pH Sensor: Assembling, Coding, & Calibrating with Arduino | Smart Gardening

In this video, I talk about what pH sensors are, why I’m using them for my aquaponics system, and how you can assemble, code, and calibrate the Gravity: Analog pH Sensor (Version 2) from DFROBOT. In addition to all of this, I also go over some small issues I encountered (incorrect calibration commands and trash data in the Serial Plotter) and provide easy solutions in case you experience them as well. This video can be watched/followed along as a step-by-step tutorial and is a part of my Smart Gardening series. ━ LINKS ━ DFROBOT “Gravity: Analog pH Sensor V2”: https://www.dfrobot.com/product-1782.html UNO R3 Controller Board: https://www.amazon.com/ELEGOO-Board-ATmega328P-ATMEGA16U2-Compliant/dp/B01EWOE0UU/ref=sr_1_6?dchild=1&keywords=uno+r3+controller+board&qid=1597208396&sr=8-6 Breadboard & Jumper Wires: https://www.amazon.com/Paxcoo-Breadboards-Arduino-Circboard-Prototyping/dp/B0727X6N9D/ref=as_li_ss_tl?crid=1C88WXAXVELGB&keywords=breadboard+and+wire+kit&qid=1557668156&s=gateway&sprefix=breadboard+and+wire,aps,146&sr=8-5&linkCode=sl1&tag=murraynet-20&linkId=e2412b8c03fd00de5c21ed841e3c88c3&language=en_US Download Arduino: https://www.arduino.cc/en/main/software DFROBOT Product Wiki (reference image, DFROBOT_PH-library, sample code, etc.): https://wiki.dfrobot.com/Gravity__Analog_pH_Sensor_Meter_Kit_V2_SKU_SEN0161-V2 ━ TIMESTAMPS ━ ►0:13 a quick intro to ph testers ►1:13 materials ►2:39 ph sensor set-up ►4:07 creating the program ►7:40 two small issues ━ CHANNEL INFO ━ Hello, everyone!
