Volker Ziemann · KTH Publication Database DiVA (KTH Royal Institute of Technology) · 2017
We describe a system that interfaces a SM-24 geophone to a NodeMCU micro-controller and allows to display spectrograms on any web browser. The independent sensor nodes can be very exibly placed anywhere because they are battery-powered and connected to the network by WIFI. The presentation software is based on Javascript and can be used in an Internet browser on any computer connected to the same network.
