/**
   ESP32 + DHT22 Example for Wokwi
   
   https://wokwi.com/arduino/projects/322410731508073042
*/
/*
  example uses ESP32, but should be easily adapted to Arduino or Raspberry Pico
  all of these should be low-cost and available
  
  TEMPERATURE:
    DHT22 is low-cost, resilient and widely available.
    It is digital, but should be accurate to several hundredths of degrees and can be polled at least every few seconds
  
  VIBRATION
    PIR motion sensor is assumed to be accurate enough for vibration data
    Gyro sensor is assumed to be used if more accurate than PIR motion sensor and can be used for greater accuracy
    SW-420 vibration sensor can be used as an alternate, assuming greater accuracy, but is not available in this simulator
  
  COMMUNICATION
    Modem is being used for this simulation with the intent of replacing or adapting that section of the code for other methods
  
  RTC
    This is used for timing, but can be eliminated for costs, assuming timing to be done at the network gateway level
