+- D: id, 8 bit
+- B: where B is the battery status: 1=OK, 0=LOW, 1 bit
+- 0: just zero :)
+- N: NN is the channel: 00=CH1, 01=CH2, 11=CH3, 2bit
+- T: temperature, 12 bit: 2's complement, scaled by 10
+- C: 4 bit: seems to be 0xf constantly, a separator between temp and humidity
+- H: humidity sensor, humidity is 8 bits
+
+ * The sensor sends 37 bits 10 times,
+ * the packets are ppm modulated (distance coding) with a pulse of ~500 us
+ * followed by a short gap of ~1000 us for a 0 bit or a long ~2000 us gap for a
+ * 1 bit, the sync gap is ~4000 us.
