particle-dht22

Use a DHT22 temperature & humidity module w/ Particle Argon/Xenon/Boron

Yes, this again.

Particle Cloud Functions

• enable() - Turns reading from module "on"
• disable() - Turns reading from module "off"
• enableDeepSleep() - Enables sleep, but not actually "deep" sleep
• disableDeepSleep() - Enables sleep, but not actually "deep" sleep
• setDelay(short) - Set update delay in ms

Note: Particle Cloud Functions accept a single String value; this code coerces any args into the proper data type.

Particle Cloud Variables

• settings - {String}: All settings in a JSON object. Properties:
  • enabled - {bool} (default true): Enabled or not
  • deepSleep - {bool} (default false): Deep sleep enabled or not
  • delay - {short} (default 900000; 15 minutes): Delay between reads in milliseconds

Notes

• This code persists settings in EEPROM. Should I be doing this? I have no idea.
• Going to try to hook this up to a LiPo battery
• Might add a INA219 to check battery and/or an RTC module to do actual deep sleep.
• The enclosure for this project will probably be clingfilm.
