Figure 5-11. Proximity Sensor in Proximity State
Note: In the Proximity state, the LED brightness increases.
Figure 5-12. Proximity Sensor in ON State
In this state, the buzzer is also enabled.
Note: The EZ-Click customiser tool computes the SNR. To establish a reliable noise range, the tool
should be allowed to collect data samples for at least 30 seconds before a button press or proximity
sensor state change. If sufficient noise samples are not collected, the EZ-Click tool reports an error
and extremely high values for SNR.
