# Common Telemetry Sensors

The following sensors are commonly used and normal automatically detected by EdgeTX:

{% hint style="info" %}
Each sensor has two auto generated sensors for their minimum and maximum values. They share the same name with a negative and positive symbol added to the end. For example: **RXBt +** This dispalys the maximum value that the sensor attained during the flight. Using the [Reset Telemetry](https://zkl2333.gitbook.io/edgetx-user-manual/v2.11-en/color-radios/reset-telemetry) or Flight function will reset this value to 0.
