I want to connect an anemometer to my Raspberry Pi 3. I'm trying to use the Maplin N25FR Wind Speed Sensor.

How do I connect it to my Raspberry Pi?

I found this picture online, but I don't understand how it's connected and what device is being used to connect it. enter image description here

    You may be better off searching for Raspberry Pi plus the sensor you are interested in. Such hits are likely to find a sensor and how to interface that model of sensor to the Raspberry Pi. – joan Jan 5 '18 at 12:45
  • Thanks for your suggestion, but i would prefer using the maplin anemometer. – Haziq Muhammad Jan 5 '18 at 14:11

I believe the item you have circled is a GPIO extender which just makes connection to the GPIO pins on the Raspberry Pi a lot simpler. There are lots of different types available and it is even possible that the one in the image is home-made.

  • Thanks for your help. Could you please suggest a GPIO extender similar to the one he's using that i might be able to use. FYI the wire of the sensor is a RJ11. – Haziq Muhammad Jan 6 '18 at 12:38
  • I'm not aware of any thing on the market that will accept RJ11 and connect direct to GPIO. It looks as if someone else is doing a similar project at raspberrypi.org/forums/viewtopic.php?f=63&t=116308 You may find something of help there. – Mike Worsley Jan 26 '18 at 7:07
