Abstract
The present research aims to enhance energy efficiency saved by implementing Huffman coding in the data obtained through the transmission of an ECG device and a receiver. The data is first compressed and later transmitted by a wireless module. The heartbeat signal is acquired through an ADC (ESP 32 module). The compressed data is scaled into 8 bits, followed by a package method using the Huffman coding. Posterior, the data is sent wirelessly from the transmitter module to the receiver. The beats per minute are calculated by using the received data. In the present method, compressed 400-byte packets and a continuous uncompressed 1-byte packet were tested under energy efficiency scope. One of the outcomes is that the saved energy was roughly 20%. Furthermore, the current consumption is analyzed under multiple package size transmission.

Keywords
Energy savings, Heart rate, Wireless transmission, Electrocardiogram (ECG).
