DYNAMIC ALARM SENSITIVITY ADJUSTMENT AND AUTO-CALIBRATING SMOKE DETECTION FOR REDUCED RESOURCE MICROPROCESSORS

摘要

A hazardous condition detection system with a sensor package and employing a reduced resource microprocessor capable of dynamic alarm sensitivity adjustment having volatile and non-volatile memory which receives periodic raw sensor readings from the sensor package and preprocesses each received periodic raw sensor reading by employing at least three distinctive filtering constants which are compared to alarm thresholds stored in memory to generate an alarm condition signal when ionization levels in the ambient environment exceed the stored thresholds.
