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.
