Summer means sunshine, holidays, and well-deserved relaxation – but also dried-out lawns and drooping plants. While you’re away, your garden may be struggling with the heat.

Don’t worry – we’ve got a competent helper for your green oasis: the HARDWARIO Soil Moisture Sensor. With it, you can watch your plants from anywhere, even hundreds of kilometers away.

🪴 What You’ll Need

The HARDWARIO Soil Sensor Set is designed to be easy to assemble, even for beginners:

• HARDWARIO Hub
  
• Core Module (the brain of the solution)
  
• Sensor Module
  
• Soil Sensor (for measuring soil moisture)
  
• Mini Battery Module (for power supply)
  
• and the HARDWARIO Playground software
  
  

You can find everything you need in our HARDWARIO Store. *

🧰 Build it, Connect it, Monitor it

Once you’ve assembled the modules, simply flash the pre-made firmware, pair the device with the USB radio dongle, and connect it to Node-RED. You can configure the data you want to track – moisture, temperature, or both.

The whole setup is open-source so that you can adapt it to your needs – whether you’re a DIY enthusiast, a gardener, or both.

🌐 Monitor from Anywhere

You can see your data in easy-to-read graphs or set up alerts to notify you when the soil gets too dry. No more guesswork, just water when it’s needed. This helps you save both water and time.

‍

🏡 Perfect for Indoors and Outdoors

The sensor works in:

• indoor flowerpots
  
• balcony planters
  
• greenhouses
  
• garden beds
  
  

It can easily handle outdoor use with the proper enclosure (like an IP-rated box).
