ph sensor operated at 5v and also contain temperature sensor
This 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.
