MGS1100

The Motorola MGS1100 carbon monoxiode(CO)sensor features a sensitive,thin film metal-oxide layer over an embedded micro-heater.The heater is used to raise the temperature of the film to enchance its sensitivity to CO.This structure of MGS1100 is supported by a micromachined silicon disphragm for reduced power consumption.

Features of the MGS1100 are:(1)sensitivity range: 15 to over 1000 pm CO; (2)low humdity dependence in recommended operation mode stable long-term operation; (3)thin film metal-oxide on micromachined silicon diaphragm; (4)active charcoal filter for enhanced selectivity; (5)durable nylon exterior shell with steel mesh; (6)small size.

The absolute maximum ratings of the MGS1100 can be summarized as:(1): maximum heater supply voltage(pins 1 and 3)(VH) is 5.0 V; (2): maximum sensor circuit voltage(pins 2 and 4)(VS) is 5.0 V; (3): maximum heater power dissipation(PH) is 230 mW; (4): maximum sensor power dissipation(PS) is 1.0 mW; (5): maximum heater voltage ramp(tVH) is 0.5 V/ms; (6): operating ambient temperature is 0 to 50; (7): storage temperature range(Tstg) is -40 to +70.
