Development and Performance Evaluation of a Soil Moisture Sensor

This study was aimed at developing a soil moisture sensor to effectively monitor moisture level for optimum crop growth. The sensor was made using a programmed Arduino microcontroller. It is attached to a sensing panel with two probes made of nickel that measures the volumetric content of water in soil. The probes were non-corrosive and robust material suitable for use in wet surfaces. The developed sensor was tested and evaluated. The two legged Lead (probes) goes into the soil where water content was to be measured by passing current through the soil, and then reads the resistance to get the moisture level. Nine different soil classification samples (Sandy Clay, Fine Sandy Loam, Sandy Loam, Salty Loam, Loamy Sand, Coarse Sand, Fine Sand, Sandy Clay Loam and clay soils) at different depths (3, 6, 9, 12 and 14.3 cm) were used to analyse the moisture meter at three different portion of each soil sample. Results obtained indicates that there was a progressive increase in moisture levels the more the sensor was being dipped into the soil. Results obtained also shows that all the nine soil samples but one (Silt Loam Soil Sample) analysed were within acceptable range of accuracy (0.1 - 5.0 %). The moisture sensor whose cost was approximately #22,300:00 was found to be effective, high precision at less efforts and a suitable guide for farmer for determining soil moisture levels.Keywords- Moisture, Probe, Sensor, Soil Classification

Nowadays gardening has become a hobby for everyone. Everyone is showing interest in growing their own plants in their houses like terrace farming. So we have decided to do a project which can be useful for everyone even the farmers can be benefitted by our project. In our project we are preparing a greenhouse for cultivating different kinds of crops. Our greenhouse consists of arduino UNO, sensors like (temperature sensor, soil moisture sensor, colour sensor and light sensor), actuators. All these are used in sensing the outside environment and giving signals to arduino so that it sends the signal through GSM module and this GSM module will give us a message alert through our mobile phones like for example if the moisture is less in soil then we will get alert “your moisture has decreased water the plants” so that we can turn on our motor pumps to water. Here we are using thingspeak cloud for coding the arduino through IOT. Our project will also do its watering by itself when the moisture level decreases, this is done by soil moisture sensor. It is very reasonable and complete greenhouse can be constructed under Rs.10,000 which can save lots of money for the farmers. The crop yield will also be very good and this will be useful in increasing the economy of farming.

Plant Monitoring

Plants play a vital role in maintaining the ecological cycle, and thus, to maintain the plant's proper growth and health, adequate monitoring is required. Hence, the aim of the chapter is to create a smart plant monitoring system using automation and internet of things (IOT) technology. This topic highlights various features such as smart decision making based on soil moisture real-time data. For this purpose, sensors like soil moisture sensor, DHT11 sensor, level sensor, etc. are used. The soil moisture sensor measures the level of moisture (i.e., water content of different plants). The signal will be sent to Arduino board when the moisture level drops below the marginal value, which triggers the pumping of water into the plant by the pump. When the moisture level reaches absolute value, the pump is halted. The other condition for this process is level sensor. Level sensor senses the water level in the tank and sends the information of water level value to Arduino board and Arduino board to cloud. The whole data about the plant monitoring will be sent to the cloud server.

This paper deals with the one of the various innovative ways to irrigate a field or water the plants using solar power. Irrigation is needed in the fields or farms where is less availability of water , since agriculture plays one of the most vital role in increasing or decreasing our country’s economy . An improvising system is needed in order to ensure not even healthy growth of the plant’s but also reduction of the amount of water wasted during such activities. So, this project signifies a Smart solar irrigation system using Arduino, this project helps in opening and closing the water supply according to the moisture level in the soil and the moisture level in soil is calculated by the help of soil moisture sensor which is one of the most important component in this project. The smart solar irrigation system will have zero electricity cost as whole project runs on solar energy beside that it is a farmer-friendly project helps in reduction of cost of the men required in the field to irrigate and most importantly reduces the amount of water wasted in irrigation of the fields.

Agricultural Areas

One-third of our country's income is derived from agriculture. Due to the presence of many fertile lands and deltas, India has always been one of the largest producers of food. Agriculture is the means of living for people in India. Due to many constraints, the country's revenue from agriculture is always getting decreased. These barriers include sudden rain, fire damage, and loss of crops by animals, lack of capital and proper irrigation facilities and so on. One step resolution for this problem is to innovate traditional farming with some modern technologies especially in the forest areas. Automation in agriculture helps in solving the problems in farming. Internet of Things (IoT)’s intervention in farming can give a solution so that it reduces the problems faced by farmers in our country. IoT is a framework that deals with communication between things and these things include sensors, actuators and other digital machines. The proposed system consists of smoke sensor, soil moisture sensor and ultrasonic sensor, to understand events or changes in the environment such as soil moisture level, environmental conditions like presence of fire and the presence of animals in agricultural areas and send this information for further processing. Hence proper water pumping based on the soil moisture level, sprinkling of water to control the fire damage, activation of control mechanism to prevent the entry of animals into the fields, spraying of pesticides to control pests can be done. Therefore, this system mitigates the losses in agriculture in a better way and assures that this can contribute better yields, particularly near forest areas as the possibility of destruction by animals is high.

Working Principle

The Indonesian country which is famous for its tropical climate has now experienced a shift in two seasons (dry season and rainy season). This has an impact on cropping and harvesting systems among farmers. In large scale this is very influential considering that farmers in Indonesia are stilldependent on rainfall which results in soil moisture. Some types of plants that are very dependent on soil moisture will greatly require rainfall or water for growth and development. Through this research, researchers tried to make a prototype application for watering plants using ATMEGA328 microcontroller based soil moisture sensor. Development of application systems using the prototype method as a simple method which is the first step and can be developed again for large scale. The working principle of this prototype is simply that when soil moisture reaches a certainthreshold (above 56%) then the system will work by activating the watering system, if it is below 56% the system does not work or in other words soil moisture is considered sufficient for certain plant needs.
