Product Details
The Kitronik Smart Air Quality Board for Raspberry Pi Pico offers a top - notch air monitoring and reporting solution. It comes packed with a wide range of onboard sensors and connection points, enabling you to efficiently log, store, and display data using the Pico filesystem and an OLED screen. External devices like analogue sensors, servos, motors, and heater pads can also be easily connected. This board has a dual - row of pin sockets for your Raspberry Pi Pico. The Pico can read data from a BME688 air quality and environmental sensor, measuring temperature, pressure, humidity, air quality index, and eCO2. With the RTC and flash memory on the Pico, it's perfect for time - stamped data logging. A black and white 128x64 OLED display screen and 3 status ZIP LEDs visually show data, a piezo buzzer provides audio, and two buttons allow for user input. There are external connections too, including 2 1A outputs, a servo output, an extension for more ZIP LEDs, and analogue input connections to the Pico ADC. Other Pico pins are available on 0.1” pitch solder pads. Power can be supplied via a 3xAA battery holder or the ‘POWER’ terminal block, which can also be used for a solar cell. The power switch controls the voltage supply, with a green LED indicating when the board is on. The Pico supplies a regulated 3V for the BME688 sensor and OLED screen. Kitronik offers a MicroPython module on GitHub, along with example programs and a full README. Note that the Raspberry Pi Pico and AA Batteries are sold separately. This all - in - one solution measures key air quality factors, is great for long - term classroom experiments, and has dimensions of 74mm in length, 72mm in width, 28.7mm in maximum height, and a PCB thickness of 1.6mm.
Using the Kitronik Air Quality Datalogging Board for Raspberry Pi Pico is easy. First, connect your Raspberry Pi Pico to the dual - row pin sockets on the board. You can power the board using either the 3xAA battery holder or the ‘POWER’ terminal block. If you're using the ‘POWER’ terminal block, you can also connect a solar cell. Make sure to switch on the power using the power switch, and the green LED will light up to show it's on. Once powered, the Pico will start reading data from the BME688 sensor, including temperature, pressure, humidity, air quality index, and eCO2. The data will be displayed on the black and white 128x64 OLED screen, and you can also see visual cues from the 3 status ZIP LEDs. You can use the two buttons for user input, and the piezo buzzer will give you audio feedback. You can connect external devices like analogue sensors, servos, motors, and heater pads to the available connection points. Remember, the Raspberry Pi Pico and AA batteries are sold separately. When using rechargeable batteries with the solar cell, ensure they are NiMh. To keep your board in good condition, avoid exposing it to extreme temperatures or moisture. If you need help, check out the datasheet and the MicroPython module on Kitronik's GitHub, which also has example programs and a full README.
