The Kitronik Smart Air Quality board provides a complete air monitoring and reporting solution for the Raspberry Pi Pico. The wealth of built-in sensors and connection points allows you to record, store and display data efficiently with the Pico file system and an OLED display. There are also connection points for external devices The board includes a dual row of pin headers for connecting the Raspberry Pi Pico. The Pico can then read inputs from a BME688 air quality and environmental sensor (temperature, pressure, humidity, air quality indicator and eCO2). The sensor, along with the RTC and flash memory in the Pico means that the board is well prepared for data logging. There is a 128×64 black and white OLED display and 3 ZIP status LEDs for visual display of data, a piezo transducer for audio and two buttons for user input Power is supplied via the 3xAA battery socket or the “POWER” terminal block. The power supply is controlled using a power switch, with a green LED indicating when the board is on. The Pico also generates an adjustable 3V power supply which is used to power the BME688 sensor and the OLED display Features: A complete air quality monitoring and reporting solution for the Raspberry Pi Pico Measures temperature, pressure, humidity, air quality index and eCO2. The board features a 128×64 black and white OLED display for visual display of data The sensor, together with the RTC and flash memory in the Pico means the board is well prepared for time-stamped data logging The board also features 3 ZIP status LEDs for visual data display, a piezo transducer for audio and two buttons for user input There is an integrated two-row connector for the Raspberry Pi Pico connector There are connection points for external devices The board also has a connection point for a solar cell that can be used with rechargeable batteries to keep your experiments running for longer
