The Smart Sensor to Know When Your Plants Need Water
Check the Ground from Your Phone
The smart soil sensor is available in a WiFi or Zigbee version , so you can choose the solution that best suits your home automation system. The WiFi version connects directly to your 2.4GHz home network, while the Zigbee version requires a Tuya compatible Zigbee gateway to function properly. Using the Tuya Smart / Smart Life app, compatible with iOS and Android smartphones, you can easily check soil values directly from your phone. The app displays soil moisture , temperature , and allows you to switch between °C and °F , so you always know if your plants need water or if conditions are right. It's a practical solution for pots, vegetable gardens, greenhouses, gardens, and smart irrigation systems. With the data always available in the app, you can monitor the condition of the soil even remotely and create automations with other compatible Tuya devices, such as pumps, smart plugs, or automatic irrigation systems.
You know right away when your plants need water
With the Tuya soil sensor, you no longer have to check your soil manually or rely on intuition. The app updates data approximately every 60 seconds and clearly shows soil moisture and temperature, so you can immediately know when it's time to water. It's a very convenient solution for those who want to take more care of potted plants, vegetable gardens, gardens, and greenhouses. By viewing the history in the app, you can see how soil conditions change throughout the day and manage irrigation more intelligently. This means less water waste, less risk of forgetting, and always monitoring your plants more precisely, right from your phone.
Your plants get watered when they really need it
Just insert it into the soil and you will immediately know how your plants are doing.
Using it is simple: insert the sensor into the soil, wait a few minutes, and monitor everything from the app. For the most accurate reading, the probe should be inserted into the soil at least 2/3 of its length , so the sensor can better detect the actual moisture near the roots.
The app alerts you when it's time to change the batteries
You don't have to remember to check the batteries manually. The sensor shows you the charge level directly in the app and alerts you when the batteries are running low. It runs on two easily replaceable AAA batteries , so you can continue monitoring the ground without interruption.
Resistant and practical to leave in the ground
Constructed of PC + ABS , sturdy and lightweight materials that make it suitable for everyday use with plants, pots, vegetable gardens, and greenhouses. Once inserted into the soil, it can remain in place to monitor humidity and temperature directly from the app. It's a convenient solution for those who want to better monitor their plants without constant manual checks. More convenience, more control, and a compact device designed to accompany day-to-day garden care.
Suitable for potted plants, vegetable gardens, gardens and greenhouses
The Tuya soil sensor can be used in various growing environments, such as indoor plants, windowsill pots, vegetable gardens, gardens, greenhouses, and flower beds . Inserted into the soil, it detects humidity and temperature and sends the data to the Tuya Smart / Smart Life app, allowing for easier and more precise monitoring. It is useful both for the daily care of houseplants and for those who manage multiple green areas and want better control over when to water. Thanks to its compact size, it can be easily placed in pots, boxes, cultivated soil, or small growing spaces.
Small, practical and ready to check the soil every day
