5.10 Power saving mode
TF-Luna supports power saving mode for power sensitive applications, it reduces its power
consumption by adjusting both current level and duty cycle of the light source. With 5V power supply,
TF-Lunas power consumption on Continuous ranging mode is about 350mW as the light source switch to
highest current level and duty cycle.
When TF-Luna is on power saving mode, it dynamically adjusts the current of the light source by
switching several preset current levels according to the strength (amp) of the receiving signal. Therefore,
TF-Luna can get a stable amp value and save power consumption at the same time.
Users may reduce the duty cycle in different ways: to use trigger mode (about 42.5mW with 5V power
supply) to turn the light source off while waiting, or to enable power saving mode. Power saving mode
also turns the light source off, but it lets TF-Luna generate trigger signal periodically and automatically.
The maximum sample frequency that gives TF-Luna a stable timing is 10Hz.
Please follow the format inEnable/disable Power saving mode (ECO)
ID_LOW_CONSUMPTION=0x35 section to enable power saving mode with listed working frequencies.
The average current and power are measured with 5V power supply and the actual value might be
different in various environment, especially different temperature or other power supply.
