+ * The MySensors Arduino library handles the wireless radio link and protocol
+ * between your home built sensors/actuators and HA controller of choice.
+ * The sensors forms a self healing radio network with optional repeaters. Each
+ * repeater and gateway builds a routing tables in EEPROM which keeps track of the
+ * network topology allowing messages to be routed to nodes.

+ * DESCRIPTION
+ *
+ *  MH-Z14 CO2 sensor
+ *
+ *  Wiring:
+ *   Pad 1, Pad 5: Vin (Voltage input 4.5V-6V)
+ *   Pad 2, Pad 3, Pad 12: GND
+ *   Pad 6: PWM output ==> pin 6
+ *
+ *	From: http://davidegironi.blogspot.fr/2014/01/co2-meter-using-ndir-infrared-mh-z14.html
+ * 	  MH-Z14 has a PWM output, with a sensitivity range of 0ppm to 2000ppm CO2, an accuracy of ±200ppm.
+ * 	  The cycle is 1004ms±5%, given the duty cicle Th (pulse high), Tl is 1004-Th, we can convert it to CO2 value using the formula:
+ *	  CO2ppm = 2000 * (Th - 2ms) /(Th + Tl - 4ms)
+ * 	From: http://airqualityegg.wikispaces.com/Sensor+Tests
+ *	  - response time is less than 30 s
+ *   - 3 minute warm up time
+ *	datasheet: http://www.futurlec.com/Datasheet/Sensor/MH-Z14.pdf
