The ZMOTION
overall operation. It operates in two basic modes:
Hardware Interface Mode
Hardware Interface Mode provides the simplest mode of operation and allows basic control of
the ZMOTION
the serial interface is disabled and the trim pots on the Evaluation board (Sensitivity, Delay
and Ambient Light Threshold) are used to control operation.
To enable Hardware Interface Mode and test out the basic operation:


1. Place SW1 in the ‘HARDWARE’ position
2. Turn the Ambient Pot fully clockwise (towards ‘+’) to set the ambient light threshold to
3. Turn the Delay Pot fully counter-clockwise (towards ‘-‘) to select minimum LED on time
4. Turn the Sensitivity Pot fully clockwise (towards ‘+’ to select maximum motion detection
5. Press Reset or apply power.
6. After power-on, the ZMOTION
7. Create some motion in front of the ZMOTION

At this point the ZMOTION
applied to the TXD/SNS pin to determine the Interface Mode. With SW1 in the
“HARDWARE” position, the voltage on this pin will be between 0V and 1.8V, selecting

the ambient light threshold, delay and sensitivity are monitored continuously.

seconds up to a maximum of about 30 seconds.
