MiCS-2710

MiCS-2710 NO2 Sensor This datasheet describes the use of the MiCS-2710. The package and the mode of operation illustrated in this document target the detection of nitrogen dioxide (NO2). FEATURES Low heater current Wide detection range High sensitivity Fast thermal response Miniature dimensions High resistance to shocks and vibrations IMPORTANT PRECAUTIONS Read the following instructions carefully before using the MiCS-2710 sensor described in this document to avoid erroneous readings and to prevent the device from permanent damage. The sensor must not be wave soldered without protection, or exposed to high concentrations of organic solvents, ammonia, or silicone vapours, to avoid poisoning the sensitive layer. Heating powers above the maximum rating of 120 mW can destroy the sensor due to overheating. This sensor is to be placed in a filtered package that protects it against any water or dust projection. For any additional questions, email enquiries@e2v.com or telephone +44 (0)1245 493493. OPERATING MODE The recommended mode of operation is a constant power mode. A heater power of PH = 43 mW is applied. This causes the temperature of the sensing resistor (RS) to reach about 220 °C. Detection of the pollution gases is achieved by measuring the sensing resistor RS during operation. SENSOR RESPONSE The sensor response to NO2 in air is represented in Fig. 1. 1000 100 10 0.1 1 NO2 [ppm] 10 The sensor resistance RS is normalised to the resistance under a...
