This work focuses on using rain Sensor, and it can beused in both everyday life and manufacturing. The ultimate goal of this project is to detect rain using a rain sensor. We used 555Ic, which works like a timer, sending a pulse as its signal, which is then read by the buzzer. https://www.theijire.com/archives/paper-details?paperid=295&papertitle=rain-detector-system-using-arduino-and-rain-sensor
