Gravity: Analog TDS Sensor/ Meter for Arduino

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 six+ cool projects in this kit will give children new insights into artificial intelligence while they are entertained.

Note: the micro:bit board is not included, you can buy it separately.

Micro:bit Tinker Kit - Create a variety of octopus sensors thanks to the Tinker kit and the many project tutorials to help you create dozens of amazing digital maker projects. Note: the micro:bit board is not included, you can buy it separately. All modules have convenient connectors to use them and no soldering is required.

12VDC plastic solenoid valve. Normally closed. Liquid can flow in one direction and a minimum pressure of 0.02Mpa (3 PSI) is required. This liquid valve would be a great addition to your robotic gardening project. There are two 1/2 ″ outlets. Normally, the valve is closed. When 12VDC is applied to the two terminals, the valve can be opened and pushed.

With this 32 in 1 construction kit you can build all 32 options or develop your imagination by building your own project.

Note: the micro:bit board is not included, you can buy it separately.

ELECFREAKS Smart Science IoT Kit is developed on the basis of loT:Bit, a new breakout board compatible with ultrasonic sensor, dust sensor, light sensor and water level sensor, including RTC Timing and WIFI module. It can build the scene such as air quality monitoring, environmental noise detection, environmental quality monitoring station, automatic watering detection, self-defence monitoring station and more.

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.

DFRobot Gravity: The V2 analogue pH meter is specifically designed to measure the pH of the solution and reflect the acidity or alkalinity. The DFRobot ph sensor is commonly used in various applications such as aquaponics, aquaculture and environmental water testing.

The pH is a value that measures acidity or alkalinity.

Turn everything into a "keyboard" thanks to the Bitboard.

The RETRO Arcade for Education is the first large-screen arcade device with high resolution. Children can use it to fuel their creativity by easily creating their games while having fun playing.
