Hydra100 - (Heat, Humidity and Salinity)
Happi100 - (Heat, Humidity and Oxygen)

Soil Scout is a brand known for its wireless, underground sensor solutions. Two main sensor models stand out: Hydra100 and Happi100. Both collect data from deep within the soil, providing vital information for smart agriculture and green area management, but they have a key difference.

​

 

1. SoilScout Hydra100

 

The Hydra100 is Soil Scout's primary and long-standing wireless underground sensor model. It's designed to measure fundamental soil parameters:

- Measured Parameters:

  • Moisture: Precisely measures the water content in the soil.

  • Temperature: Determines soil temperature, which is crucial for plant growth and water evaporation.

  • Salinity / EC (Electrical Conductivity): Measures the electrical conductivity of the soil, indicating the level of nutrient salts and overall salinity.

 

- Key Features:

  • Fully Buried and Wireless: It's invisibly placed underground and requires no cable connections. This prevents interference with maintenance activities and protects it from external factors.

  • Long Battery Life: Offers up to a 20-year battery life when buried underground.

  • Maintenance-Free: Once installed, it requires no maintenance, such as battery replacement or calibration, for many years.

  • Real-Time Data: Transmits collected data regularly (e.g., every 5-55 minutes) to the cloud via a Base Station, ensuring constant online access to data.

  • Durable: Designed to withstand harsh underground conditions.

The Hydra100 is a fundamental and comprehensive solution, especially for irrigation management, fertilization optimization, and general soil health monitoring.

2. SoilScout Happi100

 

The Happi100 is Soil Scout's newer generation sensor, adding the crucial ability to measure oxygen levels, vital for plant root health. Its name comes from the Finnish word for "oxygen" (happi)

- Measured Parameters:

  • Oxygen: Measures the oxygen concentration beneath the soil. This is critical for root respiration. Root hypoxia (lack of oxygen) begins when oxygen levels drop below 10%, and if this lasts for more than 4 hours, it can lead to root death.

  • Moisture: Also measures soil moisture levels.

  • Temperature: Also determines soil temperature.

 

- Key Features:

  • World's First Underground Oxygen Sensor: It's the first sensor on the market capable of continuously and permanently measuring underground oxygen levels.

  • Integration with Hydra100: The Happi100 seamlessly integrates with SoilScout's existing platform and Hydra100 sensors. Users can add the Happi100 to their current systems to start monitoring soil oxygen data as well.

  • Fully Buried, Wireless, and Maintenance-Free: Like the Hydra100, the Happi100 is fully buried, wireless, and maintenance-free thanks to its long-lasting battery.

  • Precise Data: Provides precise oxygen measurements using galvanic cell sensor technology.

The Happi100 is specifically designed to detect and manage oxygen deficiency issues such as root suffocation due to over-irrigation, drainage problems, or soil compaction. This is a critical parameter for optimizing turf health and plant yield.

​

 

Key Difference Between Hydra100 and Happi100:

 

  • Hydra100: Measures Moisture, Temperature, and Salinity (EC).

  • Happi100: Measures Moisture, Temperature, and Oxygen.

 

While the Hydra100 offers fundamental soil health parameters, the Happi100 adds the crucial monitoring of oxygen levels for plant root health to this package. When used together, these two sensors provide a much more comprehensive and in-depth understanding of the processes occurring beneath the soil, enabling proactive and efficient field management.
