CO (Carbon Monoxide) Gas Sensor

SKU 605-00007 Categories ,


335 in stock

Product Description

Quantity limited to stock on hand.  The CO Gas Sensor is used in gas detection equipment for detecting Carbon Monoxide in home, automotive or industrial settings. When paired with our Gas Sensor Board (#27983) it provides a development system and test platform for CO gas sensor design.

Key Features:

  • Manufacturer Model MQ-7
  • High sensitivity to Carbon Monoxide (CO)
  • Stable and long life
  • Simple drive circuit

Application Ideas:

  • Safety Devices (harmful gas detection)
  • Environmental monitoring

Note: Please refer to the manufacturer datasheet for more informaton and circuit recommendations.

Note: This sensor, when paired with our Gas Sensor Board (#27983), replaces our CO Gas Sensor Module (#27931). Please note that on boards labeled 27983 pin 2 is active-high, and on boards labeled 27904, 27930, 27931, and 27932, pin 2 is active-low.
