Sonar Sensor Ranging Equation
Equation
| Variable | Description | Units |
| d | distance | inches |
| p_t | pulse time | microseconds |
| 12.0 | conversion | inches/ft |
| 1116.4 | speed of sound at 14.44 C | ft/s |
| 2.0 | conversion | pulse time is to target and back to sensor |
| + 100 | delay for the SRF05 receiver to become active | microseconds |
| Equation | ||
| d = ( ( (p_t + 100) / 1116.4) / 2.0) * 12.0 | ||
