Abstract:
A clock and ambient air condition sensing apparatus, comprising:a housing having opposed top and bottom walls with a continuous side wall extending between said top and bottom walls and defining a chamber, said side wall defining a plurality of apertures for passage of ambient air therethrough and into said chamber; an alarm positioned in said chamber; an ambient air condition sensor positioned in said chamber for providing a data signal corresponding to a preselected parameter of a condition of ambient air; a logic circuit positioned in said chamber and capable of evaluating input data supplied thereto, said circuit being electrically connected to said ambient air condition sensor and including means for generating an output signal to energize said alarm if upon evaluation said data signal is indicative of a predetermined ambient air condition; a first battery electrically connected to said circuit, said circuit including means for directing current from said first battery to said ambient air condition sensor; a display means coupled to said bottom wall of said housing and depending therefrom for indicating a relative time; a second battery electrically connected to said circuit, said circuit including means for directing current from said second battery to said display means; and means for providing battery strength data to said circuit for evaluation indicative of operation of said first and second batteries, said circuit including means for directing current from said second battery to said ambient air condition sensor if upon evaluation said battery strength data is indicative of an inoperability of said first battery.
