PRODUCT INTRODUCTION

MQ-5 MQ5 MQ-3 MQ3 sensor module  alcohol ethanol gas sensitive detection alarm  for arduino DIY KIT

1   has  a  signal  output  instructions  .

2    dual  signal  output  (  T  TL level  output  and  analog  output  )

3   effective  signal  ,  TTL  output  for  low  level  .  (  When  output  low  level  lights  light  up  ,  can  be  directly  connected  single  -  chip  )

4   0~5V  analog  output  voltage  ,  higher  the  concentration  ,  the  higher  voltage  .

5    ethanol  vapor  has  a  high  sensitivity  and  good  selectivity  . 

6   with  long  periods  of  stability  and  service  life

 7   rapid  response  recovery  characteristics

 

Five  application  :

 

For  motor  vehicle  drivers  and  other  non  -  drinking  workers  on-site  inspection  ,  also  used   in  other  places  at the  ethanol  vapour  detection


VCC: positive power supply (5V)

GND: power supply is negative

DO: TTL switching signal output

AO: analog signal output
