IoT Based Smart Way of Watering Plants and Feeding Pets

Plants as well as the animals are most essential in our livelihood. Plants are beneficial for the oxygen reason, balance of nature and desires of humankind. On the other hand, pets are useful to decrease pressure, tension, and loneliness. Like human beings, additionally they need water supply and food supply to survive. For forests and wild animals, the nature presents all necessary conditions to stay. But, for farming, indoor plants and pets, people must provide all essential conditions in a smart way which includes water and meals. This paper shows that it is possible to provide water to the plants and food to the pets using ESP8266 Microcontroller when possessors are out of their homes for an important period of time. The soil moisture sensor connected to ESP8266 NodeMCU is used to detect the moisture level in the plant’s soil. If the obtained moisture level is below the set point, then a mobile application sends the notification to turn on the water pump so that the plant gets water supply. The servomotor connected to ESP8266 NodeMCU controls the food dispenser through slider in the Blynk App to provide food to the pets. Using ESP32 CAM we can monitor our pets and plants with the help of it’s live streaming feature. As a result, both the mechanisms can be activated simultaneously by creating two templates connected to the same device in the Blynk App.
