About the product
Introduce
This kit is designed for MicroPython learning with raspberry pi Pico W. The kit includes the main board and some modules of the Mabee series ( Servo, Slide potentiometer, PIR sensor, CO2 sensor, Relay, MPU6050, Ultrasonic Ranging, ws2812). The mainboard base on the Pico W and LCD display, features three buttons, three LEDs and a buzzer. It also provides six interfaces to connect the peripheral modules.

- Click button "RUN" to run this script.
- The leds will light on and turn different colors circularly.
Mabee CO2 Demo
Mabee C02 can be used to measure the TVOC and eCO2, and use the measured temperature and humidity value to calibrate and ensure the VOA/eCO2 testing accurate and reliable. then we can query the measured value in other local devices Such as mobile phones, computers, etc.
- Click "stop" to reset the program.
- Connect the Mabee_CO2 sensor module to the CN3 port.
- Open the code "Project-10-CO2.py" in Thonny.
- Modify your Wi-Fi ssid and password in the code.
- Click button "RUN" to run this script.
- The webserver IP address and the CO2 concentration measured will be displayed on the LCD.
- You must link to the same Wi-Fi with the Pico w, which will put them on the same Local area network (LAN)
- After entering the IP address in the browser, the measurement results can be displayed on the web page.
Thingspeak Demo
Thingspeak is a IoT analytics platform. We can use the development board and its Peripheral equipment for collecting data and upload to the cloud. in this way, We can use this platform to make Visualization of data. At the same time, we can monitor these data on the internet.
- Click "stop" to reset the program.
- Due to the Pico w built-in Wi-Fi function, so you needn't connect any module.
- Open the code "Project-11-thingspeak.py" in Thonny.

- Click https://thingspeak.com/channels/1889504， You can see the result as follow.
Note: Click http://wiki.makerfabs.com/ESP8266_WiFi_Shield.html#iot-project, and it will teach you how to apply for a new thingspeak account.
PIR detection demo
PIR sensor Module: HC-SR501.
| Sensor | CN6 |
|---|---|
| Sensor's GND | CN6's GND |
| Sensor's DATA | CN6's GPIO16 |
| Sensor's VCC | CN6's VCC |
- Click "stop" to reset the program.
- Connect the PIR detection sensor module to the CN6 port, signal pin to GPIO16.
