Multi-gas sensors in stock at DigiKey

The sensors are in stock at authorised distributor DigiKey.

Both ENS160 and ENS161 combine the detection of a wide range of gases, including volatile organic compounds (VOCs) and oxidizing gases, with intelligent on-chip algorithms.

The sensor calculates a series of fully processed outputs such as CO₂ equivalents (eCO₂), total volatile organic compounds (TVOC) equivalents (eTVOC), and a 5-step air quality index (AQI) according to the German Environment Agency, Umweltbundesamt (UBA) (AQI-U), while the ENS161 additionally provides a 500-step relative AQI according to ScioSense (AQI-S) output.

While all this is done on-chip with no required libraries or additional overhead for external controllers or processors, the ENS161 introduces low-power operating modes.

By lowering the sample rates of the sensor, low-power and ultra-low-power modes can be offered, reducing average current consumption to 700 µA or 150 µA, respectively.

In addition to traditional smart home and building applications, this opens up wearables, battery-powered devices, smart things, and IoT applications to integrate air quality sensing in a space-saving 3 mm x 3 mm LGA package.

Applications include air purification and home automation; HVAC, demand-controlled ventilation systems; building automation; appliances, cooker hoods; smart thermostats; wearables and battery-powered devices and smart things and IoT devices.
