The below options can be configured for sensors:
Name: Name of the sensor - up to 4 characters.
Type: Options are custom or calculated. Custom sensors are defined by the hardware. Calculated sensors are a sensors whose value is calculated using other sensors values. See below for more information on calculated sensors.
ID: This number indicates what type of sensore it is. It contains two parts. The first part is the ID number which defines the sensor type. The second part is the instance number for the hardware. If multiple sensors of the same type are configures, the instance numbers must be unique.
Unit: The unit for the sensor. This unit is used when the sensor value is displayed on the screen or read aloud.
Precison: Specifies the number of digits after the decimal point when the sensor value is displayed on the screen. The number is truncated based on this setting.
Ratio: Specifies the ratio value to multiply with the sensor value as needed by some sensors.
Offset: Specifies the offset value to add to the sensor value.
Auto Offset: When selected, the first received value is used as offset. You can use the Reset telemetry option to reset the offset on already configured sensors.
Positive: When selected, the value of the sensor will be displayed only when it is a positive number. Displays zero when the sensor value becomes a negative number.
Filter: When selected, the sensor value becomes a rolling average of the last 5 received values.
Logs: When selected, the value of this sensor will be saved in the log file. SD Card logging is configured in Special Functions or Global Functions.
Calculated sensors contain the additional configuration options:
Formula: Type of calculation to use. Options include:
Add: Add the values of up to 4 designated sensors.
Average: Calculates the average value of up to four designated sensors.
Minimum: Find the minimum value of up to 4 designated sensors.
Maximum: Find the maximum value of up to 4 designated sensors.
Multiply: Multiplies the value of 2 sensors.
Totalize: Calculate the cumulative value of one sensor.
Cell: This is the formula for FrSKY Lipo battery sensor. It displays cell voltage specified by the number in "Cell index" field. If you specify "Lowest" in "Cell index" field, the voltage of the cell with the lowest is displayed. If you specify "Highest" in "Cell index" field, the voltage of the cell with the highest is displayed. If you specify "Delta" in "Cell index" field, the voltage difference between lowest and highest cell is displayed
Consumpt: Calculates the power consumption (mAh) by cumulatively add the values of current sensor.
Distance: Calculates the distance between the receiver and the radio using GPS sensor and altimeter values.
Source 1, 2, 3, 4: The sensors that will provide the argument values that are used in the formula defined above.
Persistent: When selected the sensor values will be saved when switching between models or powering down the radio.
Telemetry is data received from the model to the radio from various sensors. These sensors may be in included in the radio receiver or flight controller, or may be separate sensors, such as GPS, variometer, or magnetometer. Telemetry data that is received can be displayed by EdgeTX in widgets, configured in alarms or audio call-outs.
All prevously configured sensors are listed here. Sensors that are highlighted have received data since the model was loaded or the telemetry values were reset. A small circle icon will flash to the left of the sensor value when it has received a data update. Sensor values in black designate the sensors that are receiving regular updates. Sensor values that are red are no longer receiving regular updates. See Recognized Sensors for a list of commonly used sensors in EdgeTX.
The following options are listed under the sensor list.
Discover New: When selected, it will look for new sensors on the model and automatically configure them.
Add New: When selected, it will create a new blank sensor for that must be configured manually.
Delete All: This option will delete all prevously configured sensors. Note: This button will not be visible if there are no sensors configured.
Show instance ID:
Ignore Instances: This options prevents mutltiple sensors from reporting the same telemetry data.
If you select a specific sensor, you will get the following options:
Edit: Allows you to edit the sensor's configuration options.
Copy: Creates a copy of that sensor.
Delete: Deletes that sensor.
See the Sensor Configuration Options page for detailed description of all the configuration options for setting-up or editing sensors.
Here you can configure the threshold for the RX alarms. The Rx-Stats label will change (Rx-Stats, RSSI, Rqly, Sgnl) depending on the protocol that is used with the model.
Low alarm - The threshhold value when the "RF signal low" voice prompt will be played. The recommended value is 45.
Critical alarm - The threshhold value when the "RF signal critical" voice prompt will be played. The recommended value is 42.
Disable telemetry alarms - When enabled, no alarm voice prompts will be played.
A variometer detects changes in the model altitude. EdgeTX can alert the user of these altitude changes by providing a rising/lower pitched tone. Use the Variometer menu on the Radio Setup page to set the actual frequency and volume of the tone to be played. The following options exist to configure the variometer alarm.
You will need to use a Vario Special or Global Function to enable this functionality!
Source - Specifies the sensor to use as the variometer. It is selected from the telemetry sensors added in Sensors section.
Range - Specifies the ascent/descent range that will trigger the change in the Variometer beeping pitch. If climb/descent rate is within the range specified here, beeping pitch will change according to that value. When it goes beyond the range specified here, beeping pitch will stop changing. Units are meters/second or feet/second based on the Units setting on the Radio Setup page.
Center - Specify the range for ignoring changes in climb/descent rates. When the climb/descent rate is within the range specified here, the beeping pitch will not change.
Tone/Silent - Specifies whether to beep when climb/descent rate is within the range specified by Center.
The following sensors are commonly used and normal automatically detected by EdgeTX:
| Name | Description | Data source |

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 or Flight function will reset this value to 0.
