DFRobot SEN0161 Gravity: Analog PH Sensor / Meter Kit For Arduino

Product Description

DFRobot Gravity Expansion Shield & Sensors for Arduino
- DFRobot SEN0161, What is p H? 'p H' stands for 'power of hydrogen', which is a measurement of hydrogen ion concentration. The p H scale ranges from 1 to 14, with 7 considered to be neutral. A p H less than 7 is said to be acidic & solutions with a p H greater than 7 are basic or alkaline. Need to measure water quality & other parameters but haven't got a low cost p H meter? The DFRobot analogue p H meter, has been specially designed for Arduino controllers & has convenient & practical ' Gravity' connector plus a host of useful features. It offers instant connection to your probe & your Arduino to get p H measurements at ± 0.1p H accuracy at 25&8451;. For most hobbyist this is a great accuracy range & it's low cost makes it a great tool for bio-robotics & other projects! The sensor has an LED which works as the power indicator, a BNC connector & PH2.0 sensor interface. To use it, simply connect the p H sensor with BNC connector, & plug the PH2.0 interface into the analogue input port of any Arduino controller. The sensor comes in a compact plastic box with foam for better mobile storage. Build your own p H meter gadget, or a water monitoring station for your water tanks. Use it for your aquaponics or fish tanks or other materials that need accurate p H measurements. DFRobot SEN0161 Gravity: Analog p H Sensor / Meter Kit For Arduino
