Here are some items you might be interested in for liquid sensors：
Project 1. Arduino Project: pH sensor Working, application & Calibration "Water Quality Monitoring"
Introduction: This tutorial is about how to use the pH sensor with Arduino and find the pH value of different liquids “Water, Milk and Cold rink”, and display the pH value on the serial monitor.
Project 2. Build KnowFlow: automatic water monitor
KnowFlow is the name of this water quality monitoring device, based on Arduino Uno. It can automatically monitor 5 parameters of water: pH, Temperature, Dissolved Oxygen, Electronic Conductivity, ORP.
Project 3. Analog Dissolved Oxygen Sensor Tutorial | DIY Arduino D.O. Meter
Introduction: Since measuring the parameter of water quality is a complex task, so measuring the dissolved oxygen in water is also not an easy task. That is why the Dissolved Oxygen Meter (DO Meter) available in the market is very expensive. That is why it is important to make your own Dissolved Oxygen Meter. So the Gravity Analog Dissolved Oxygen Sensor from DFRobot is one of the most popular and best Dissolved Oxygen Sensors that are available in the market.
