There are three major types of carbon monoxide senors.

  • Biomimetic: A gel changes color when it absorbs carbon monoxide.
  • Metal oxide semiconductor: When the chip's circuit detects carbon monoxide, electrical resistance decreases, and this triggers an alarm.
  • Electrochemical: Electrodes immersed in a chemical solution sense changes in current when they come into contact with carbon monoxide, and this change triggers the alarm.
