Notable features include multi-gas detection and detection powered, contributing to its time-tested character.
Key Features
- [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 (NO2: 0.05-10ppm), Ammonia (NH3: 1-500ppm), Ethanol/VOCs (10-500ppm), Hydrogen (H2: 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.
- All MEMS gas sensors exhibit cross-sensitivity to various gases. This module is ideal for qualitative trend analysis, TinyML electronic nose projects, and IoT prototyping rather than industrial-grade absolute measurement. It requires a 24-hour initial burn-in and a few minutes of preheating upon each power-up for stable readings.
