Gravity: MiCS-4514 Multi-Gas Sensor Module for Arduino / ESP32 / Raspberry Pi | I2C MEMS Air Quality Sensor Detects CO NO2 NH3 Alcohol H2 CH4 | Built-in Algorithm ppm Output for DIY IoT Projects

[MULTI-GAS DETECTION] Powered by the MiCS-4514 MEMS sensor, this single module simultaneously measures the concentration of
Carbon Monoxide (CO: 1-1000ppm), Nitrogen Dioxide (NO 2: 0. 05-10ppm), Ammonia (NH 3: 1 -500ppm), Ethanol/VOCs (10-500ppm), Hydrogen (H 2: 1 -1000ppm), and
Methane (CH4: >1000ppm).. [ONBOARD MCU & DIRECT ppm OUTPUT] Unlike raw analog gas sensors that rely on a host microcontroller for complex ADC sampling, this module features an independent onboard MCU pre-programmed with concentration conversion formulas. It streams estimated ppm data directly via the I2C bus, ensuring consistent accuracy across any microcontroller and saving hours of firmware tuning.. [PLUG-AND-PLAY, NO SOLDERING] Equipped with the standardized Gravity 4-pin I2C interface and an included foolproof cable, the sensor can be connected in seconds. Open-source Arduino libraries are available, enabling rapid prototyping and TinyML "Electronic Nose" projects.. [COMPATIBLE WITH ARDUINO, ESP32 & RASPBERRY PI] With a 3.3V to 5.5V wide operating voltage and low power consumption, the module is fully compatible with Arduino, ESP32, and Raspberry Pi. Its compact 27x37mm footprint and durable MEMS design ensure a stable lifespan for long-term environmental monitoring nodes.
