OAT sensor 428 of MGL Avionics¶

../../_images/oat_sensors.png — **OAT sensor 428**¶

The OAT sensor 428 of MGL Avionics is an analogical temperature sensor that measures temperatures from -55°C to 150°C. It changes the voltage according to the temperature measured and therefore the connection to the autopilot is performed using the ADC pins.

Hardware installation¶

The following resistors and wiring are necessary to connect an OAT sensor 428 to the Autopilot 1x:

Autopilot 1x Connections
Pin number	Signal	Harness wire colour
36	5V	Pink
37	GND	Blue
38	ANALOG_1	Red

Software installation¶

Once connected the OAT sensor, the temperature can be monitored with Veronte software using the variables ADC1 to ADC5.

The necessary configuration of Veronte Autopilot 1x for OAT sensors require different applications, according to the software version:

6.8 or higher: use 1x PDI Builder reading its user manual. Go to 1x PDI Builder manual -> Integration Examples.
