| "DFRobot SEN0161-V2 Gravity: Analog pH Sensor/Meter Kit V2" |
| "DFRobot Gravity Expansion Shield and Sensors for Arduino - DFRobot SEN0161-V2, The pH is a value that represents the acidity or alkalinity of a solution. It is also called the hydrogen ion concentration index. The pH is a scale of hydrogen ion activity in a solution. pH has a wide range of uses in medicine, chemistry, and agriculture. Usually, the pH is a number between 0 to 14. Under the thermodynamic standard conditions, pH=7, which means the solution is neutral; a pH<7 means the solution is acidic; a pH>7 means the solution is alkaline.The DFRobot Gravity: Analog pH meter V2 is specifically designed to measure the pH of a solution and reflect the acidity or alkalinity. It is commonly used in various applications such as aquaponics, aquaculture and environmental water testing.As an upgraded version of pH meter V1, this product greatly improves the precision and user experience. The on-board voltage regulator chip supports the wide voltage supply of 3.3 to 5.5V, which is compatible with 5V and 3.3V main control boards. The output signal filtered by hardware has low jitter. The software library adopts the two-point calibration method, and can automatically identify two standard buffer solutions (4.0 and 7.0), making it simple and convenient.With this product, main control board (such as Arduino) and the software library, you can quickly build a pH meter, plug and play, with no soldering.

| "HQ Prop 5040 Tri-Blade Bullnose Propellers - Sets of 4 - HQ Prop 1433348, A 4-piece set of green-coloured 3-blade bull-nose propellers.3-blade propellers are less efficient than 2-bladed versions but have a greater surface area which means more thrust. Because of this, they are idea for racing where 'grip' in the air is important.The range of other colours available means that you can use them to quickly identify a drone in flight, mix and match so you can easily tell the front from the back when flying line of sight, or just generally look that little bit racier!
