Rain Detector Pdf

The rain sensor may be built any number of ways and is simply two conductors that are bridged by the rain water. Once the glue has dried, use scissors to carefully trim the plastic flush with the penny. The rain drops bridge the gap causing conduction which is sensed by the circuit shown in fig.

How to make the rain alarm and using by component for circuit diagram. It consists of a penny and nickel sandwiched together with a plastic insulator in the middle. Cut the nail short with a pair of old cutters or the cutter on a pair of pliers not your best electronic wire cutters since the core of the nail is steel. Neither the construction or the components are critical but I do recommend a connector for the sensor to make it easy to work on the box.

For connection to a computer, I recommend replacing the beeper with an optoisolator to protect the computer. Help friends, I want to know why it must be this resistor values to be used.

Rain Alarm Project

Two conductors of bare copper wire are woven through the holes so that the conductors are near each other but do not come into contact. Can you tell me the substitute method of making this project. You must make the joint very quickly or the battery will be damaged!

We can also use copper wire for rain sensor but copper generally reacts to oxygen to form oxide, so it needs to be cleaned on regular basis. The circuit diagram from the Rain Alarm Project is shown in the below image. Wrap the nail with tape to mask it and spray the exposed face of the plastic washer with glue.

But if you start to pay attention, you will be surprised how often you miss the start of a rain storm. With this simple rain detector, the first few drops of rain will sound the alarm allowing you a few precious seconds to roll up windows and bring in possessions. They are useful devices and play an important role in various industries such as automobile, irrigation, new york city metro map pdf and wireless communication. Position the penny right in the center of the nickel and let the glue dry. What do you think is the concept of this project?

What should be the Voltage that we need to pass through the wires? Directly soldering to a battery is a delicate process and I recommend a battery holder for the less experienced solderer. Please reply me fast as possible. Solder one conductors of a length of phone wire to the nail and the other to the nickel as shown in the photo.

The copper-plated nails are available at most hardware stores. Sir, the circuit is working perfectly but the buzzer wont stop ringing. Notice the holes each conductor uses are staggered so the loops underneath miss each other.

Hello sir we are working on this project. Sir please send me the hr humidity sensor background. All projects on the Website are properly tested and working. Make sure one end is perfectly flat and straight. Leave a Reply Cancel reply Your email address will not be published.

Here is the simple and reliable circuit of rain water detector which can be constructed at low cost. Solder the head of the nail to the penny with a complete fillet to seal out the rain.

Bakelite or Mica board should be made completely flat and aluminium wire should be pasted on the flat board as shown in the figure below. Your email address will not be published.

How can i connect a speaker instead of buzzer? Once that has cured, turn the assembly over and pour a tablespoon or two of epoxy into the tube to get a really good seal. Coat that end of the pipe with epoxy and feed the wire through to glue the nickel in position. Where can I find a good rain sensor? Can you please tell me the connections, if possible.

Plz check the connection of the transistor. Also check your circuit again. Saving water and proper usage of water is very important. Lead the wire inside the house to the electronics, leaving a hanging loop near the entry point to prevent water from following the wire inside, add a connector and that's it.

The Gap between the wires should be around mm. The Rain Water Sensor used in this project is shown in the image below. The block diagram of the Rain Alarm Project is shown in the following image.

And I am also curious that is it possible to implement a diode into this circuit? The simple serial port interface might be an interesting starting point. The goal is to form an insulating washer the exact size of the penny.
