Internet of things: automatic sprinklers in prototyping greenhouse using smartphone based android

Automatic sprinklers using a soil moisture sensor is formed based on microcontroller technology.The hard- and software system were designed to adapt the greenhouse prototype. The sensors were calibrated by comparing the value with the standard instruments. Observations were conducted on the kale seedsand it monitored for seven days. Based on the observation result, the sensorsable tomeasure temperature, humidity, light intensity, and soil moisture in the greenhouse. The automatic sprinkle pumped the water according to the values of soil moisture sensor. The values of those sensors have been delivered to webserver and android application. Moreover, the system is able to grow the kale plant in the greenhouseprototypevery well.
