RAIN ALARM WITH AIR FLOW DETECTOR OUR MINI PROJECT: RAIN ALARM WITH AIR FLOW DETECTOR

BLOCK DIAGRAM OF THE PROJECT: REGULATED POWER SUPPLY +12V RAIN ALARM CICUIT AIR FLOW DETECOR CIRCUIT WATER SENSOR FILAMENT AS SENSOR SOUND PRODUCE LED GLOWS

RAIN ALARM A rain alarm is basically a device which gives an alarm when the sensor is in contact with water.

AIR FLOW DETECTOR The air flow detector circuit can give a visual indication of the rate of air flow. It can be also used to check whether there is air flow in a given space.

FOR OUR PROJECT…. AT FIRST WE MADE OUR DUAL POWER SUPPLY…

THE CIRCUIT DIAGRAM OF THE CIRCUIT:

THE COMPONENTS REQUIRED FOR THE POWER SUPPLY: Specification Quantity Transformer Voltage Regulator LED Diode Capacitor Resistor Bridge Rectifier 24v(p-p) 7812,7912 - 1N4007 2200µF/35V 10µF/25V 470Ω,1/2 W,5% 1 1 EACH 2 4

AIRFLOW DETECTOR CIRCUIT AFTER MAKING THE POWER SUPPLY WE GIVE THE REGULATED VOLTAGE SUPPLY OF +12V TO BOTH THE CIRCUIT.. +12V RAIN ALARM CIRCUIT AIRFLOW DETECTOR CIRCUIT

CIRCUIT DIAGRAM OF RAIN ALARM:

COMPONENTS REQUIRED FOR RAIN ALARM: 1.Power supply of 12 volts. 2.555 multi vibrator. 3. Resistors of 10K,56 K. 4.Capacitor of .01µF,1µF/15V. 5.Speaker of 8Ω/0.5W. 6. Water sensor.

CIRCUIT DIAGRAM OF AIR FLOW DETECTOR:

COMPONENTS REQUIRED FOR RAIN ALARM: 1.Power supply of (10-12) V. 2.100 Ohm,470 Ohm ,100 k,1k Resistor. 3. IC LM339, LM7805. 4. 47uF Electrolytic Capacitor. 5.LED. 6.Bulb Filament.

AFTER CONNECTING THE CIRCUIT,WE GET THE RESULTS AS.. RAIN ALARM CIRCUIT AIR FLOW DETECTOR CICUIT LED GLOWS WITH THE RATE OF AIR SOUND PRODUCE

APPLICATIONS: Rain Alarm can indicate the level of fluid in a container or simply the presence of fluid depending on the way the circuit is used. Air flow detector is use in the ship, to check the air flow in the sea..
