Soil is an important natural resource, just as the air and water that surround us are. Unfortunately it has been overlooked in the past and taken for granted with disastrous results, such as the North American dust bowl of the s. Today, the role of soil health on our climate as a whole is taken more seriously, with researchers at organizations such as the USDA-ARS US Department of Agriculture, Agricultural Research Service looking into how exactly soil interacts with the rest of our environment.
Because of ongoing research and general interest in soil health and sustainability growing every year, monitoring soil in a more substantial and quantifiable way is becoming more important. Monitoring soil in the past meant going out and physically handling the soil, taking samples, and comparing what was found to existing knowledge banks of soil information. Soil probes are now extremely accurate and offer an unparalleled look at what is going on below the surface.Arduino Soil Moisture Sensor Relay Control
They give instantaneous information on soil moisture content, salinity, temperature, and more. Soil sensors are an important tool for anyone involved with soil, from a small-town farmer trying to increase his crop yield to researchers looking at how soil retains and releases CO2.
More importantly, just as computers have increased in power and dropped in price due to economies of scale, advanced soil measurement systems can be found at prices that are affordable for everyone.
These sensors can be portable and used for instant measurements or installed for long-term monitoring. No commercially available soil moisture sensors measure water directly. Instead, they measure changes in some other soil property that is related to water content in a predictable way. The other soil property becomes a proxy for water content. Common soil properties that change in relation to water content and are easy to measure include dielectric permittivity and matric potential.
Sensors that measure dielectric permittivity are the most common type of soil moisture sensor. Regardless of the technology used in a sensor, the same principle applies: the bulk dielectric permittivity of soil changes with volumetric water content.
A simple way to think of permittivity is as stored electrical energy. The sensor generates an electric field in the soil. Because water molecules are polar, unbound water molecules in the soil rotate to line up with the electric field lines. The rotation of unbound water molecules requires energy—stored as potential energy in the aligned water molecules. More water in the soil stores more energy, and the higher the bulk permittivity of the soil will be.
In order for any soil probe to work, no matter the type, it must make contact with the soil. The greatest accuracy will be obtained when the soil probe is fully surrounded by the soil, with no gaps or air holes between the probe and the soil. The probe then sends electrical signals into the soil, measures the responses, and relays this information to a data logger or directly to the cloud with an Internet-connected wireless network.

Just insert the sensor in the soil and it can can measure moisture or water level content in it. It gives a digital output of 5V when moisture level is high and 0V when the moisture level is low in the soil. The sensor includes a potentiometer to set the desired moisture threshold. When the sensor measures more moisture than the set threshold, the digital output goes high and an LED indicates the output.
When the moisture in the soil is less thatn the set threshold, the output remains low. The digital output can be connected to a micro controller to sense the moisture level. The sensor also outputs an analog output which can be connected to the ADC of a micro controller to get the exact moisture level in the soild.
This sensor is great for making water gardening projects, water sensing, etc. We are available on Email only for all your queries. Register Login Checkout. Menu Special Pre-Book Deals.

Build me an NPK Sensor
NPK sensor. Hello guys, can anyone tell me how to make my own NPK sensor. I want to know what electronic and chemical combination helps me to make a stand alone device that can used to measure the NPK values and fed it into a micro-controller. Re: NPK sensor. This has been covered before here I think - I believe the consensus is there is not such thing as a small cheap NPK sensor, you need to do chemistry to get decent results.
Thanks for your reply, Sir. Well start by describing the chemical process and start trying to figure out how to automate it. It isn't enough just to want a thing to exist. Try making one. It isn't going to be easy.
It definitely won't be cheap. Keep Arduino stuff out on the boards where it belongs. I wonder if those things even exist - at any price. As these elements can appear in various different mineral forms, it's not easy to detect the NPK amounts.
N comes in nitrate, nitrite, urea, ammonium, and probably more forms including protein. P in the form of phosphates, and all kinds of chemical compounds found in plant matter.
K is the easy one, that's just the element.
Mass spectroscopy comes to mind to get to the actual amounts of the different elements present, but in that case you must make sure you do not get any rock minerals sand in your samples, as the K in there is not accessible to the plants. Good luck automating this. Usually if something that's potentially very useful doesn't exist, there's a good reason for that. Quality of answers is related to the quality of questions.
Good questions will get good answers. Useless answers are a sign of a poor question. Mass spec wouldn't break them all down. Not really what you'd want here.Get the most detailed soil quality data available, via a single probe with 26 sensors reporting soil moisture, salinity, and NPK at three different depths, as well as aeration, respiration, air temperature, light, and humidity.

Knowledge of the actual content of nitrogen, phosphorus, and potassium NPK in animal slurry is highly important to optimize crop production and avoid environmental pollution when slurry is spread on agricultural fields.
Here, we present a mobile, low-field nuclear magnetic resonance NMR sensor suitable for online monitoring of the NPK content in animal slurry as an alternative to crude estimates or tedious nonspecific, off-site laboratory analysis.
In correlation studies, the obtained NMR measurements show good agreement with reference measurements from commercial laboratories. Additional information as noted in text.
