This Sound Level Meter is a stable, safe and reliable digital sound meter. The entire circuit is designed with the single chip processor as core, using the advanced circuit for sampling and signal processing.
The GSM Module/GPRS based on the Simcom Arduino Shield module. The module allows you to obtain SMS, MMS, GPRS and Audio via UART commands by sending AT commands (GSM commands 07.07, 07.05 and simCOM enhanced with COM commands). The module also has 12 GPIOs, 2 PWMs and an ADC from the SIM900 module (they are all 2V8 logic) present on board.
