Application |
Utilization |
Moisture sensor |
 |
It can measure the percent of water in soil. It measure dielectric permittivity of soil. |
Farmers get alert of the growing condition of the plants. |
Humidity sensor |
 |
It can measure the accurate air humidity level. |
Farmers get alert of the growth of leaf, change in photosynthesis level of the plants. |
PH sensor |
|
It can measure the ph value of soil. It determines which nutrient is available in the soil. |
Farmers get alert of the particular crop to grow in the field to get best production in terms of quality and quantity. |
Spoiled crop detection sensor |
|
It can detect the disease in crop in early phase by detecting the chemical compound released by an infected plant. |
Farmers get alert of quick and timely crop protection. |
Fertility sensor |
|
It can measure the fertility of the soil. |
Farmers get alert of the quality of the soil and accordingly choose the crop to plant. |
Climate sensor |
|
It can provide climate condition by measuring the CO2 level in air. Also monitor any faulty condition. |
Farmers get the data about the environment like wind speed, humidity etc. |
Temperature sensor |
 |
It can measure the temperature of the soil up to a certain depth from the surface of the soil. |
Farmers get alert of the change in absorption of soil nutrients by plants. |
Pressure sensor |
 |
It can measure the air pressure in a particular area depending on which rainfall on that particular area can be guessed. |
Farmers get alert of the higher or lower level of rainfall and accordingly plan to monitor the plants. |
Microcontroller |
 |
It detects signal from other devices and respond according to the process. |
Many works of farmers can be automated by it. |
