Soil Moisture Sensor

-

Soil moisture plays a key role in the life of the plant.  Nutrients in the soil solution provide the plant with the food it needs to grow.  Water is also essential for regulating plant temperature through the process of transpiration.  Plant root systems are better developed when growing in moist soil.  Excessive levels of soil moisture, however, can lead to anaerobic conditions that can promote the growth of plant and soil pathogens.

Soil moisture sensors measure the volumetric water content in soil.[1] Since the direct gravimetric measurement of free soil moisture requires removing, drying, and weighing of a sample, soil moisture sensors measure the volumetric water content indirectly by using some other property of the soil, such as electrical resistance, dielectric constant, or interaction with neutrons, as a proxy for the moisture content.

The relation between the measured property and soil moisture must be calibrated and may vary depending on environmental factors such as soil type, temperature, or electric conductivity. Reflected microwave radiation is affected by the soil moisture and is used for remote sensing in hydrology and agriculture. Portable probe instruments can be used by farmers or gardeners.

Soil moisture sensors typically refer to sensors that estimate volumetric water content. Another class of sensors measure another property of moisture in soils called water potential; these sensors are usually referred to as soil water potential sensors and include tensiometers and gypsum blocks.

  STMicro Unveils 6-axis IMU with Embedded Sensor Fusion and AI Among the most fundamental trends in the consumer electronics industry today is the proliferation of sensors . For applications such the Internet of Things (IoT), wearables, and AR/VR, sensing has been a core technology. As devices become embedded with more and more sensors , system developers face about how to best handle and fuse that data into a useful format. To address this issue,  STMicroelectronics (ST) has recently released  a new 6-axis IMU which includes a number of integrated features such as sensor fusion blocks and Machine Learning (ML) cores.   1st Editional of International Research Awards on Sensing Technology | 23-24 Jan 2023 | India Abstract Submission:  https://x-i.me/gaycon Award Nomination:  https://x-i.me/gaynom Member Nomination:  https://x-i.me/gaymem Visit:http://sensors-conferences.sciencefather.com/ For Enquiries: sensors@sciencefather.com

Temperature Sensors

  Temperature Sensors: A temperature sensor is an electronic device that measures the temperature of its environment and converts the input data into electronic data to record, monitor, or signal temperature changes. There are many different types of temperature sensors. Some temperature sensors require   direct contact   with the physical object that is being monitored (contact temperature sensors), while others indirectly measure the temperature of an object (non-contact temperature sensors).   Non-contact temperature sensors are usually infrared (IR) sensors. They remotely detect the IR energy emitted by an object and send a signal to a calibrated electronic circuit that determines the object's temperature. Among the contact temperature sensors are  thermocouples and thermistors . A thermocouple is comprised of two conductors, each made of a different type of metal, that  are joined at an end  to ...

  What are Sensors, Detectors, and Transducers? Sensor/Detectors/Transducers are electrical, opto-electrical , or electronic devices composed of specialty electronics or otherwise sensitive materials , for determining if there is a presence of a particular entity or function. Many types of sensors , detectors, and transducers are available including those for detecting a physical presence such as flame , metals , leaks , levels, or gas and chemicals , among others. Some are designed to sense physical properties such as temperature, pressure, or radiation , while others can detect motion or proximity . They operate in a variety of manners depending on the application and may include electromagnetic fields, or optics, among others. Many applications over a wide range of industries use sensors, detectors, and transducers of many kinds to test, measure, and control various processes and machine functions. With the advent of the  Internet of Things (IoT) , the need for sensors...
