characters or phrases. Statistical models can be used to generate code for specific characters or phrases. Based on the frequency of their appearance, you can configure the shortest code for the most commonly used data. These technologies include entropy encoding, run-length encoding, and dictionary compression.

started, theoretically SR04 can reach 10 meters, the actual most nominal is four five meters, but the actual use of the environmental impact, Bo Master now hand SR04 is only three meters within the more accurate, three meters above the range can not be measured. SR04 have four pins, VCC, GND (or symbols like 〨), Echo, Trig. VCC can generally connect 3.3v-5v power, GND grounding is the negative, you can directly connect the Arduino on the 5V and GND pin power supply. Trig is the starting signal
