FrSky Smart Port RPM and Temperature Sensor
The FrSky Smart Port RPM and Temperature Sensor is a dual-function telemetry sensor that integrates seamlessly with FrSky's Smart Port protocol to provide real-time engine RPM monitoring and ambient temperature data for RC aircraft, drones, and multirotor systems. Professional drone pilots, RC aircraft enthusiasts, and UAV operators rely on this sensor to monitor critical engine parameters and environmental conditions during flight operations. This sensor solves the critical problem of blind monitoring by delivering accurate telemetry feedback directly to your transmitter, enabling informed flight decisions and early detection of engine anomalies before they become catastrophic failures.
Product Overview
The FrSky Smart Port RPM and Temperature Sensor operates on the proprietary Smart Port half-duplex serial communication protocol, which allows multiple sensors to share a single data line without signal interference or crosstalk. The RPM measurement utilizes a high-frequency pulse detection circuit that counts engine rotation cycles with microsecond-level precision, capable of measuring rotation speeds from near-zero to over 100,000 RPM with exceptional accuracy. The temperature sensor employs a precision thermistor with linearized output, providing temperature readings across a -40°C to +85°C range with ±2°C accuracy, making it ideal for monitoring motor windings, engine casings, or ambient air conditions during extended flight missions.
What distinguishes this sensor is its intelligent signal conditioning and noise rejection architecture, which filters electromagnetic interference from high-current brushless motor controllers and ignition systems. The sensor features a compact, lightweight design (approximately 7 grams) with integrated protection circuitry against voltage spikes and reverse polarity, ensuring reliability in demanding aerial platforms. The dual-sensor integration eliminates the need for separate devices, reducing weight penalty and simplifying wiring complexity in space-constrained airframes while maintaining independent calibration for each measurement channel.

- Multirotor drones with brushless motor systems needing motor temperature monitoring to detect thermal runaway conditions and optimize cooling strategies for extended flight operations
- Hybrid-electric aircraft platforms combining combustion engines with electric motors, requiring simultaneous RPM and temperature telemetry for power management and thermal load balancing
- UAV research and development projects requiring precise telemetry data logging for performance analysis, parameter tuning, and post-flight diagnostics of propulsion systems
- Racing drone platforms monitoring motor winding temperatures to prevent thermal throttling and maintain consistent thrust output during high-speed competitive flights
How to Use
Installation begins by identifying the Smart Port telemetry port on your FrSky receiver or telemetry hub, which is typically labeled with three pins: signal, voltage, and ground. Connect the sensor's Smart Port connector directly to an available Smart Port pin, ensuring proper orientation to avoid reverse polarity damage. The sensor requires operating voltage between 3.5V and 9.6V DC, which is typically supplied through the receiver's regulated power rail. Mount the temperature sensor probe in close thermal contact with the component you wish to monitor, such as the motor case or engine cylinder head, using thermal adhesive or mechanical fastening to ensure consistent readings.
For RPM measurement, position the sensor's magnetic pickup coil within 5-10mm of the rotating shaft or propeller, ensuring the magnet or ferrous target passes directly through the sensor's detection zone on each rotation. In your transmitter's telemetry configuration menu, add the RPM and temperature sensor to your telemetry page display, and the sensor will automatically be discovered by the Smart Port protocol. Calibration is typically automatic, but verify initial readings against known reference values during ground testing before flight operations. Monitor telemetry data during test flights to establish baseline values and alarm thresholds appropriate for your specific aircraft configuration and operating parameters.
Frequently Asked Questions
What is the maximum RPM this sensor can accurately measure?
The FrSky Smart Port RPM and Temperature Sensor can reliably measure rotation speeds up to 100,000+ RPM with ±1% accuracy. The practical upper limit depends on the magnet placement and sensor mounting geometry, but most applications using standard RC propellers and brushless motors will operate well within this range. For extremely high-speed applications exceeding 100,000 RPM, consult FrSky technical specifications for your specific receiver model.
Can I use this sensor with multiple motors on the same aircraft?
Yes, FrSky's Smart Port protocol supports multiple sensors on a single data line through intelligent addressing. However, you will need separate RPM/Temperature sensors for each motor you wish to monitor. Each sensor connects to the Smart Port and transmits its data independently. For aircraft with multiple motors, you can install multiple sensors and assign each to a unique telemetry slot in your transmitter configuration menu.
What is the temperature sensor's response time?
The thermistor-based temperature sensor has a response time of approximately 1-2 seconds to reach 63% of a step change in temperature. This response time is adequate for monitoring thermal trends and detecting overheating conditions in real-time during flight. For applications requiring faster response times, consider mounting the sensor probe directly in thermal contact with the heat source rather than at a distance.
How should I mount the temperature probe for accurate readings?
Mount the temperature sensor probe in direct contact with the component being monitored using thermal adhesive, epoxy, or mechanical fastening. Avoid mounting in air gaps or using thermal barriers, as these will significantly increase response time and reduce accuracy. For motor temperature monitoring, attach the probe to the motor case. For engine temperature monitoring, secure it to the cylinder head or exhaust manifold area using high-temperature adhesive rated for your operating temperature range.
Is this sensor compatible with all FrSky receivers?
The FrSky Smart Port RPM and Temperature Sensor is compatible with all FrSky receivers featuring Smart Port telemetry ports, including the D series, X series, and R series receiver families. Verify that your specific receiver model supports Smart Port protocol before purchase. Some older FrSky receivers using only S.PORT may require a Smart Port adapter or hub for compatibility.
