The following wake up sources are demonstrated in this example (refer to the [Wakeup Sources documentation](https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/system/sleep_modes.html#wakeup-sources) for more details regarding wake up sources):
|
||||
|
||||
1. **Timer:** An RTC timer that can be programmed to trigger a wake up after a preset time. This example will trigger a wake up every 20 seconds.
|
||||
2. **EXT1:** External wake up 1 which is tied to multiple RTC GPIOs. This example use GPIO25 and GPIO26 to trigger a wake up with any one of the two pins are HIGH.
|
||||
3. **Touch:** Touch pad sensor interrupt. This example uses touch pads connected to GPIO32 and GPIO33 to trigger a wake up when any of the pads are pressed.
|
||||
2. **EXT1:** External wake up 1 which is tied to multiple RTC GPIOs. This example use GPIO2 and GPIO4 to trigger a wake up with any one of the two pins are HIGH.
|
||||
3. **Touch:** Touch pad sensor interrupt. This example uses touch pads connected to GPIO32, GPIO33 in ESP32 or GPIO9 in ESP32-S2 to trigger a wake up when any of the pads are pressed.
|
||||
4. **ULP:** Ultra Low Power Coprocessor which can continue to run during deep sleep. This example utilizes the ULP and constantly sample the chip's temperature and trigger a wake up if the chips temperature exceeds ~5 degrees Celsius.
|
||||
|
||||
Note: Some wake up sources can be disabled via configuration (see section on [project configuration](#Configure-the-project))

This example should be able to run on any commonly available ESP32 development board without any extra hardware if only **Timer** and **ULP** wake up sources are used. However, the following extra connections will be required for the remaining wake up sources.
|
||||
|
||||
- **EXT1:** GPIO25 and GPIO26 should be connected to LOW to avoid floating pins. When triggering a wake up, connect one or both of then pins to HIGH. Note that floating pins may trigger an wake up.
|
||||
- **EXT1:** GPIO2 and GPIO4 should be connected to LOW to avoid floating pins. When triggering a wake up, connect one or both of then pins to HIGH. Note that floating pins may trigger an wake up.
|
||||
|
||||
- **Touch:** GPIO32 and GPIO33 should be connected to touch sensors (see [Touch Sensor Application Note](https://github.com/espressif/esp-iot-solution/blob/master/documents/touch_pad_solution/touch_sensor_design_en.md)).
|
