MQ-9 Carbon Monoxide, Methane and LPG Gas Sensor Module

175.00 inc. GST
  • Input voltage: DC 5V
  • Power: 150mA
  • DO output: TTL digital 0 and 1 (0.1 and 5V)
  • AO output: 0.1-0.3V (relatively clean), the highest concentration voltage is about 4V.
  • Suitable for home or factory gas leakage monitoring devices.
  • Have better sensitivity to Carbon Monoxide, Methane and LPG Gas.
  • High quality dual-panel design, with power indicator and TTL signal output instructions.
