Due to the indiscriminate use of drinking water through the system of flooding in an irregular way to the different plants in the gardens of the population of Arequipa; this research is presented, that integrates an IoT system that is executed in a Raspberry Pi and through its GPIO allows to control the electric solenoid valve; and with the Arduino Uno with its Shield Ethernet it achieves the monitoring in real-time, of the humidity of the soil and the water consumption of the gardens. Finally, with the integration of the Telegram instant messaging application, alerts are managed when the garden is dry or wet. The proposal generated significant savings in drinking water consumption for the Arequipa population.
