Bits 0-3: header Bits 4-11: device ID, changes when replacing the batteries. Unlike in the post linked above, bit 11 does not appear to be a checksum. Bits 12-15: either 1111 for automatic transmission (once every 60 seconds) or 1011 for manual transmission (using the button in the battery compartment). Manual transmission does not update the weather station. Bits 16-27: encode the temperature. The system of encoding decimal digits seems to be ditched in favor of a more elegant one: apply a NOT (change 1 to 0 and 0 to 1), convert to base 10, divide by 10 (into a float), subtract 50, and the result is the temperature in C. Bits 28-35: encode the relative humidity. Apply a NOT, convert to base 10, and the result is the relative humidity in %. Bits 36-43: appear to encode a checksum (though I plan to double-check if this is not the dew point, also reported by the weather station).
*HHHH 1000 0010 1111 1101 0010 1111 1101 0011 1010 0100 encoding T=22.0C and RH=44%

*How to connect multiple Sensors: The DS18B20 Digital Temperature sensor allows you to set multiple in parallel. When doing this, the OneWire library will read all sensors. For larger networks of sensors (more than 10), using smaller resistors should be considered, for example 1.6 KΩ or even less. It has been observed that large amounts of sensors (more than 10) in the same network can cause issues (colliding data), and for that purpose an additional resistor of say 100 … 120 Ω should be added between the data line to the Arduino and the data pin of the sensor, for each sensor !
