How IoT Sensors are connected?
GPIO Separate line for each Sensor GPIO_C GPIO_B GPIO_A SoC Sensor B Sensor C Sensor A GPIO pins are especially good to use when programming simple sensors or actuators which only require single data line. For example: • LEDs, Relays, Buzzers, Buttons, Passive Infrared sensor (PIR) • Many more!
I2C Shared line for all Sensors SCL (clock) SDA (data) SoC Sensor A Sensor B Sensor C I2C pins are especially good to use when programming more complex sensors or actuators which require multiple data lines. For example: • Ultrasonic sensors, Stepper motors and servos, LCD screen, LED matrices • Many more!
Why IoTDK is good?
All different codes of Sensors on GPIO, I2C Requires implementing same code for every boards.
