Product Description
Product Overview
The MiCS-5524 is a compact and robust MEMS gas sensor designed for indoor carbon monoxide and natural gas leakage detection. It is also suitable for indoor air quality monitoring, breath checking, and early fire detection applications. Its small footprint and high-volume manufacturing make it ideal for low-cost, compact designs in harsh environments.

Detectable Gases and Ranges:
- Carbon monoxide (CO): 1 1000ppm
- Ethanol (C2H5OH): 10 500ppm
- Hydrogen (H2): 1 1000ppm
- Ammonia (NH3): 1 500ppm
- Methane (CH4): >1000ppm
- Hydrogen Sulfide (H2S): Not specified range
- Propane: Not specified range
- Iso-butane: Not specified range
Important Precautions:
- The sensor must be reflow soldered in a neutral atmosphere, without soldering flux vapours.
- Avoid exposure to high concentrations of organic solvents, silicone vapours, or cigarette-smoke to prevent poisoning the sensitive layer.
- Heater voltage above the specified maximum rating will destroy the sensor due to overheating.
- The sensor should be placed in a filtered package to protect against water and dust projections.
- Use ESD protection equipment when handling the sensor.
Measurement Circuit Notes:
- RLOAD must be 820 at the lowest to avoid damaging the sensitive layer.
- A resistor (R) of 82 is necessary for the heater to obtain the right temperature when using a single 5V power supply.
Packaging:
- Dimensions: 5 x 7 x 1.55 mm
- Available in tape and reel packaging.
- Cavity dimensions: 5.5 x 7.5 x 2.55 mm (tolerance +/- 0.2 mm).
- Reel dimensions: 178 mm (max 700 sensors) or 330 mm (max 2000 sensors).
