Here we Discuss Important Tools which used in Measuring Soil Moisture data logger
our soil moisture data logger Design by Microcontroller based (ARM) with 16 channel available for sensors and these sensors are working with Channel for analog/Digital each and Display: 16*2 LCD Showing all data in real-time our 8 channel Analog Sensor Inputs are Showing like temp, humidity and another ph values in Soil
These 4 channel Digital Sensor Input is Some Memory Which used and stored SD Card (For Available in the selected module only) Here are some for Options: High rate/Low rate Channel Selection in our data logger. Interval log Basically Showing 600 samples/sec to 1sample/week And Timing: Build In Real Time Clock also Supply: AC operated/Battery Operated/DC Operated.
Our Company Datalogger Storage could be shown in In Ms. Excel Sheet, Each record are stored with Time &Date also Relay Interface Can be used to interface a +12V DC component. The Data Logging Real-Time with programmable log and storage time.
That’s why Soil moisture range from 0 to 35% VWC ,accuracy ± 2% also Soil Temperature -40degree to 85 degree Accuracy ± 0.5& Soil pH 0-14 accuracy 0.001
Reason Behind To Use Soil Moisture Data Logger
soil moisture content of soil is the quantity of water it contains. Water content is used in a wide range of scientific and technical areas and is expressed as a ratio, which can range from 0 (completely dry) to the value of the materials’ porosity at saturation.
Moisture may be present as adsorbed moisture at internal surfaces and as capillary condensed water in small pores. At low relative humidity’s, moisture consists mainly of adsorbed water. At higher relative humidity’s, liquid water becomes more and more important, depending on the pore size.
Now soil science, hydrology and agricultural sciences, water content has an important role for groundwater recharge, agriculture and soil chemistry. If the moisture content of a soil is optimum for plant growth, plants can readily absorb soil water. Not all the water, held in soil, is available to plants. Much of water remains in the soil as a thin film. Soil water dissolves salts and makes up the soil solution, which is important as medium for supply of nutrients to growing plants.
There are many facts that soils hold water (moisture) is due to their colloidal properties and aggregation qualities. The water is held on the surface of the colloids and other particles and in the pores. The forces responsible for retention of water in the soil after the drainage has stopped are due to surface tension and surface attraction and are called surface moisture tension. This refers to the energy concept in moisture retention relationships. The force with which water is held is also termed as suction.
