1. What is pH sensor used for?
A pH sensor is a type of device used to measure and monitor the acidity or alkalinity in liquids. It has many applications, including water analysis, wastewater treatment, swimming pools maintenance and food production quality control. The sensors are typically inserted into liquid media for direct point-measurement readings; they can also be connected remotely via cables or Wi-Fi signals for continuous monitoring without physical contact with the medium being tested. With its high accuracy measurements across wide ranges of temperature levels and dynamic response times, it is an extremely useful tool that ensures exact readings regardless of environmental conditions. Ideal for both industrial and commercial use alike – from agriculture research projects to retail outlets such as restaurants - the versatile nature of today's pH sensing devices makes them essential assets within multiple industries worldwide.
2. How to calibrate the pH sensor?
The pH sensor can be calibrated by shorting the Vin and GND terminals at the probe side, thereby emulating a signal of pH 7. The onboard potentiometer near the BMC probe connector can then be adjusted to give an output of 2.5V between the Po and GND pin. Alternatively, you can also use analogRead() on the Arduino to calibrate it to 2.5V. For detailed instructions, please check out our pH sensor blog linked below.
3. Is a pH sensor input or output?
A pH sensor is an input device used to measure the hydrogen-ion activity in a solution. It measures and records changes in acidity or alkalinity of samples, such as water and soil. The measurement results are outputted digitally for further analysis from computers, PLCs (Programmable Logic Controllers), SCADA systems (Supervisory Control And Data Acquisition) and other equipment that require accurate data on environmental conditions. This reliable sensing technology ensures accuracy across different environments when recording liquid levels with minimal error margin—a crucial factor for quality control applications like medicine production lines or laboratory testing procedures. In short, this versatile tool can be applied anywhere where monitoring of solutions’ pH values is needed: it efficiently inputs received information without compromising its precision while providing efficient outputs when required by digital devices to drive decision-making processes accurately!
