Need an ORP sensor? We compare entry-level Arduino meters, 24/7 online probes, and IP68 industrial RS485 sensors to help you build the best water IoT system.

DFRobot provides pH sensors for Arduino hobbyists to industrial use. Explore our detailed comparison to find the perfect sensor for your needs.

DFRobot offers both lab grade and industrial grade liquid sensors.such as PH sensor & EC sensor & DO sensor & ORP sensor

This project details the design and implementation of a novel aquatic robot that uses an autonomous surface vehicle (ASV) and a towed underwater glider (AUV) to capture water quality measurements at multiple depths across a body of water and display those measurements to an onshore user in real-time.

How to make a Aquarium Water Cooling System

A few people at Public Lab have expressed interest in the DFRobot TDS sensor for Arduino data loggers. This sensor measures the electrical conductivity of water and the analog result can be converted to an estimate of total dissolved solids (TDS).

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.

This simple system detects water quality through simulation Gravity: Analog pH Sensor / Meter Kit For Arduino and Gravity: Analog Turbidity Sensor For Arduino, and supplies and drains water through the submerged pump and solenoid valve.
