F50-12V 10W DC Micro Hydro Generator

The Arduino turbidity sensor SEN0189  detects water quality by measuring turbidity levels. It can detect suspended particles in water by measuring the light transmittance and the scattering coefficient, which changes with the amount of total suspended solids (TTS) in the water.

When using the HuskyLens, you may encounter accidental drops, bumps, etc. Now we have carefully designed this silicone case to protect your board.

Note: This product does not include the HuskyLens board.

The meter built on the basis of a water rotor and a Hall effect sensor

GamePad for micro:bit V4.0 adopts a high-precision three-axis analog quantity joystick. The combination of joystick and gamepad allows you to control the direction and speed of Maqueen at the same time. In addition, there are 7 programmable buttons, which means you can explore more interesting functions and more flexible controls. In the latest V4.0 product, we have placed the external battery box on the PCB, which is more convenient to use.

Six cases of fun in one kit: kids can build 6 shapes, including traffic lights, brick car, temperature-controlled fans, smart desk lamp, windscreen wiper and trebuchet.
