Kitronik air quality data logging card for Pico

Description

The Kitronik Smart Air Quality Board for Pico provides a complete air monitoring and reporting solution for the Raspberry Pi Pico.

Name: "Kitronik Air Quality Datalogging Board for Pico"

The variety of integrated sensors and connection points allow you to effectively log, store and display data using the Pico file system and an OLED screen. There are also connection points for external devices such as analog sensors, servos, motors and heating plates.

The board includes a double row of pin sockets to connect your Raspberry Pi Pico. The Pico can then read inputs from a BME688 air quality and environmental sensor (temperature, pressure, humidity, air quality index and eCO2). The sensor, as well as the RTC and flash memory on the Pico, means that the board is well set up for data logging. There is a black and white 128x64 OLED screen and 3 status ZIP LEDs for visual display of data, a piezo buzzer for audio and two buttons for user input. There are also external connections: 2 1A outputs, a servo output, an expansion connector for more ZIP LEDs, and analog input connectors connected to the pico ADC (various other pico pins are split to 0.1-inch solder pads as further inputs and outputs, along with pads for 3V and GND).

Power is supplied via the 3xAA battery holder or the "POWER" terminal block. The power supply is controlled by a power switch, with a green LED indicating when the board is switched on. The Pico also generates a regulated 3V supply which is used to power the BME688 sensor and OLED screen.

The "POWER" terminal block can also be used as a connection point for a solar cell. NOTE: Please ensure that the correct batteries are inserted before charging. They should be NiMh batteries.

Kitronik has a MicroPython module to support the use of the Smart Air Quality Board. This can be found together with example programs and a complete README document on the Kitronik GitHub .
