#Changelog#
##Version 0.15 (Development)##
- Improve / Fix debugging.
- Fix #16 so peering with HM-CC-RT-DN should stable now.
- Add hysteresis for battery voltage measurement.
- Experimental support for US-100 ultrasonic distance sensor (Do not use this experimental feature if you need the peering with HM-CC-RT-DN at this time)
##Version 0.14##
- Fix millis() overflow bug. Now, the sensor stays in sleep mode after 49 days, so battery should not drained anymore
- Battery voltage now measured with 1 digit only.
##Version 0.13 (Beta)##
- Add new register:
- transmitTryMax: How often should the sensor try to send data without ack.
- lowBatLimit: Defined the battery voltage used for low battery detection.
- ledMode: Switch the device LED on or off while sent out data.
- altitude: Define the sensor-altitude for calculating the air pressure at sea level.
