T-Tissue: Tissue temperature (e.g., buds, cambium, wood) T-Surface: Surface temperature (e.g., bark) T-Soil: soil temperature or underwater temperature

    The T-series sensors are used for direct, continuous and high-precision temperature measurements. The various T-series models are designed specifically to record internal temperatures (T-Tissue), outer/surface temperatures (T-surface) on plants and other measurement objects, or for soil/water temperature (T-soil). These devices are suitable for long-term application in outdoor conditions. Due to their extremely low power consumption, Ecomatik T-sensors are ideal for battery-powered solutions, e.g. in IoT applications.

      Accessories & Compatible Products

      Data logging

      From small and compact solutions to fully developed measurement networks, Ecomatik offers turnkey system solutions for sensor data acquisition in any required size:

      • IoP systems (Internet of Plants) for wireless sensor data acquisition at freely positionable measurement points. Customer-specific preconfigured plug-and-play systems with online data visualization and data transmission via NB-IoT/LTE-M or LoRaWAN.
         
      • Mini systems with compact 4-channel data logger (DL18 and DL18-BLE) for flexible long-term measurements under field conditions. Compact and robust systems for connecting various sensors and decentralized measurement points.
         
      • Maxi systems for customer-specific system integration and individual measurement installations. From planning to implementation of complex measurement networks including sensors, power supply, and data transmission.
         
      • SDI-12 converter for analog signals for converting analog sensor signals into digital SDI-12 data. Enables the integration of ECOMATIK sensors into measurement systems without suitable analog inputs.

      Note

      The output signal of all Ecomatik temperature sensors is an analog DC voltage. In addition, digital SDI-12 interfaces are available depending on the sensor model. Our temperature sensors are therefore compatible with almost all common data loggers and microcontrollers with analog voltage input channels (e.g. Arduino) and can also be integrated into digital measurement systems via SDI-12. If you are unsure about the compatibility of an existing data logger or measurement system, please feel free to contact us at any time.

      Like so many things, everything started with an idea ...

      In the case of the plant scientist and founder of ECOMATIK, Dr. Liu, it was the idea that modern measurement technology should enable crucial plant physiological parameters to be measured directly, precisely and with high temporal resolution on the plant itself. It was obvious to him that there is an information potential of immense value in the detailed understanding of immediate reactions of plants to their environment...
