:: Product Information



Wireless sensor network that allows growers and researchers the ability to…

  • Monitor crop and soil microclimates for:

    • Soil moisture/irrigation scheduling

    • Insect and disease pressures

    • Frost/temperature alerts

    • Plant growth

    • Additional sensor inputs

  • Transmit data in rolling/complex topography

  • Collect site specific data with one system

  • Mesh networks are "self-healing," since the network automatically finds the fastest and most reliable paths to send data, even if nodes (Pups) are blocked or lose their signal


Applications for Plant Management

?  Monitor frost temperatures for real-time decisions to protect crops
?  Track soil moisture and EC in numerous locations for better irrigation practices
?  Record temperature and humidity for decisions regarding disease and insect pressure


Network Components

WatchDog Retriever

Retriever logs sensor data from its network of Pups (max 16 Pups per network).

  • Single button operation: switch modes, download data, upload configuration, and check battery status

  • Tri-colored LEDs indicate mode, battery level, data communication status, and configuration status

  • Non-volatile memory preserves your logged data, even when the batteries are removed

  • Transfer data or configuration information via flash drive or direct PC connection

  • Internal flash memory on the Retriever will hold approximately 6 months of data for a 10 Pup network using 15 minute logging intervals

  • Spectrum-supplied USB flash drive will hold several years of data at the Retriever for a 10 Pup network using 15 minute logging intervals

  • 3.5mm stereo port for computer connection USB cable (included)

  • AUX port for wireless (DataScout Cellular or WiFi modem) communication connection

  • Includes six non-rechargeable AA batteries (8 months typical life)

  • DC port for optional AC/DC power adapter (Max 17VDC)

  • Optional solar package includes rechargeable battery pack (2200 mAh, 7.2V NiMH), and 5W solar panel

  • Retrievers are available in both 900 MHz (US customers) and 2.4 GHz bands (international customers)

  • Retriever & Pups Launch Utility software included on USB flash drive

WatchDog Pups

Each Sensor Pup within the network is compatible with a diverse number of sensors and offers flexibility by allowing the grower to monitor the sensor inputs they require.

  • Pups are available in 3 types: Sensor Pup, Station Pup, and Repeater Pup

  • Single button operation: check battery status, signal strength, and join sensor network

  • Tri-colored LEDs indicate battery level, signal strength, and data communication status

  • Includes six non-rechargeable AA batteries (8 months typical life)

  • Communication range of 2,500 ft (about 1/2 mile), line-of-sight installation recommended between Pups or Retriever

  • Pups are available in both 900 MHz (US customers) and 2.4 GHz bands (international customers)

WatchDog Sensor Pups

  • Connect up to 4 external sensors via 2.5mm stereo-plug

  • Can monitor high, low, current, and average values for each sensor during each logging period

WatchDog Station Pups

  • Connects to your existing WatchDog 2000 Series Full and Mini Weather Stations

  • Sends all Weather Station sensor data to your Retriever network

  • No external sensors, can only be connected to another device

WatchDog Repeater Pups

  • Provide added range to WatchDog Retriever networks

  • Serves as a “hopping node” around buildings or obstacles, or over high sections of your fields

  • No external sensors can be connected


Detailed Product Information

External Sensors

  • Customize each WatchDog Pup to monitor only the parameters you need

  • Most Spectrum sensors are Pup-compatible, including :

    • Soil Moisture Sensors (WaterScout SM 300, WaterScout SMEC 300, and Watermark sensors)

    • LightScout Light Sensors (Solar Radiation, UV, and Quantum light)

    • Leaf Wetness Sensors

    • Temperature and Humidity Sensors

    • Barometric Pressure Sensors

    • CO2 Sensors

    • Rainfall and Wind Speed/Direction Sensors (available late-2015)

    • We also offer Pre-Packaged Pups - these include a custom mounting bracket and sensors
