Radiomaster ERS-BA01 Barometrischer Höhenmesssensor

RadioMaster ERS-BA01 is a compact barometric altimeter sensor designed for ExpressLRS receivers. It is primarily intended for PWM ELRS receivers used in unmanned aircraft models. The sensor connects via UART interface and communicates using the CRSF protocol. It is compatible with Radiomaster ER6, ER8, ER8G, and ER8GV receivers as well as other ELRS receivers with an available UART port. With the UART input and output, it is possible to chain multiple sensors together.

ERS-BA01 measures barometric pressure and converts it to relative altitude. 

For sensor configuration and proper telemetry display on transmitters with the EdgeTX firmware, the LUA script RadioMaster Sensor Configurator is used, allowing parameter settings and data logging for later analysis.
