We tested popular wideband O₂ controllers against lab-grade equipment to see how accurate their lambda readings really are under real engine conditions.

The EV3 using UART protocol to communicate with sensors, and SPIKE Prime/Robot Inventor(Powered Up devices) using same protocol with some new extensions. So that we can build a simple adapter to ...

Abstract: Aiming at the demand of oxygen partial pressure measurement in aerospace and aviation, a tunable diode laser absorption spectroscopy (TDLAS) technique is proposed to realize the oxygen ...

Abstract: This work presents a miniaturized electrochemical sensor-integrated bioprocess monitoring pod (bPod) that wirelessly monitors local dissolved oxygen (DO) saturation within bioreactors in ...

ioBroker needs special permissions to control GPIOs. On most Linux distributions this can be achieved by adding the ioBroker user to the gpio group.
