Abstract:
1. A microprocessor controlled hazardous condition detection system comprising: a housing containing a sensor package, said sensor package containing sensors said sensors being exposed to an ambient environment and taking periodic readings of predetermined environmental conditions; an alarm means associated with said sensor package and disposed in said housing; a microprocessor electronically coupled to said alarm means and sensor package, said microprocessor having volatile and non-volatile memory, said non-volatile memory having an alarm differential value and a clean air default value stored therein; wherein a default alarm threshold is determined by adding said differential value to said clean air default value; wherein upon system power-up, said default alarm threshold is loaded into said volatile memory; said microprocessor receives periodic readings of predetermined environmental conditions from said sensor package stores said periodic readings in said volatile memory and generates at least a set of a first and a second conditioned sensor readings CEV wherein upon detection of an ambient environmental condition outside of said alarm threshold stored in said volatile memory said microprocessor causes said alarm means to generate an alarm condition.
