Simple Rain Detection Alarm Using Custom Rain Sensor

Hello freinds welcome back to "Techno-E-solution" In this article I'll show you how to make a "Simple Rain Detection Alarm Using Custom Rain Sensor." In this project we need to make a rain sensor Plate using Marker & Single side copper clad board. I also make a PCB for whole project file link also provided.

Working Principle :-

Here is basic principle are used to make this system. I used a BC 547 transistor & diy rain sensor plate when rain drops falls on plate the voltage through plate triggers transistor & buzzer starts to buzz.

LET'S MAKE PCB :-

Follow the following steps to make PCB using "Tonner transfer Technic"

• Cut PCB as per your choice.
• Draw using marker as shown in above image.
• take a 2-3 spoon of ferric chloride in water.
• Place PCB in the solution for 5-10 min.
• Clean the PCB with the help of PCB Cleaner.
• Drill the PCB using drill machine.
• Now your PCB Completed.
