Plant Monitoring With SMS Alert

Introduction: Plant Monitoring With SMS Alert

Here I create Plant monitoring with SMS alert. Server is not required for this alert system. It is very cheap and reliable project.

Step 1: Block Diagram of System

In today’s greenhouses, many parameter measurements are required

to monitor and control for the good quality and productivity of plants. But to get the desired results there are some very important factors which come into play like Temperature, Humidity, Light and Good Soil, which are necessary for a better plant growth. Keeping these parameters in mind I have built an Automatic Plant Monitoring System over GSM module using Arduino. This system is very efficient for growing good quality plants. The other important part of this project is that it is fully automatic and working on low voltage like; 5-12V DC supply.

Now a days GSM Module is widely used for sending SMS status of any kind of data. Here in this project by using SIM900A GSM Module we can keep information about the effects of climate on plants. The system shall also demonstrate climatic changes which affect the plant in its productivity and quality etc. The main purpose of coming up with this project is to build an Automatic Plant Monitoring in which GSM module sends the information about Temperature, Humidity, Light intensity, Soil moisture.

Because I am the Indian citizen, used SIM900A (A is stands for Asian network) module but you can used different kind of SIM module as per your country. The AT codes may differ.

Step 2: Component Detail

------------------ I measure four types of parameters, which are going

to discuss below: ------------------

Temperature and Humidity

The DHT11 sensor is used for sensing temperature and humidity. When the temperature and humidity are high the root of plants damaged and growth of plant not well.

Light Intensity

Light intensity is an important factor for the plant growth. For detecting light intensity LDR (Light dependent resistor) is used. Intensity of light is measured in LUX and therefore for demonstration 100 LUX light is used as defined or threshold level.

Soil Moisture

Soil moisture contain is very important for good growth of plants. Here Soil sensor is used to measure moisture content in Soil. Using with this sensor we can measure soil data in both way, analog as well as digital also.

SMS Notification:

When value of any of above parameters are exceeds from a defined level or critical level, the system automatically send SMS to the owner or the operator with information of related parameters and when the value comes in normal range or below the defined level again the system automatically send SMS to the owner or the operator with information of related data.

The notification send only once till the condition not change so the owner or operator having not getting frequent SMS. Therefore, lower SMS pack required.

Step 3: Circuit Diagram

These all parts are easily available at any online shopping site

or with well-known electronics spare parts dealer. All components datasheets are available on web. If any difficulty feel free to contact on my mail.

    Good idea. With a system like this I might actually be able to keep a few plants alive.
