SENSOR INTERFACING SKILLS
Categories: CDOT_Certified Courses
About Course
Sensor interfacing is the skill of connecting and programming various sensors to microcontrollers like Arduino or ESP32 to collect real-world data such as temperature, light, motion, and humidity. It involves understanding sensor types (analog, digital, and communication-based like I2C, SPI, UART), interpreting datasheets, wiring circuits correctly, and writing code to read and process sensor data. This skill is essential for building embedded systems, IoT devices, and automation projects where real-time sensing and decision-making are required.
