Overview
Analog pH Sensor / Meter Kit specially designed for Arduino controllers and has convenient and practical "Gravity" connector and a bunch of features. Instant connection to your probe an your Arduino to get pH measurements at ± 0.1pH (25 ℃). For most hobbyist this great accuracy range and it's low cost makes this a great tool for biorobotics and other projects! It has an LED which works as the Power Indicator, a BNC connector and pH2.0 sensor interface. To use it, just connect the pH sensor with BND connector, and plug the pH2.0 interface into the analog input port of any Arduino controller. If pre-programmed, you will get the pH value easily. Comes in compact plastic box with foams for better mobile storage.
Build your own pH meter gadget, or a water monitoring station for your water tanks. It could make for the ultimate water control device. Use it for your aquaponics or fish tanks or other materials that need measurements.

If you need a device which draws a certain amount of current and power for testing, then GreatScott! has just the solution. His project uses an Arduino Nano, along with a separate IC and a voltage divider, to measure both current and voltage input from the power source. It then employs this data to properly adjust a MOSFET, dissipating the correct amount of voltage and power as required. Interface is handled via a rotary encoder and a 16x2 I2C LCD display, and the electronics are housed in a solid-looking enclosure. As seen in the video below, the adjustable constant load features an impressively large heat sink, needed to take care of the 30V and 20A that the setup is capable of drawing.
