DS1820 temperature measurement


Is there a way to read values ​​from a 1-Wire or i2c sensor and send it via the data link to the ground station?

Alternatively: is there a pass thru for serial data? in this case an Arduino would handle the 1-Wire communication and forward the data via rs232 to the APM.

I think about DS1820 sensors on each ESC, LiPo, motor…

Thanks in advance

There is an I2C port on both the APM2.5/6 and the PX4 IO module: copter.ardupilot.com/wiki/common-autopilots/
You would have to write a library routine to read the temp sensors and insert it into the MavLink telemetry stream.
