7.18 Sensors
This function allows you to set the transmitter, internal receiver and data returned by the external sensor.
7.18.1 Display Sensor
This list shows all sensors connected to the receiver, including
sensor type, number and real-time data. This list can also be
accessed quickly from the home screen.
[Type] shows the sensor type.
[number] display sensor's number.
•
The first sensor in the list by default is the TX Voltage sensor,
however receiver, signal strength indication, RSSI, noise,
signal to noise ratio can also take this slot.
•
No. 2 is the first external sensor connected to the receiver;
the receiver supports up to 15 sensors.
This list data is displayed in real time. When the receiver is
connected to a sensor, this list will be refreshed to display the new
sensor’s data.
[Value] displays the data returned by a sensor.
[TX Voltage]: Displays the voltage for the transmitter's battery.
[RX Voltage]: Displays the power supply voltage for the receiver.
[Signal strength]: refers to the strength between the transmitter and the receiver. It is calculated by using SNR. The
signal strength will be displayed as a value between 0 and 10. If the signal strength drops to 4 or below the system
will alert the user.
[Signal to Noise Ratio]: The signal-to-noise ratio refers to the decibel difference between the signal and the noise
received by the receiver. The signal-to-noise ratio = RSSI-noise, which is a decisive parameter in the overall quality
of the signal. If the SNR drops below 11 reduce the range quickly to prevent loss of control.
[RSSI]: RSSI is used to measure signal strength between the receiver and the transmitter.
[Noise]: Noise is generated due to interference from other nearby transmitters such as WI-Fi. In places where there
are too many transmitters, excessive noise will affect the maximum range for a flight.
