Wi-Fi Soil-Moisture Sensor

Digitalize your garden using this sensor, control the status of your plants soil and get automatic notification about critical moisture level. It simplifies the care about the flowers and keeps them healthy. The sensor makes creating of healthy environment an easy and funny task. This is the garden of 21th century. 



  • Using of the common Wi-Fi network (no additional IoT equipment needed)
  • Moisture level on the roots deepth - not on the top layer
  • Overwatering and underwatering issues solved
  • Graphical visualization vs time (days, weeks, monthes)
  • Encrypted Telegram Message Notation for critical moisture levels
  • USefull fordecorated soils (with stones, shells, tree bark, etc).
  • Calibration adopts sensor to different soils
  • Integration into existing SmartHome systems with MQTT and HTTP interfaces (for example: OpenHAB, HomeAssist)
  • Saves money and environment due to rechargeable battery (up to 1 year operation with 1 charge)

  • Consumption:
    • Stand-by mode: 150uA
    • Working mode: 80mA
  • Size: 10x3.5x2cm
  • Configuration - over Wi-Fi

Applications and user cases:

  • Homes and offices plants
  • Greenhouse and atriums
  • Plants ground covered with decor - stones, seashells, glass
  • Real estate management 
  • Difficult to reach places


Data visualization:  measurement graphs can be visualized on the ThingSpeak on the Web or using Apps also with HTTP or MQTT in OpenHAB or other IoT systems.


Setup: Easy install of the device over the Wi-Fi using any smartphone or PC.


  • Telegram - alarms customer with Telegram messages in case of  low or high level of moisture 
  • ThingSpeak - IoT portal visualizes data as graphs and defines scenarios with other devices and services (WhatsApp, etc). User can view the measurement data using Apps for iOS and Android (see ThingView as an example)
  • HTTP URL - sends data to dedicated URL address. This let integrate the device into digital eco-system of the company or web-sites
  • MQTT - is dedicated IoT web interface for IoT systems. It connects IoT devices together for number of different cases


  • Sensor is not visible in the network during the stand-by time
  • Password doesn't sent over Wi-Fi
  • Sensitive data is encrypted in the storage

Scalability : the gadget can be integrated in other systems via available protocols (MQTT, HTTP, TS), there are many third part services which can scale this system (check SmartHAB for example). One can use 3rd part watering and lighting systems supporting these protocols


Sensor can be combined with IoT Clock2.0
