., Arduino or similar)
- SD/microSD/MMC card module or breakout
- Real time clock (RTC) module
- AC voltage sensing circuit
- Temperature sensor
- Humidity sensor
- Display (for 12-hour real time and readings)
- Power supply (appropriate for the microcontroller and sensors)
- Connecting wires and prototyping board or PCB
We always try to know the physical and electrical data like temperature, pressure, current, ac voltage etc. In this project, I’m going to display these data in the real time as well as I’ill record it to a memory card(SD/microSD/MMC card).
Here the project can display four different things; ac voltage, environment temperature, relative humidity and the real time in 12 hrs format.
