A particulate matter sensor is a device used to detect and measure the concentration of suspended particulate matter (e.g. PM2.5 and PM10) in the air. These particles include both solid and liquid particles and can be divided into different categories based on particle size, such as PM2.5 (particles less than or equal to 2.5 microns in diameter) and PM10 (particles less than or equal to 10 microns···

A soil moisture sensor, or soil moisture sensor, soil moisture sensor, soil moisture content sensor, is a device designed to measure the moisture content of soil. These sensors have a wide range of applications in various fields such as agricultural irrigation, forestry conservation, environmental monitoring and scientific research. Below is an overview of soil moisture sensors, including their wo···

Irrigation sensors provide data support for irrigation systems by sensing farmland environmental parameters (e.g., soil moisture, temperature, rainfall, etc.) and converting them into electrical signals. Irrigation sensors, as a core component of irrigation systems, provide strong support for precision and water-saving irrigation by monitoring various environmental parameters in farmland in real t···

In irrigation water management, selecting a suitable soil moisture sensor (such as TDR or FDR) and installing it correctly, connecting it to a data acquisition system, monitoring and analyzing soil moisture data in real time, formulating an irrigation plan, and realizing automated irrigation.The TDR is highly accurate but costly, while the FDR is less costly and easy to install. Through the soil m···

Automated irrigation systems utilize sensors and control technology to achieve precision irrigation. Commonly used soil moisture sensors include capacitive, resistive, TDR, and FDR, and are selected with consideration of accuracy, stability, maintenance costs, system integration, and budget. These sensors are combined with other weather sensors to transmit data to a control unit for decision makin···

Smart irrigation systems utilize a variety of sensors, such as soil moisture, temperature, rainfall, weather, flow, pressure, EC conductivity, etc., to achieve precise monitoring and automatic control of irrigation. These sensors provide a scientific basis for irrigation decision-making, ensure the timeliness and effectiveness of irrigation, significantly improve irrigation efficiency, and save wa···

There are a variety of methods for testing soil moisture content, including drying, chemical, electrical, suction, ray, remote sensing, time-domain reflectance, frequency-domain reflectance, and soil moisture sensors, each with its own advantages and disadvantages. The choice needs to take into account specific needs and conditions, and care needs to be taken to maintain equipment accuracy and sta···

Soil moisture sensor is an important tool in modern agricultural technology, through different technical means to realize the accurate measurement of soil moisture. Choosing the right type of sensor is crucial for realizing efficient and water-saving irrigation management. They not only enhance agricultural productivity, but also promote environmental sustainability, are a bridge between technolog···

The unit of measurement for soil moisture sensors is usually volumetric water content, which is expressed as a percentage by volume (%V/V) or (m3). This means that the sensor measures the volume of water in the soil as a percentage of the total volume. For example, a soil moisture sensor with a measurement of 30% (m3) indicates that out of every cubic meter of soil, 0.3 cubic meters is water.

The use of sensors in irrigation systems has many advantages, which are not only reflected in the improvement of irrigation accuracy and water saving, but also in optimizing the growing environment of crops, improving the efficiency of agricultural production, preventing natural disasters, promoting the development of smart agriculture, and reducing the use of chemical fertilizers and pesticides. ···
