The module;s digital outputs can be user-defined, specific methods are as follows:
1. Press and hold S1 button for 3 seconds, display appears LLL.
2. S1 button is pressed, showing the emergence of a number (such as 100 by default), the minimum measurement limit, when the measurement time is less than this value, OUT2 will output a high level, probably in the 4.5V or so. The minimum measurement limit allows users to increase at S2, S3 decreased to change.
3. When setting the minimum measured value, then click the S1 key, display appears HHH, the maximum measurement limit of the setting, press the S1 button to display the data (such as 200 by default), the maximum measurement limit. When the measured distance is greater than this value, when, OUT1 will output a high level, probably in the 4,5 V or so. The maximum measured limit allows users to increase at S2, S3 decreased to change.
When setting the maximum measured value, press the S1 button to save the values you set with a power failure (it is powered off, which value is unchanged)
