Product Description
Product Description
The DFRobot Fermion: MEMS H2 & NOx Gas Detector - MiCS-2714 Sensor (1-1000ppm, Breakout) is a compact gas sensor module built around the MiCS-2714 MEMS sensing element. It is intended for detection of hydrogen and nitrogen oxides and provides an analog 0-5V DC output signal. This makes the module suitable for direct interfacing with microcontrollers, single-board computers, or other control and monitoring hardware with analog input capability.
The module operates from 5V DC with a tolerance of ±0.1V and has a power consumption of 0.45W. This corresponds to an approximate maximum operating current of 90mA. The specified environmental range covers -30°C to 85°C and up to 95% RH non-condensing. According to the source data, the response time is less than 30 seconds, and the expected service life is more than 2 years under normal use.
