Water color is measured either via standardized lab tests using the Platinum-Cobalt (Pt-Co/APHA) scale and spectrophotometry for regulatory compliance, or through continuous digital sensing (RGB, CIE, LUX) for real-time trend monitoring and event detection. Water color looks like the simplest parameter in the water quality toolkit. Anyone can glance into a tank, a reservoir, or […]

Color sensors are used to measure and quantify color with a precision the human eye simply cannot match. They play a critical role in water quality monitoring, hydroponic nutrient management, industrial sorting, product quality control, and aquaculture, converting reflected or transmitted light into objective RGB, CIE, and LUX data that drives automated decisions. Most conversations

Industrial pH monitoring sounds simple: connect a pH probe, measure the process, and send the reading to a PLC or control system. In practice, choosing the right transmitter can become complicated quickly. Some industrial pH transmitters are sophisticated multiparameter analyzers with digital communications, relays, PID control, data logging, and proprietary sensor ecosystems. Those capabilities can

The 4-20mA current loop is the dominant analog signaling method in industrial process control. It transmits sensor measurements, such as temperature, pressure, pH, and flow, as a varying electrical current between 4 and 20 milliamps. Because it uses current rather than voltage, it is highly resistant to electrical noise, works reliably over long cable runs,

An oxygen sensor is a device that measures the concentration of oxygen, either dissolved in water or present in gas. It converts the measurement into a readable electrical signal.  Oxygen sensors are used across a wide range of industries, from aquaculture and hydroponics to wastewater management and environmental monitoring. Without accurate oxygen sensing, it becomes

Conductivity is one of the most important measurements in industrial water systems. From water treatment and hydroponics to chemical processing and manufacturing, conductivity provides a fast and reliable indication of the concentration of dissolved ionic material in a solution. But measuring conductivity is only part of the challenge. In an industrial environment, the measurement needs

When a process requires more than one chemical, nutrient, reagent, or additive, using several independent dosing pumps can quickly become complicated. A multi-pump dosing system combines multiple dosing channels into a single platform, making it easier to automate fluid handling while reducing wiring, installation complexity, and equipment footprint. These systems are commonly used in hydroponics,

Dissolved oxygen is one of the most important measurements in water treatment, aquaculture, environmental monitoring, industrial processing, research, and many other applications. When a dissolved oxygen probe is expected to remain installed for months or years, however, measurement range is only part of the equation. An industrial dissolved oxygen probe must also withstand pressure, temperature

Indoor air quality can have a major impact on the comfort and productivity of homes, offices, schools, laboratories, and industrial facilities. Carbon dioxide buildup, poor ventilation, temperature fluctuations, and improper humidity levels can all indicate that an indoor environment needs attention. That has led to a rapidly growing selection of indoor air quality monitors. Some

UART and I2C are serial communication protocols, but they serve different purposes. UART is typically used for direct device-to-device communication and requires dedicated connections. I2C uses just two shared wires, allowing multiple sensors and peripherals to communicate with a single microcontroller on the same bus. UART and I2C are some of the most common communication
