Are you looking to buy RadioMaster ERS-BA01 Precision Barometric Altitude Sensor for ELRS System in Australia?
The ERS-BA01 Barometer Sensor provides accurate, real-time altitude data for compatible ExpressLRS receivers. By capturing barometric pressure and converting it into precise relative altitude information, the ERS-BA01 delivers reliable telemetry back to your EdgeTX radio. This sensor provides clear, responsive altitude monitoring.
As part of the ERS sensor family, the ERS-BA01 also supports pass-through expansion, allowing easy daisy-chaining with additional telemetry modules.
Features
- Real-Time Altitude Telemetry: Converts barometric pressure measurements into accurate relative altitude data for instant feedback on your radio.
- Expansion-Ready Pass-Through: Includes an in-and-out port for daisy-chaining additional ERS sensors without rewiring your setup.
- Seamless ExpressLRS Compatibility: Integrates easily with supported ExpressLRS PWM receivers via CRSF for fast and dependable data transmission.

Using Sensors with Non-Plug-and-Play PWM ExpressLRS Receivers
Most PWM ExpressLRS receivers are fully compatible; those without a dedicated UART port require reconfiguration to support external sensors (e.g., for telemetry). To enable this, reassign two PWM output pins as a serial UART—one for TX and one for RX—via the receiver's Web UI (accessed by putting the receiver into WiFi mode) or via the ExpressLRS LUA script. This enables sensor connectivity while preserving the remaining PWM channels for servos or ESCs.
