+Sleep Mode
+----------
+The sensor idle power consumption is roughly 20mA. If you plan to keep the device running continuously, it is wise to implement the Sleep Mode, which puts the sensor to sleep (power off) a few seconds after the last communication (configurable with ``idle_period_to_sleep``). It can only be implemented along with the Touch Sensing Feature, since it uses the touch feedback to wake up the sensor.
+To implement this feature, you will need one more free GPIO pin to toggle the sensor power on and off and two external components: a 10kOhms resistor and a PNP transistor (like a BC327).
+
+This is a wiring example for the R503 and below you can find the respective configuration:
