Sleep mode and autoclean for sensirion sps30

[roberbike]

For the sensirion sps30, add new functions to achieve the following improvements:

Sleep mode to save battery. 2 18650 1.5Abatteries , only can run for 6 hours aprox.

Autoclean activated for fixed stations. By default autoclean happens 1 time per week, but if the station is power off, the counter goes to 0. There is a function to make a clean on start up, in order to keep the sensor clean.

define PERFORMCLEANNOW 1

if (PERFORMCLEANNOW) { // clean now if (sps30.clean() == true) Serial.println (DEBUG("fan-cleaning manually started")); else Serial.println (DEBUG("Could NOT manually start fan-cleaning"));

I forgot mention, that during the autoclean periode, there is not particle measurement .

/ define new AUTO Clean interval Will be remembered after power off default is 604800 seconds

• 0 = disable Auto Clean
• -1 = do not change current setting
• */

define AUTOCLEANINTERVAL 1

/* Perform a clean NOW ?

• 1 = yes
• 0 = NO */

define PERFORMCLEANNOW 1

// do Auto Clean interval SetAutoClean();

// start measurement if (sps30.start() == true) Serial.println(F("Measurement started")); else Errorloop((char *) "Could NOT start measurement", 0);

// clean now requested if (PERFORMCLEANNOW) { // clean now if (sps30.clean() == true) Serial.println(F("fan-cleaning manually started")); else Serial.println(F("Could NOT manually start fan-cleaning"));

/**

  // try to get interval ret = sps30.GetAutoCleanInt(&interval); if (ret == ERR_OK) { Serial.print(F("Current Auto Clean interval: ")); Serial.print(interval); Serial.println(F(" seconds")); } else ErrtoMess((char *) "could not get clean interval.", ret);

void loop() {

uint8_t ret;

// read all ddata read_all();

Serial.println("Entering sleep-mode");

// put the SPS30 to sleep ret = sps30.sleep();

if (ret != ERR_OK) { ErrtoMess((char *) "ERROR: Could not set SPS30 to sleep. ", ret); }

// wait 10000mS = 10 sec delay(10000);

Serial.println("Perform wakeup");

// wakeup SPS30 ret = sps30.wakeup();

if (ret != ERR_OK) { ErrtoMess((char *) "ERROR: Could not wakeup SPS30. ", ret); }

// as the SPS30 was in measurement mode before sleep that is restored Serial.println("measurement mode");

// give time for new air to flow in delay(5000); }

I'm going to close this issue because is better handling the power management and consumption on firmware level
