Cricket stadiums are really places. Cricket is a popular game that people all around the world like to play and watch. Sometimes it rains and this causes problems for cricket stadiums. Matches get. Postponed because of the rain. To solve this problem, we have an idea for a system that can detect rain and send out an alert. This system will have a roof that can automatically open and close. The roof will cover the cricket stadium. When it starts raining a sensor will detect the rain. Send a signal to the Arduino UNO and GSM. Then the LED light will turn on a buzzer will make a sound. The roof will close by itself using a special motor. At the time a message will be sent to a mobile phone to let people know that it is raining. When the rain stops the roof will automatically open again. This way cricket stadiums will not have to cancel matches because of the rain. Cricket stadiums, with this system, will be able to host matches without any problems caused by rain.
