Abstract / Excerpt:

This system is an approach for a low-cost, accessible, mobile and easy to install wireless weather station and alert messaging system, using Android and Arduino. It monitors the condition of the physical environment such as pressure, humidity, temperature, light levels, wind speed, wind direction, and rainfall, all in real time mode.

It uses an Arduino microcontroller with the integration of a USB weather board and weather meters. The Arduino Weather Board continuously sends data to the Android device through Bluetooth. The received data is stored in a database for an application that uses the Amarino API. For remote monitoring, there are two ways for a user to get weather data. First, a remote phone requests for the condition of the physical environment by sending an SMS to the Android phone. The Android phone sends the gathered data to the remote phone via SMS. Second, the Android alerts the user about any abnormal conditions like temperature rise, etc. by automatically sending an SMS to the remote phone.

T-test is used to compare the temperature ans humidity collected by the system with data collected from a reference weather stations. The results indicate that the Mean Absolute Error (MAE) of the temperature is 2.18°C and the MAE of the humidity is 2.66%. With these, results for the comparison of the two weather data have shown minimal error. Its weather data have shown minimal error. Its weather real-time monitoring is still within limits to the reference weather station. Also, a comparison of the cost of the some existing systems has been carried out and it shows that that the proposed system is a better choice in terms of cost.
