Description: With our design, it takes two readings by the RCX to get one complete reading from the compass sensor. Software then must combine those readings together to determine the angle the compass is pointing. We had to do it this way because of power demands by the Dinsmore part and power limitations of the RCX. More: The Dinsmore compass sensor has two outputs that need to be combined to know the direction you are pointing. Figure 1 shows the compass outputs as they look across a 360 degree turn. It took me a while to make sense of the compass sensor outputs.
The described system involves a Dinsmore compass sensor, which is utilized to determine directional orientation. The sensor produces two distinct outputs that must be processed to yield a single, accurate compass reading. The readings are obtained through an RCX microcontroller, which facilitates the integration of the sensor data.
In operation, the RCX microcontroller captures two sequential readings from the compass sensor. These readings are essential for calculating the angle of orientation relative to magnetic north. The combination of the two readings is necessary due to the inherent power constraints associated with the RCX and the Dinsmore sensor's power requirements. This design choice ensures that the system operates efficiently while still providing reliable directional information.
The outputs from the Dinsmore compass sensor are typically represented as analog voltage levels, corresponding to the compass orientation across a full 360-degree rotation. The software implemented on the RCX is responsible for interpreting these voltage levels, converting them into a usable format, and performing the necessary calculations to derive the final compass heading.
To visualize the sensor outputs, a graphical representation (referred to as Figure 1) would typically illustrate the variations in output voltage as the sensor is rotated. This graphical data can aid in understanding the relationship between the compass sensor's outputs and the physical orientation it represents.
Overall, the design effectively balances power consumption with the need for accurate and reliable compass readings, making it suitable for applications where power resources are limited.With our design, it takes two readings by the RCX to get one complete reading from the compass sensor.
