Selecting a Sensor

One key benefit of TIMSS is the ability to select a sensor and generate expected device outputs (Figure 2-8). Devices available for simulation are located at Magnetic Sensors on TI's website and up to 6 devices can be selected. This step can be skipped if only the magnetic field profile is needed.

The full portfolio of products includes several different device package options and device families. The search function is available to assist with sensor selection by name. The filter menu is expandable to select options that only show devices that match the specified settings (Figure 2-9). Selecting the Featured Devices tab opens a list of commonly recommended devices for the appropriate motion type.

Each tile expands when hovered over with a mouse to reveal a More Info button with more information about the devices. An info graphic showing the device block diagram is loaded and a link to the product page is available when More Info is selected. The Product Page link leads users to the device data sheet, application notes, and additional resources (Figure 2-10).

Selecting a sensor tile adds the sensor to the Selected Sensor pane and up to six devices can be used in any simulation. The sensor quantity (Figure 2-11) can be increased in this pane if more than one sensor of a particular product is needed. Sensor selection can be skipped to produce a simulation that includes only the magnetic field input. The user is free to update the sensor selection and quantity after creating a new simulation.
