The rain alert circuit combines both a sound circuit and a rain detection sensor into a single system. Its main principle of operation is that when raindrops hit the sensor, the sound circuit will trigger and produce sound through a speaker. Most commercially available circuits typically alert using a beep or buzzer sound. However, this unique circuit differs from others by emitting frog and toad sounds instead, mimicking the natural environment of a forest. This makes it ideal for educational purposes or for use in urban areas that desire natural sounds when it rains.
