SparkFun has introduced the launch of a brand new environmental sensor breakout board, based mostly on its current Bosch Sensortec BME280 board however now boasting a ScioSense ENS160 fuel sensor alongside it.
“The SparkFun ENS160/BME280 Environmental Combo Breakout takes care of all of your atmospheric-quality sensing wants with the favored ENS160 and BME280 ICs,” SparkFun’s Chris McCarty writes of the corporate’s newest launch. “To make it even simpler to make use of this breakout, all communication is enacted solely by way of I2C, using our helpful Qwiic system. Nonetheless, if you happen to favor a breadboard, we nonetheless have broken-out 0.1in. spaced pins.”
The “combo” a part of the breakout board’s title refers, in fact, to the 2 sensors on board. The Bosch Sensortec BME280 takes care of temperature, relative humidity, and barometric strain; the ScioSense ENS160 screens equal carbon dioxide (eCO₂) and whole unstable natural compounds (TVOCs) in elements per million and elements per billion respectively — and may mix the 2 to generate an Air High quality Index (AQI) worth.
The ENS160, which replaces the end-of-life CCS811, comes with one other trick up its sleeve: “The ENS160 additionally has a characteristic that permits it to fine-tune its readings if it may well entry the present humidity and temperature,” McCarty explains, which is one thing the BME280 is able to present. “This permits the sensors to work collectively to present us extra correct readings than they’d be capable of present.”
The board is now obtainable to order on the SparkFun retailer at $29.95 earlier than quantity reductions; McCarty notes that it comes with its I2C addresses preconfigured, and necessitates the usage of a multiplexer to arrange multiple breakout board on a single I2C bus.
