I published another small command-line tool for Raspberry-Pi. This time one to read data from the Sensirion SGP30 sensor. While you can communicate over I2C with sensors using Python, I found it not as reliable as using compiled C or C++ programs. To combine the two worlds, I started writing really small command-line tools, which…

“Read SHT31” Command-Line Tool
For various sensors, attached to Raspberry-Pi computers, I wrote small command-line tools to read the sensor values over the I2C connection. While you can do this with a Python script directly, I found using a compiled C or C++ program accessing the low-level device more reliable. The program I publish today, reads temperature and humidity…
Tiny Particle Sensor Node with Decorative Case
This article is about a small sensor node with a decorative case. It is based on the Raspberry Pi Zero W board with a custom sensor shield. I publish all hardware files for a simple sensor version, so you should be able to build this kind of sensor node and use it to monitor anything…
