The intelligence lives in the sensor
Intelligent Smart Sensor - making the platform possible.
The SA2 Smart Sensor Module combines conventional gas sensing technology with advanced signal processing for diverse safety and environmental monitoring applications. Each module carries a gas detection sensor plus a microprocessor-based conditioning circuit with embedded analytics. Factory programmed for a specific gas and sensitivity range, the SA2 is housed in an RFI/EMI-resistant metallic enclosure with gold-plated pins. A uniform I²C register map across sensor technologies enables OEM standardization and plug-and-play compatibility with smart transmitters and control systems.
Also available separately for integration into your device.
