The utility model discloses a rainfall monitoring device based on sound signals. The rainfall monitoring device comprises a single-chip microcomputer, a microphone preamplifier, a wind speed and direction sensor, a serial port communication module and a GSM module, wherein the microphone preamplifier and the wind speed and direction sensor are used for collecting the sound signals. The device mainly utilizes a plurality of microphone preamplifiers and sensors to collect rainfall sound and wind speed and direction, adopts a multi-ADC timer interruption sampling method to amplify and filter the collected sound in sequence, converts analog signals into digital signals, and sends the digital signals to the computer. Signals are transmitted to the upper computer through the serial port communication module and the GSM module, and de-noising processing and BP neural network processing are carried out, so that real-time rainfall monitoring is realized, and the accuracy of environmental rainfall monitoring is improve
