Monitoring the weather is important for everyone. Especially for the first ones, this is a very necessary thing. They can act as soon as they know the weather forecast. Current weather monitoring reports come from the news agency. They received weather information from a central system. Individual weather monitoring systems can accurately predict the weather for a specific area. Here we offer a solution as an Android-based weather monitoring system that uses Bluetooth. Nowadays, the demand for portable weather monitoring devices that can be relied upon for real-time warning and notification of changing environmental conditions is becoming more and more necessary. To meet these requirements, we have created an efficient, compact, and cost-effective weather station that provides us with valuable information about temperature and humidity through the highly reliable DHT11 sensor and HC-05 Bluetooth module. The DHT11 sensor ensures high temperature and humidity measurement accuracy, while the HC-05 Bluetooth module enables high data transfer speed, better range, and portability. Also, it monitors and controls the moisture level of the soil and sends the collected data to the farmers through an Android application using a Bluetooth controller.
