# Power saving mode # Power saving mode
Paxcounter supports a battery friendly power saving mode. In this mode the device enters deep sleep, after all data is polled from all sensors and the dataset is completeley sent through all user configured channels (LORAWAN / SPI / MQTT). Set *#define SLEEPCYCLE* in paxcounter.conf to enable power saving mode and to specify the duration of a sleep cycle. Power consumption in deep sleep mode depends on your hardware, i.e. if on board peripherals can be switched off or set to a chip specific sleep mode either by MCU or by power management unit (PMU) as found on TTGO T-BEAM v1.0/V1.1. See *power.cpp* for power management, and *reset.cpp* for sleep and wakeup logic. Paxcounter supports a battery friendly power saving mode.

# Covid-19 Exposure Notification System beacon detection (currently NOT working with v3.0.x, use v2.4.x for this feature)
Bluetooth low energy service UUID 0xFD6F, used by Google/Apple COVID-19 Exposure Notification System, can be monitored and counted. By comparing with the total number of observed devices this <A HREF="https://linux-fuer-wi.blogspot.com/2020/10/suche-die-zahl-64879.html">gives an indication</A> how many people staying in proximity are using Apps for tracing COVID-19 exposures, e.g. in Germany the "Corona Warn App". To achive best results with this funcion, use following settings in `paxcounter.conf`:
#define COUNT_ENS 1 // enable ENS monitoring function
#define BLECOUNTER 1 // enable bluetooth sniffing
#define WIFICOUNTER 0 // disable wifi sniffing (improves BLE scan speed)
#define HAS_SENSOR_1 1 // optional, in board's hal file: transmit ENS counter data to server
# SD-card # SD-card
Data can be stored on an SD-card if one is availabe. Simply choose the file in src/hal and add the following lines to your hal-file: Data can be stored on SD-card if the board provides an SD card interface, either with SPI or MMC mode. To enable this feature, specify interface mode and hardware pins in board's hal file (src/hal/<board.h>):

Please correct the numbers given in the example to the numbers used corresponding to your wiring. In this case you choose the correct file for your ESP32-board in the src/hal-directory and add the lines given above. Edit the pin numbers given in the example, according to your wiring.
Some hints: Data is written on SD-card to a single file. After 3 write operations the data is flushed to the disk to minimize flash write cycles. Thus, up to the last 3 records of data will get lost when the PAXCOUNTER looses power during operation.
These cheap devices often handle SD-cards up to 32GB, not bigger ones. They can handle files in the old DOS-way, to say the filenames are in the 8.3-format. And they often cannot handle subdirectories.
The software included here writes data in a file named PAXCOUNT.xx, where xx can range from 00 to 99. The software starts with 00, checks to see if such a file already exists and if yes it will continue with the next number (up to 99 - in this case it will return no sd-card). So an existing file will not be overwritten. Format of the resulting file is CSV, thus easy import in LibreOffice, Excel, Influx, etc. Each record contains timestamp (in ISO8601 format), paxcount (wifi and ble) and battery voltage (optional). Voltage is logged if the device has a battery voltage sensor (to be configured in board hal file).
The data is written to the card and after 3 write-operations the data is flushed to the disk. So maybe the last 3 minutes of data get lost when you disconnect the PAXCOUNTER from power. File contents example:
And finally: this is the data written to the disk: timestamp,wifi,ble[,voltage]
