PhysLogger - An overview

PhysLogger is a family of hardware devices and software tools that can measure and control a range of physical quantities—letting you fully discover the underlying scientific concepts of experiments without getting lost in mundane or difficult steps!

PhysLogger enables oneself to measure, analyze, and control physical quantities with live plots and interactive widgets. It is a combination of a pocket sized PhysLogger device, a rich desktop application, and a suite of sensing and controlling devices we call PhysInstruments.

In a typical application, using self-guided tours in the PhysLogger desktop application, one can set up several instruments connected via USB-C style connectors to the PhysLogger. Physical quantities like temperature, voltage, force, magnetic flux, intensity, and sound level can be viewed as time plots on the screen with just a few clicks.

PhysLogger records physical quantities using a pocket sized device and displays it on computer screen for measurement and analysis.


Don’t just be a bystander, surge into and impact processes by controlling basic physical quantities.


PhysLogger requires a computer once to be configured for a particular setup. However once set-up, it retains this configuration even when the computer has been removed! This is how PhysLogger brings the analysis and innovation together under one roof.

Use our modular PhysInstruments , open-source facilities, and this forum to reconfigure these tools for multiple kinds of investigations, build your own experiments, provide feedbacks, and offer improvements.

PhysLogger is a data acquisition and logging device. Augmented with a complete suite of conditioned sensors, an intuitive and refreshing interface, and buttressed by rapid, community support, the PhysLogger family aims to liberate. It frees us from the need to buy expensive equipment, long wait times, and gives a paradigm shift through a modular tapestry of scientific articles that can be reconfigured to create altogether new experiments, and scientific instruments.
