    This document describes a temperature regulator for a solar water heater system. The system uses a rectifier to convert AC to DC, a 7805 voltage regulator to provide 5V power, and an AT89C52 microcontroller to control the system. It includes a DHT11 temperature sensor, LCD display, relay, DC pump, and crystal oscillator. The microcontroller monitors the water temperature using the sensor and controls the heater and pump using the relay to efficiently heat the water as needed for solar water heating.

    INPUT UNIT
    RECTIFIER:

    A rectifier is an electrical device that converts


    alternating current (AC), which periodically
    reverses direction, to direct current (DC), which
    flows in only one direction.

    AT89C52 Microcontroller:

    AT89C52 is an 8-bit microcontroller and belongs


    to Atmel’s 8051 family. AT89C52 has 8KB of Flash
    programmable and erasable read only memory
    (PEROM) and 256 bytes of RAM. AT89C52 has an
    endurance of 1000 Write/Erase cycles which means
    that it can be erased and programmed to a maximum
    of 1000 times.

    LCD:

    LCD (Liquid Crystal Display) is a type of flat


    panel display which uses liquid crystals in its primary
    form of operation. LEDs have a large and varying set
    of use cases for consumers and businesses, as they
    can be commonly found in smartphones, televisions,
    computer monitors and instrument panels.

    DHT 11 TEMPERATURE SENSOR:

    The DHT11 is a commonly used Temperature and


    humidity sensor that comes with a dedicated NTC to
    measure temperature and an 8-bit microcontroller to
    output the values of temperature and humidity as
    serial data.

    DC PUMP:

    DC powered pumps use direct current from motor,


    battery, or solar power to move fluid in a variety of
    ways. Motorized pumps typically operate on 6, 12,
    24, or 32 volts of DC power. Solar-powered DC
    pumps use photovoltaic (PV) panels with solar cells
    that produce direct current when exposed to sunlight.

    WORKING
    • The block diagram of solar water heater temperature control
    is shown in above figure.In this Block diagram we use
    supply voltage is 12 volt . Again we convert this 12 volt into
    5 volt by using power circuit.This 5 volt supply is given to
    the 8051 microcontroller.The programme stored in AT89C52
    microcontroller on that programme basis AT89C52
    microcontroller will work.Crystal oscillator is used for
    giving institution to the AT89C52 Microcontroller and
    execute microcontroller operation.Reset circuit is used to
    reset the AT89C52 microcontroller. The output of reset
    circuit is given to the AT89C52 microcontroller.

    • Relay is used is SPDT type, the output of microcontroller is
    given to the relay. The output of relay is given to heater. By
    using heater water is heated. LCD is used is 16*2 type. The
    temperature of water is showing on that Lcd display so we
    know that what is the temperature of water. DHT 11 sensor
    is temperature sensor by using this sensor we know the
    current temperature of water. The output of DHT11 sensor is
    given to 8051 microcontroller. The output of relay circuit is
    given to the DC pump. On the basis of temp & relay circuit
    DC pumps are operated.
