Raspberry Pi Pico AMS Wireless Humidity Monitor

Raspberry Pico Wireless Humidity Monitor for your AMS

Maintaining optimal humidity levels is crucial for ensuring high-quality 3D prints. Excess moisture in filament can lead to issues like stringing, poor layer adhesion, and surface imperfections. We developed a compact, wireless humidity monitoring device within the Bambu Labs AMS module to address this. This device allows for real-time monitoring of humidity levels inside the filament storage area, ensuring the filament remains in ideal conditions.

Required Software 

To set up and run this project, you'll need the following software installed on your PC: 

1. Python: The server script that receives data from the Pico WH is written in Python. Install Python from the official website and ensure that It is added to your system's PATH during installation. 
2. Thonny IDE: Thonny is an Integrated Development Environment (IDE) that makes writing and uploading Python scripts to the Raspberry Pi Pico WH easy. You can download Thonny from the official website. After installation, you can use Thonny to write, upload, and run the script on your Pico WH. 
3. Driver for Raspberry Pi Pico: If you're using Windows, you might need to install a driver for the Raspberry Pi Pico WH. The driver allows your PC to recognize the Pico when connected via USB. The driver can be downloaded from the Raspberry Pi website. 

With these tools installed, you can set up your environment to program the Raspberry Pi Pico WH and run the server script on your PC.
