I am working on a project that involves sending motion sensing data wirelessly from an arduino to computer. Sensor readings have to be transmitted continuously (say every mili second). I am not sure if Xbee is my bet. I came across this link which suggest s that there should be atleast 10 ms delay between packets if you're using xbees.

What are your experiences with xbees? I don't want to waste money.

  • what is the distance between devices? – Martynas Jan 30 '15 at 12:11
  • Not more than 5 - 10 meters I think. – Ajit Jan 30 '15 at 12:13
  • if you don't want to waste money take bluetooth adapter. HC-06 is around 4$. Also there are NRF24L01+ 2.4GHz trasceivers. They are cheap and fast – Martynas Jan 30 '15 at 12:17
  • How much data do you need to transmit every millisecond? I like the nRF24l01+ units and have found them reliable at ranges around 10-15 metres but they have a max payload of 32 bytes and top speed of 2Mbps, both of which will limit throughput. – Roger Rowland Jan 30 '15 at 12:53
  • I can connect atmost six sensors to the arduino. So It should be around 20 bytes tops. What do you guys think about xbees? I know I can get those easily in my country. Not entirely sure about nRF24l01+. – Ajit Jan 30 '15 at 13:01

Xbee costs about 1000INR. They are really expensive. You should buy HC-05 module, which costs about 320INR. You can easily interface them with Bluetooth of your Laptop using Processing Application.

You can even use ESP8266 ESP-01 Wireless Module. They Cost about 3$. Wireless module gets connected with your router. this tutorial will help you to start. You can by this module from here.

nRF24l01+ modules can not be interfaced with Laptop...

  • Thanks a lot for the suggestion but I am specifically looking for a rf or wifi solution – Ajit Jan 31 '15 at 6:19
  • ESP8266 ESP-01 Wireless Module is a WiFi solution to your problem!! – AngryBird Jan 31 '15 at 11:02
