Abstract :
Agriculture in Indonesia, especially in Bengkalis Regency, is the main source
of meeting food needs. Water irrigation is very important so that the plants thrive.
Water irrigation by farmers is still done manually, where to water the plants one
by one and then have to wait until all the plants are wet or by carrying a container
and watering manually with human power. Then the tool that will be made with
remote control system technology is by using IoT (Internet of Thing). This tool
works to detect the level of moisture in the soil that can be seen through a
smartphone so that it can keep the soil condition moist. Besides being able to be
monitored via a smartphone, this tool can also monitor soil moisture through the
LCD. For irrigation, it is controlled automatically through nodemcuesp8266
according to the soil moisture that has been set with the soil moisture standard for
fertile body plants. While nutrition can be controlled remotely using the blynk
application. The results of the tool test show that the humidity sensor has an input
voltage between 3.14 to 3.27 Volt DC but the output voltage reaches 1.08 to 3.12
Volt. The accuracy of the humidity sensor is almost close to the actual measuring
instrument with the largest error value is 0.13% and the smallest is 0%. There are
3 types of soil that can be used for humidity sensors, namely peat soil, clay,
beachfront soil because conditions in Bengkalis only have 3 types of soil.
