Details
This project aims to measure temperature using an NTC (Negative Temperature Coefficient) sensor (also known as a thermistor) every 9 seconds and record the data along with timestamps onto a microSD card. Here’s how it works: The NTC sensor detects temperature variations, and the real-time clock (RTC) module provides precise timestamps. The Arduino reads temperature data from the sensor and saves it, along with the current time, onto the microSD card. The project utilizes I2C for communication with the RTC module and SPI for the microSD card. NTC temperature sensors find applications in HVAC systems, home appliances, and wireless charging
