The architecture of the smart flowerpot by using the internet of things (IoT)

Abstract

Smart Flowerpot was a plant pot that helped growers reduced care time and watering for the plants, because the plant pot offered by the researcher had a soil humidity sensor that measured the soil moisture and sent the soil moisture to the processor using NodeMCU ESP8266. If the humidity level of the soil was lowered to the specified value, NodeMCU sent a signal to the relay module, to allow the water pump to water the plants and there was an ultrasonic sensor module to measure the water level that was put in for watering the plants. If the water supply had almost run out, the NodeMCU would send a notification message to the Line Notify of the owner of the smart flowerpot to refill the water and, in addition, the smart flowerpot was equipped with an RGB LED Module to show the soil moisture status. If the LED was green, it meant high humidity, yellow was moderate humidity, red was low, and users could also use the mobile application to manage and display sensor values in order to let them know the status of the smart flowerpots. The researcher designed the Architecture of Smart Flowerpot by using the Internet of Things and brought it to five Information Technology and Computer Science experts to assess the suitability. Overall evaluation, the average 4.55 SD 0.63, was suitable at the highest level.
