MiCS-5914 Data Sheet 1108 rev 4 The MiCS-5914 is a compact MOS sensor. The MiCS-5914 is a robust MEMS sensor for ammonia detection suitable also for gas leak detection and indoor and outdoor air quality monitoring. Features Smallest footprint for compact designs (5 x 7 x 1.55 mm) 10.0 Robust MEMS sensor for harsh environments High-volume manufacturing for low-cost applications 1.0 Propane Short lead-times Hydrogen 0.1 Iso-butane Ethanol Ammonia 0.0 Detectable gases 1 10 100 1000 10000 100000 Concentration ppm Ammonia NH 1 500ppm 3 Ethanol C H OH 10 500ppm 2 5 Hydrogen H 1 1000ppm 2 Continuous power ON, 25C, 50% RH Propane C H >1000ppm 3 8 Iso-butane C H >1000ppm 4 10 For more information please contact: info.em sgxsensortech.com SGX Sensortech, Courtils 1 CH-2035 Corcelles-Cormondrche Switzerland www.sgxsensortech.com Page 1 of 5 Rs/R0MiCS-5914 Data Sheet 1108 rev 4 Performance sensor Characteristic Symbol Typ Min Max Unit RED sensor Sensing resistance in air (see note 1) R - 10 1500 k 0 Typical NH3 detection range FS 1 300 ppm Sensitivity factor (see note 2) S - 1.5 15 - R Notes: 1. Sensing resistance in air R is measured under controlled ambient conditions, i.e. synthetic air at 23 0 5C and 50 10% RH. Sampling test. 2. Sensitivity factor is defined as R in air divided by R at 1 ppm of NH . Test conditions are 23 5C s s 3 and 50 10% RH. Indicative values only. Sampling test. IMPORTANT PRECAUTIONS: Read the following instructions carefully before using the MiCS-5914 described here to avoid erroneous readings and to prevent the device from permanent damage. The sensor must be reflow soldered in a neutral atmosphere, without soldering flux vapours. The sensor must not be exposed to high concentrations of organic solvents, silicone vapours or cigarette-smoke in order to avoid poisoning the sensitive layer. Heater voltage above the specified maximum rating will destroy the sensor due to overheating. This sensor is to be placed in a filtered package that protects it against water and dust projections. SGX sensortech strongly recommends using ESD protection equipment to handle the sensor. Page 2 of 5
