Features, Applications

The is a robust MEMS sensor for nitrogen dioxide and leakage detection.

Smallest footprint for compact designs x 1.55 mm) Robust MEMS sensor for harsh environments High-volume manufacturing for low-cost applications Short lead-times

Characteristic OX sensor Sensing resistance in air (see note 1) Symbol R0 Typ Min 0.8 Max 20 Unit k

Notes: 1. Sensing resistance in air R0 is measured under controlled ambient conditions, i.e. synthetic air 23 5C and 10% RH. Sampling test. 2. Sensitivity factor is defined at 0.25 ppm NO2, divided RS in air. Test conditions are 5C and 5% RH. Indicative values only. Sampling test.

IMPORTANT PRECAUTIONS: Read the following instructions carefully before using the MiCS-2714 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 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.

MiCS-2714 with recommended supply circuit (top view)
Power circuit and measurement circuit is 131. This resistor is necessary to obtain the right

temperature on the heater while using a single 5 V power supply. The resulting voltages is typically 1.7 V.

MiCS-2714 with measurement circuit (top view) The voltage measured on the load resistor is directly linked to the resistance of the sensor. RLOAD must W at the lowest in order not to damage the sensitive layer.
