GARDENA smart Wireless Soil Moisture and Temperature Sensor 19040-20

The GARDENA smart Sensor Soil Moisture & Temperature Sensor 19040-20 is a wireless device for managing irrigation. It measures soil moisture and temperature at the root zone, so plants only get water when they need it. The data it collects helps prevent overwatering and supports healthy root growth. It works as part of the GARDENA smart system and sends live readings of soil conditions. It suits lawns and greenhouses. With this sensor, gardeners can base watering on actual soil conditions rather than a fixed schedule.

The sensor has a low-profile design, so it sits unobtrusively in the garden. To take reliable readings, push it into the soil up to the minimum-depth mark. It then transmits soil data to a smartphone or tablet via the GARDENA app. The housing is easy to install and remove, so you can move it between balcony pots, planters, and flowerbeds. Once connected to the GARDENA smart system, it can coordinate with other irrigation components through a single interface. The readings give precise control over water use, whether in a small balcony garden or a larger outdoor space.

• Wireless radio – sends soil readings to the smart system without cables.
• Requires GARDENA smart Gateway – acts as the link between the sensor and the mobile app.
• Condition-based irrigation control – cancels scheduled watering when the soil is already damp.
• Multi-environment compatibility – works in flowerbeds, terrace containers, and open ground.
• Visual placement guide – has a "min" mark on the probe for correct depth.
