AnyLeaf: Cutting-edge SUAS hardware
AnyLeaf – PH Sensor for Microcontrollers launched on September 4, 2020 with 90 votes, #459 of 3,898 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 6 years on.
In plain words
AnyLeaf is a pH sensor designed for use with microcontrollers. It allows users to measure acidity and alkalinity levels in liquids through electronic devices. The sensor is suitable for makers, engineers, and hobbyists working on projects that require pH monitoring, such as aquariums, hydroponics systems, or scientific experiments. Its main advantage is compatibility with microcontroller platforms, enabling easy integration into DIY electronics projects.

From the sources
Available with lab-grade pH probe. Connects directly to your device (Arduino, Raspberry Pi, or embedded) - no other parts required. Our open-source software makes measuring fast and easy. Includes temperature compensation, with built in sensor. Can be used with Oxidation Reduction Potential(ORP) , and other ion-selective electrodes. (Nitrate, Potassium, etc) probes. This module can be used with any probe with a BNC connection. The I2C interface can communicate with nearly any microcontroller. C++: Download Anyleaf.cpp and Anyleaf.h from the C++ Github link below, and place them in your project directory Python: Run sudo apt install python3-scipy , then pip3 install anyleaf .

Almost eight years ago I launched an online “Linux sysadmin course for newbies” here at HN. It was a side-project that went well, but never generated enough money to allow me to fully commit to leaving the Day Job. After surviving the Big C, and getting made redundant I thought I might improve and relaunch it commercially – but my doctors are a pessimistic bunch, so it looked like I didn’t have the time.
