Abstract

Spinach leaves are edible because of their high iron content, which is beneficial for the body. These leaves are often used as a source of daily vegetables. Temperature is the main factor that affects plant growth, if the temperature around the plant is too high, the plant will die. So an optimal temperature is needed so that the plant can grow well. Spinach plants cannot grow well if the water content in the soil does not match the needs of the plant. Likewise, pests can damage spinach plants and cause damage to their leaves. Therefore, a monitoring system is needed that can overcome this problem. The prototype of this tool is made using 3 sensor components, namely the DHT22 sensor functions to detect air temperature and humidity, a soil moisture sensor to read pH or soil moisture and a PIR sensor to detect the presence or absence of pest movement around the plant. The test results obtained that at a temperature of> 30ºC, the DC fan will automatically turn on. While at a temperature between> 27ºC - <30 ºC indicates the optimal temperature, the DC fan and lights will not turn on. Then at a temperature of> 27 ºC, the lights will turn on to stabilize the temperature, so that the temperature can return to optimal. All sensor reading data will be displayed on the Monitoring System developed with Internet of Things (IoT) based technology that can be controlled via the Blynk platform.
