Kelvin Du investigated if adding a humidity sensor to an ionisation smoke alarm, and a photoelectric smoke alarm would stop cooking related false alarms. He found that an increase in humidity causes both ionisation and photoelectric smoke alarms to send fire warning signals. This indicates the benefits of modifying an alarm system to be sensitive to humidity to reduce false alarms.
