SGX MiCS-6814 Tri-Sensor Gas Breakout (CO, NO2, NH3)
The SGX Sensortech MiCS-6814 is a compact silicon MEMS metal-oxide gas sensor containing three independent sensing elements on one package. It detects carbon monoxide (CO), nitrogen dioxide (NO2), and ammonia (NH3) plus hydrocarbons, ethanol, propane, and hydrogen for air quality and automotive exhaust monitoring.
Architecture & Technical Specifications
Hardware Architecture & Features
- RED sensor element: measures carbon monoxide (1 to 1000 ppm), hydrocarbons, ethanol, and hydrogen.
- OX sensor element: measures oxidizing gases including nitrogen dioxide (0.05 to 10 ppm) and hydrogen.
- NH3 sensor element: measures ammonia (1 to 500 ppm), ethanol, propane, and iso-butane.
- Pure Engineering breakout PCB integrates an I2C analog-to-digital converter and heater control switches on a PUREmodules card-edge form factor.
Firmware, Software & Integration
- Digital I2C readout of all three gas channels and Independent heater power gating for low-duty-cycle battery operation.
- Compatible with the PUREmodules nRF52 CoreModule and Arduino I2C hosts.
