Monthly Giveaway April


Has anyone ever think about adding an odometer speedometer for your own bicycle? Just the same as this wish of robert. If so, Seeed would help you.  This month we decided to come up with this great tool for rotate speed detection- the Grove – Hall Sensor and a Grove-OLED to show the results.  As routine, we are giving 5 kits of these modules.

With the Hall sensor, and of course a magnet, you can detect the rotate speed of something, such as the bicycle. And with the OLED module to show the result, you can make a complete odometer &speedometer with an Arduino/Seeeduino.

There is another application that uses a Grove-reflective sensor to do the same work, but I think, a hall sensor would be easy to use in such applications .

From 11th to 15th of April, 2013
