Wifi vs bluetooth arduino Bluetooth#
This technique enables the signal to be transmitted at a lower power per frequency and also allows multiple devices to use the same Wi-Fi transmitter. Initially developed in the 1990s, Wi-Fi has undergone several standardization processes, approved by the Institute of Electrical and Electronics Engineers (IEEE), to allow for greater bandwidth in data transfer.Īlthough both are wireless forms of communication, Bluetooth and Wi-Fi differ in terms of their purpose, capabilities, and other factors. Wi-Fi works by breaking a signal into pieces and transmitting those fragments over multiple radio frequencies. Wi-Fi is similar to Bluetooth in that it also uses radio waves for high-speed data transfer over short distances without the need for a wire connection. As a result, Bluetooth eliminates the need not only for a wire connection but also for maintaining a clear line of sight to communicate between devices. Bluetooth works by using radio frequencies, rather than the infrared spectrum used by traditional remote controls. But what exactly are Bluetooth and Wi-Fi, and how do they differ?īluetooth, developed in the late 1990s, is a technology designed to enable short-range wireless communication between electronic devices, such as between a laptop and a smartphone or between a computer and a television. If you have a smartphone, laptop, tablet, or similar device, it is probably equipped with both Bluetooth and Wi-Fi wireless capabilities.

I mean I guess if you'd get a 3 port network switch with PoE support for every sensor, you could get away with running dedicated cables, but that would be very expensive. You'll have to run one cable for each Arduino though.

This PoE splitter for instance would allow allow you to easily extract 5V form the cable: IEEE 802.3af Micro USB Active PoE Splitter Power over Ethernet 48V to 5V 2.4A for tablet Dropcam or Raspberry Pi|Transmission & Cables| - AliExpressĪnd I guess this could be used to send and receive data: ENC28J60 Ethernet LAN Network Mini 51/AVR/ARM/PIC Code For Arduino SPI Port Module|mini mini|arduino minimini enc28j60 - AliExpress
Or you could try to figure out a cheaper way.

PoE injectors that could take an input of 12V or 24V from your car are really cheap: POE Adapter cable RJ45 Injector Splitter Kit Tape Screened Passive Power Over Ethernet12 48v Synthesizer Separator Combiner|Transmission & Cables| - AliExpressĪnd then you could try to use a bunch of Arduinos with a shield supporting PoE like this one: Ethernet Shield W5100 R3 Support PoE For Arduino for UNO Mega 2560 Nano Free Shipping|ethernet shield|poe poepoe ethernet - AliExpress Maybe it would be a good idea to simply use PoE. I think instead of soldering to the wires directly I'd just buy a rj45 jack and solder to that: 10Pcs/set RJ45 Network Ethernet 8P 8C Female Socket Connectors 8Pin PCB Mount RJ45 8P8C Single Network Port|connector 8pin|mount connectorconnector rj45 - AliExpress I think that's why PoE operates at around 48V. Take into consideration that you may have to deal with massive voltage drops.
