RGB LED is the abbreviation of ‘’Red Green Blue Light Emitting Diode’’. RGB LED is the most amazing type of LED which has the ability to create millions of different shades of light colors using red, green, and blue colors.
The soil moisture sensor is the most amazing sensor used to measure the quantity of water present in the soil and defines the moisture level of the soil as the output. Because of its amazing operating principle, this sensor is used in applications such as automatic irrigation systems, agriculture research applications, landscape irrigation, indoor planting system, and lawns. I have also made an advanced level project "Smart Plant Watering System" using a soil moisture sensor.
