The FrSky TEMS-01 temperature sensor monitors temperatures of model components such as motors, ESCs, batteries, engine cylinder heads, mufflers, regulators, and ambient air. The older FrSky Sensor Hub documentation describes using up to two TEMS-01 probes; the newer Advanced Engine Suite II (AES II) has three dedicated TEMS-type temperature inputs.
