Smart Zigbee 3-in-1 Floor Sensor

Smart soil sensor for optimal plant care

The smart soil sensor is the ideal solution for anyone who wants to keep their plants healthy and well-cared for. As a modern soil measuring device for plants, it provides precise data and helps ensure optimal conditions in the garden or at home.

Precise 3-in-1 real-time measurements

Reliably measure soil moisture, temperature, and light intensity with just one device. This combination enables a comprehensive analysis of growing conditions and helps achieve better results when caring for plants.

Smart app control

All measurements are displayed in real time in the Smart Life app. This allows you to keep an eye on your plants at all times and respond quickly—whether you are at home or on the go.

Energy-efficient thanks to Zigbee technology

Thanks to modern Zigbee technology, the sensor offers exceptionally low power consumption and a long battery life. Ideal for continuous use without the need to change batteries frequently.

Versatile for indoor and outdoor use

Whether in the garden, raised beds, on the lawn, or with houseplants, the smart sensor adapts flexibly to a variety of applications. Intelligent soil moisture monitoring helps optimize watering and conserve resources.

How does a soil moisture sensor actually work?

A soil moisture sensor measures the moisture in the soil using two methods: Resistive sensors determine the electrical conductivity between two electrodes, while capacitive sensors detect changes in the electric field. The measured values are output as a percentage or an analog signal.

What soil moisture values should my plants have?

Optimal soil moisture varies between 20 and 80 percent depending on the plant. Succulents prefer dry conditions at 20-40%, while tropical plants need 60-80%. Most houseplants thrive at 40-60% soil moisture.

How deep do I need to insert the sensor into the soil?

Place the soil moisture sensor about 5-10 cm deep in the substrate, near the root area. For larger plants, you can measure up to 15 cm deep. Make sure both electrodes are completely surrounded by soil.

What are the advantages and disadvantages of smart soil moisture sensors for irrigation systems?

Smart sensors enable automatic irrigation and remote monitoring via app, saving water and time. Thanks to Zigbee technology, they are particularly energy-efficient and last a long time on one battery charge – without fixed wiring or WLAN dependency. Disadvantages include higher acquisition costs, the need for a Zigbee gateway, and more complex setup than simple analog models.

How often do I need to calibrate my soil moisture sensor?

Calibration is recommended every 3-6 months or if the readings seem implausible. Test with completely dry and water-saturated substrate. More frequent adjustment is necessary if the location is changed often or with different soil types.

Are there alternatives to electronic soil moisture sensors?

Yes, mechanical moisture meters without batteries, tensiometers for precise scientific measurements, or the classic finger test also work. However, for automatic irrigation, electronic sensors with a 5V connection are the most practical solution.
