Our DIY irrigation kit is controlled by a microcontroller connected to the sensor and a relay. The kit consists of an irrigation pump, hose, sensor shield, battery holder for four AA batteries, a soil moisture sensor and a relay module. The soil moisture sensor measures the moisture content of the soil. When the soil becomes dry, the sensor detects low moisture content and automatically turns on the water pump to supply water to the plant. Specifications: Capacitive soil moisture sensor: Operating voltage: 5 VDC Output voltage: 0 ~ 5 VDC Size: 59 x 20mm (LxW) Mini water pump: DC Voltage: 5V Water outlet outer diameter: 6.3mm: Inner diameter of water outlet: 4.1mm Water inlet diameter: 7mm Drive type: brushless DC design, magnetic drive Package includes: 1 x Microcontroller ATmega328 with USB cable 1 x capacitive soil moisture sensor 1 x 1 channel 5V relay module 1 x Mini water pump 1 x 1M vinyl hose 10x Jumper cable F-F 1 x Sensor Shield 1 x Battery holder for 4 AA batteries Automatic irrigation The system can detect low moisture in the soil and then automatically starts watering the soil. Caution recommended Do not pour water directly also the soil moisture sensor, because it will rust at high humidity. https://elecena.pl/product/25647307/plant-watering-kit-with-soil-moisture-detection-sensor-automatic-watering-module-diy-kit-automatic-water-pump 2024-03-28 https://elecena.pl/product/25647307/plant-watering-kit-with-soil-moisture-detection-sensor-automatic-watering-module-diy-kit-automatic-water-pump 2024-04-03 https://elecena.pl/product/25647307/plant-watering-kit-with-soil-moisture-detection-sensor-automatic-watering-module-diy-kit-automatic-water-pump 2024-07-18 https://elecena.pl/product/25647307/plant-watering-kit-with-soil-moisture-detection-sensor-automatic-watering-module-diy-kit-automatic-water-pump 2024-07-22 https://elecena.pl/product/25647307/plant-watering-kit-with-soil-moisture-detection-sensor-automatic-watering-module-diy-kit-automatic-water-pump 2025-03-21 https://elecena.pl/product/25647307/plant-watering-kit-with-soil-moisture-detection-sensor-automatic-watering-module-diy-kit-automatic-water-pump 2025-03-24 https://elecena.pl/product/25647307/plant-watering-kit-with-soil-moisture-detection-sensor-automatic-watering-module-diy-kit-automatic-water-pump 2025-05-30 https://elecena.pl/product/25647307/plant-watering-kit-with-soil-moisture-detection-sensor-automatic-watering-module-diy-kit-automatic-water-pump 2025-06-02
