Metal long standoffs: 1" long x ¼" OD. Used to get your proto board up off the table. #4-40 thread. Fits most development boards with available holes. Don’t forget the screws, found below.
Actobotics is a robotics building system based around extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to the two standardized hole patterns, nearly all Actobotics components can be intuitively connected together. The wide range of components makes building complex electromechanical prototypes or finished projects a reality.
The HIH6130 is a digital output-type relative humidity (RH) and temperature sensor combined in the same package. This allows the RH measurement to be temperature compensated and provides a second, standalone temperature sensor output.
