Overview
The 1-5V output noise measurement sensor consists of a voltage module JHM-MV05 and a noise sensor JHM-NS02, with a voltage signal output of 0-5 (voltage output can be selected from 0-3v3 0-5v 0-10v), for real-time monitoring of noise.
Product Details
1-5V output noise measurement sensorIntroduction:
Product model: JHM-NS02
Specification: 80mmX25mm
Measurement error:+/-1.5dB (2Khz80dB point correction)
Conversion accuracy: 0.1dB
Output mode: Extended 0-5V (optional 0-3v3 0-10V)
Frequency weighting characteristic: A-weighting characteristic
Microphone manufacturer: Toshiba capacitor (windproof outer cover)
A-weighted dynamic measurement range: 30dB to 120dB (automatic shifting)
Frequency response: 35 Hz to 20KHz
Dynamic characteristics: FAST
Working and storage temperature: -10---60 ℃
Working and storage humidity: 10-90RH%
Power standard: DC9V-DC12V (ripple<0.5%) current 30mA
Manufacturer: Beijing Jinghaiming Electronic Technology Research Institute
1-5V output noise measurement sensormodule
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折算公式： db = (vo-2)*12.5 + 30
