Rain Alarm Circuit Snow, Water and Rain Detector Project Rain Alarm Circuit. We hope that now you may have a good knowledge of rain sensor and its working. The second main component of this circuit is 555 Timer IC. This 8 pin 555 Timer IC generally operates in three modes namely A sable mode, Mono Stable mode and Bi Stable mode. In rain alarm circuit, the main reason behind using 555 Timer IC is to trigger the buzzer for producing oscillating sound. Simple Rain Alarm Circuit Diagram Circuits99 Rain Alarm Circuit Diagram. The Simple Rain Alarm Circuit Diagram is used to give an alert when it’s going to rain. This circuit is used in homes to guard their washed clothes and other things that are vulnerable to rain when they stay in the home most of the time for their work. The required components to build this circuit are probes. 10K and 330K resistors, BC548 and BC 558 transistors, 3V battery, 01mf capacitor, and speaker. Rain alarm circuit – Circuit Wiring Diagrams The rain detector circuit is based on two transistors (Q1 & Q2) and a NE555IC (IC1). The two transistors are wired as a switch which goes on when the base of Q1 is shorted to the positive of the supply by the rainwater falling on the sensor. When the transistors are ON power supply is available to the IC1 which is wired as an astable multivibrator. The output of IC1 drives the speaker to produce an alarm. Rain Alarm Project and Circuit Diagram using 555 Timer IC It is a very simple rain alarm circuit which is designed using mainly a transistor, water sensor and a 555 timer IC. Whenever there is a rain, rain drops falls on the rain sensor, and as you can see in the diagram of rain sensor, water on rain sensor would short the Point A and B. Rain Alarm Circuit Science project with rain detector ... Description. Here is a simple rain alarm circuit that produces an audible alarm when ever rain falls. The rain detector circuit is based on two transistors (Q1 & Q2) and a NE555IC (IC1). How to make a Rain Alarm Circuit at Home In this project, we have designed a simple Rain Alarm Circuit, which, upon detecting rain, will activate a buzzer. Based on the buzzer, we can take necessary actions. Based on the buzzer, we can ... SIMPLE RAIN DETECTOR AND ALARM CIRCUIT | MyCircuits9 RAIN ALARM CIRCUIT EXPLANATION The Transistors Q1 and Q2 forms Darlington Pair, when a high Impedence (water) is given to its input it will trigger and generate an output voltage This voltage will trigger the alarming section containing UM66 IC and the Transistor Q3 will drive the Loudspeaker. Rain Sensor Alarm | Circuit Diagram A rain sensor alarm circuit can be a very beneficial device for alerting when rainfall happens. The rain detector circuit shown here is very simple using only three components but is very sensitive to detect rain or moisture.
