IIJHM-MV05 module:

Working voltage: DC 12V regulated power supply, working current 100mA (ripple<0.5%),

Output load:<3mA

Output algorithm: dB=(V0)–1) 100/4+30. For example, 3.8v corresponds to a noise value of (3.8-1) * 100/4+30=100dB.

0-3.3v 折算公式： db = (vo-0.667)*37.98 +30

------------------------------------------------------------

0-10V conversion formula:db = (vo-2)*12.5 + 30
