WEEK 8

For this week, the LoRa modules, SX1278 is purchased at shopee. The specification of the LoRa is been studied more, to determined either it is the suitable radio transmitter that will be used in this project. Below is the specification of the LoRa modules:

 Supply voltage = 3.3 V

 Temperature = 25° C

 fXOSC = 32 MHz

 bandwidth (BW) = 125 kHz

 Spreading Factor (SF) = 12

 Error Correction Code (EC) = 4/6

 Packet Error Rate (PER)= 1%

 CRC on payload enabled

 Output power = 13 dBm in transmission

 Payload length = 64 bytes

 Preamble Length = 12 symbols

By seeing and study the above specification, it can be conclude that, this LoRa  module is suitable to be used in this project.
