AN ELECTRICALLY OPERATED WATER HEATERS EXHIBITING SMOOTH TRANSITION OF LED FROM ONE COLOR TO ANOTHER CORRESPONDING TO RISE IN WATER TEMPERATURE

摘要

The invention relates to an electrically operated water heaters exhibiting smooth transition of LED from one color to another corresponding to rise in water temperature, comprising a steel tank, an inlet pipe, an outlet pipe, a heating element, a thermal cutout, a pressure relief valve, an anode rod, an insulation structure, a power supply PCB a display PCB and an LED circuit formed of a temperature sensor, a microcontroller, a tri-color RGB LED strip, and a LED driver, wherein the temperature sensor senses the temperature of water inside the tank of the water heater and transmit the sensed data to the microcontroller in form of voltage, wherein the microcontroller senses the temperature and based on the sensed data changes the color of the RGB LED through the LED driver that provides a constant current to the LEDs.
