HydroSense II Soil Moisture Measurement System

11.11 Brightness

This menu allows the brightness of the LCD backlight to be adjusted. Since the

backlight uses a significant amount of power, reducing the brightness will extend

battery life. In bright, sunny conditions, the backlight has very little effect and

generally doesn’t help readability, so the HydroSense II detects the ambient light

conditions and automatically turns off the backlight when exposed to bright

daylight. Using the left and right keys, set the brightness to an acceptable level.

Press OK to save or Back to quit.

11.12 Backlight On Time

The LCD backlight turns on whenever a button is pressed. This menu configures

how long it remains lit after each press. The Left and Right keys change the

period and OK will save it. Press Back to exit without saving.

Setting the backlight on time to “Always On” will increase average power

consumption significantly, similarly reducing battery life.

11.13 Light Sensing

In bright, sunny conditions, the LCD backlight has very little effect on

readability, so the HydroSense II detects the ambient light level and switches the

backlight off in bright conditions. This feature can be disabled using this menu.

Using the up and down keys, select ON or OFF from the list and press OK to

save the setting. Press Back to quit.
