Minidis is proactively testing and developing field sensors for IOT and industrial usage. 

We offer both wired (RS-485, ModBus, RS-232, USB, or GPIO/DAC based) as well as wireless sensors (WIFI, Bluetooth, 4G/5G/NBioT, Lora)

Since we do a lot of customisation and design, below list is certainly not comprehensive.
Almost every aspect you can imagine can be metered with a sensor. Just contact us if you have a specific solution mind.
