Overview
MiCS-5525 CO Sensor This datasheet describes the use & performance of the MiCS-5525 sensor.
The package and the mode of operation illustrated in this document targets the detection of carbon monoxide (CO).
FEATURES • Low heater current • Wide detection range • Wide temperature range • High sensitivity • Miniature dimensions • High resistance to shocks and vibrations • Charcoal filter to improve selectivity to CO OPERATING MODE The recommended mode of operation is constant power.
The nominal power is PH = 76 mW.
The resulting temperature of the sensing layer is ~340 °C, in air at an ambient temperature of ~ 20 °C.
Detection of the pollution gases is achieved by measuring the sensing resistance of the sensor.
The resistance decreases in the presence of CO.
SENSOR CONFIGURATION The silicon gas sensor structure consists of an accurately micro machined diaphragm with an embedded heating resistor and the sensing layer on top.
The internal connections are shown below: 32 RH R...
