The Uberlogger data-acquisition system is a simple, yet powerful high-performance logging device. It can log 8 analog channels and 6 digital inputs in CSV format directly to an SD-card. You can select the analog channel as either analog input or temperature input using an NTC temperature sensor. This way you can measure voltage and temperature simultaneously. The resolution can be set as either 12-bits or 16-bits and has a sample frequency ranging from 1 Hz till 250 Hz. The Uberlogger is configured through the web-based user interface which you can connect to through Wi-Fi, either using its hotspot functionality or through the client mode, which allows you to connect the Uberlogger to your own access point.

    I have finished my first version which I sell on my Tindie store. I still have some things I would like to improve:

    - A good 3D printed enclosure (maybe for a DIN rail as well?)

    - Wider sample range (<< 1 Hz and >> 250 Hz)

    - Trigger functionality

    - Timer functions

    - Output control

    - NTP server

    - Streaming API

    - MQTT and Home assistant support

    Maybe you have suggestions?
