Arduino expert

We are looking for an Arduino expert. Various sensors such as temperature sensors, humidity sensors, motion sensors, etc. must be controlled. The sensor data should be collected by the Arduino and passed to a higher-level device manager. The task is therefore to control the sensors and write an interface with which the sensors can be queried by the higher-level device manager.
In addition, a protocol of the interface must be written. Should be programmed in C or C++. A GUI is not required.
