|
||||
[Flipper Zero](https://flipperzero.one/) application for reading temperature, humidity and pressure sensors using Onewire, Singlewire, I2C protocols.
|
||||
## List of supported sensors (supplemented)
|
||||
|
||||
|
||||
## Installation
|
||||
Copy the contents of the repository to the `applications/plugins/unitemp` folder and build the project. Flash FZ along with resources. [More...](https://github.com/flipperdevices/flipperzero-firmware/blob/dev/documentation/fbt.md)
