DFRobot Gravity: Analog pH Sensor/Meter Kit V2

Introduction
The new Arduino Analog pH sensor/Meter is compatible with Raspberry Pi and Arduino microcontroller.

Attention：
1. The BNC connector and the signal conversion board must be kept dry and clean, otherwise, it will affect the input impedance, resulting in an inaccurate measurement. If it is damp, it needs to be dried.
2. The signal conversion board cannot be directly placed on a wet or semiconductor surface, otherwise, it will affect the input impedance, resulting in the inaccurate measurement. It is recommended to use the nylon pillar to fix the signal conversion board, allow a certain distance between the signal conversion board and the surface.

Features
3.3~5.5V wide voltage input
Hardware filtered output signal, low jitter
Gravity connector and BNC connector, plug and play, no welding
Software library supports two-point calibration, and automatically identifies standard buffer solution
Uniform size and connector, convenient for the design of mechanical structures
