Traxxas Temperature & Voltage Telemetry Sensor, and is intended for use with the Traxxas XO-1. Temperature data is critical to monitoring performance, gauging the effects of changes, and preventing overheating. The Temperature Sensor features a precision thermistor and is installed on the motor or engine to continually monitor temperature as you drive. The Temperature Sensor can also be fitted to a speed control, battery, or exhaust pipe to monitor its temperature.
Traxxas "Long" RPM Sensor, and is intended for use with the Traxxas XO-1 1/7 Scale vehicle. To collect critical RPM data (Revolutions Per Minute), a "trigger magnet is installed in the spur gear of electric models, or the flywheel of nitro vehicles. To offset the weight of the magnet, additional material is molded or cast into the opposite side of the spur gear or flywheel. To read the magnet, a hall effect sensor is installed in the gear cover (electric models) or installed on a support arm (nitro models). Each time the trigger magnet passes the RPM sensor, a revolution is counted. Revolutions per minute are displayed on the tachometer of the Traxxas Link dashboard. RPM is also the key to determining your model's speed. When you select your model in the Traxxas Link application, the app uses your model's transmission ratio and tire circumference to calculate its speed based on RPM, and the speed is displayed on the Traxxas Link App's dashboard speedometer.
Voltage measurement isn't just for electric cars; the voltage of a nitro vehicle's on-board battery is also critical. An accessory voltage/temperature sensor is available to measure receiver battery pack voltage on nitro vehicles. To monitor the voltage of your electric vehicle's battery, the Power Tap Connector is installed over the speed control's Traxxas High-Current Connector. Battery voltage is measured and displayed as you drive, making it easy to see voltage drop under acceleration and monitor battery performance.
NOTE: In order to add telemetry to your Traxxas model, a TQi Radio System with Docking Base is required, as well as an iPhone or iPod with the Traxxas Link App installed. Most Traxxas kits require additional Traxxas chassis parts to install the telemetry system. Refer to your instruction manual
