DFRobot Gravity analogue pH Sensor Meter Kit V2

This V2 analogue pH meter is specially designed to measure the pH of solutions and water and reflect the acidity or alkalinity level. It is widely used in various applications such as aquariums, aquaponics, aquaculture and environmental water testing. As an improved version of the V1 pH meter, this product greatly improves precision and ease of use. The built-in voltage regulator chip supports the operating voltage from 3.3 to 5.5V, which is compatible with the 5V and 3.3V microcontroller. The output signal filtered by the hardware has low jitter. The software library uses the two-point calibration method and can automatically identify two standard buffer solutions (4.0 and 7.0). With this product and an Arduino with the appropriate software library, you can quickly build a pH meter to measure the pH of your aquarium, for example.
