The version 4 SIMB3 inherits the SIMB3 V3 sensor suite, but replaces the Bruncin temperature string with a custom embedded string. The embedded string has fewer temperature sensors (160 as opposed to 192) but is higher precision (0.01 C instead of 0.125 C).
| Sensor | Field | Precision | Accuracy |
|---|
| Air Temperature | air_temp | 0.1 C | +/- 0.5 C |
| Barometric Pressure | air_pressure | 0.1 mBar | +/- 1 mBar |
| Latitude | latitude | ~ 0.1 m | 3 m |
| Longitude | longitude | ~ 0.1 m | +/- 3 m |
| Water Temperature | water_temp | 0.01 C | +/- 0.5 C |
| Surface Rangefinder | surface_distance | 0.01 m | +/- 0.001 m |
| Underwater Rangefinder | bottom_distance | 0.01 m | +/- 0.01 m |
| Embedded Temp String | dtc_values_0-159 | 0.01 C | +/- 0.5 C |
