A Rain Sensitive House Window Closes Automatically When Raining House windows are sometimes opened when it rains and no body around to close them allowing rain going in side and damage the house. Information of the problem In normal sunny days, people always leave the house windows open for air circulation or allowing sun rays. In case if we forget the house windows opened or we leave it because we do not expect rain might be fall, rains will fall inside the house. In rainy countries, the amount of the rain is too much and it might destroy the whole house if we forget or if we leave it open for other purposes, Water damage irrespective of the source always causes devastating and the blow is really hard especially for the people whose houses are located in rainy countries. When the water flows inside the house, it begins the troubles time. The rain water runs through every personal belonging which cause a financial loss. Also, water can damage furniture, devices or other valuable things. We want to figure a device that will save this mistake. A lot of people do not think that when rains fall a damage will happen to their houses but when it happen they will say in repeatedly I wish I closed the window or I wish I installed some devices that can close the window automatically. Think again! Constraint and Criteria. Automatic windows closing system can operate with power volt 110/220, 50/60 Hz. It shall be in accordance with the international safety requirements. Its price should not be more than $1000. Heavy duty Sealed Good in shape Easy to install Silent in operating

The sensor's software (known as Clarify) runs on Windows operating systems ranging from Windows 98 to XP. The software installation went off without a hitch. I ordered my sensor with a 100 foot cable and mounted the sensor on the lower roof of my house (Fig 1.). The cable was hidden underneath the siding and snaked along the outside of the house until it found its way into the family room. This is where the observatory's weather computer resides. I could have gotten away with only 50ft of cable, so the excess was coiled up and placed behind the rack the holds the weather PC. The sensor was attached to the house using 2 right angle brackets purchased at the local hardware store. The 2 brackets were screwed together and then screwed to the side of the house. Boltwood Cloud/Rain Sensor The sensor was then attached to the brackets via nylon wire ties. No installation brackets are included with the unit because there is no way for the manufacturer to know how the customer will mount the unit. Some may mount it to a house, or a observatory, or on a pole. The unit should be mounted with about a 10 degree tilt facing the direction of the prevailing winds. According to the manufacturer s instructions this serves two purposes; it helps prevent rain water from building up on the sensor plate, and it allows the sensor to see the clouds a bit earlier as they roll in.

The photo cell is connected to electrical starter which controls the motor that closes the window. Whenever there is clouds accumulation, the photo cell will activate and energize the motor. Motor will be stopped when the window is fully closed due to activation of a limit switch or infrareds sensor is activated due to sensing obstruction. The starter can be controlled by either photo cell or manual (bush button) _ Uninterrupted Power Supply (UPS) An uninterrupted power supply (UPS), also known as a battery back-up provides emergency power and, depending on the topology, provide line regulation as well to connected equipment by supplying power from a separate source when utility power is not available. This will work as a back-up for the Boltwood Cloud/Rain Sensor and the Photocell. Uninterrupted Power Supply Cost Item/Type Quantity Est. Cost $ 8051 1 69 Microcontroller Training Kit 1 62
