A conductivity sensor is an analytical instrument designed to precisely measure the ability of a solution to conduct an electric current. This conductivity is directly proportional to the concentration of ions present, serving as a reliable indicator of total dissolved solids (TDS), sample purity, and chemical composition.

The calibration of conductivity sensor is the key operation to ensure the measurement accuracy. Its core is to correct the measurement deviation of the sensor through the standard solution of known conductivity. The following are common calibration steps, which are suitable for laboratory and industrial online sensors.

With the advancement of sensing technology, different types of rain gauges have emerged, with tipping bucket and piezoelectric designs being particularly common. Tipping bucket rain gauges, due to their stable mechanical structure and easy maintenance, have long been widely used in traditional weather stations. Piezoelectric sensors, on the other hand, are gradually gaining prominence in intelligent monitoring systems due to their high dynamic response and anti-interference capabilities. However, the trade-offs between these two technologies in practical applications, including accuracy, environmental adaptability, and cost, require further exploration. This article will compare these technologies from multiple perspectives, including their principles, advantages and disadvantages, and applicable scenarios, to help users select the optimal solution based on their specific needs.

From the water we drink to the oceans we cherish, from life-saving drug production to smart agricultural irrigation—our ability to safeguard and optimize these processes hinges on one essential measurement: conductivity. Often unseen yet indispensable, the conductivity sensor operates as a silent guardian, providing critical data that keeps industries running and ecosystems protected.

The accuracy of rain sensor data is highly dependent on proper installation. This article aims to provide a complete guide from site selection and installation to calibration to ensure your sensor performs optimally.

Air quality sensors are important devices for monitoring pollutants such as PM2.5, PM10, VOCs, and CO₂ in the environment.
