Soil moisture
Follow changes in moisture where the probe is placed and compare them with plant appearance and watering history.
Root & Relay garden sensor
Understand what is happening beneath your plants.
A garden soil sensor can show you changes that are easy to miss by sight alone. Root & Relay brings moisture, electrical conductivity, root-zone temperature, and UV readings into one garden view, where Karpos can help put those signals in context.
Read the root zone
Four readings. A clearer garden picture.
The Root & Relay sensor is designed to add measured context to the observations you already make. Readings are most useful as trends, interpreted alongside the crop, weather, garden photos, and recent care.
Electrical conductivity (EC)
EC shows how readily the soil solution carries an electrical current. It is directional context for dissolved salts and nutrient availability, not a reading of individual nutrients.
Root-zone temperature
See temperature changes around the probe and consider them with local weather and the crop’s growing needs.
UV readings
Use the sensor’s UV readings as additional environmental context. They do not replace a full measure of sunlight or shade across the garden.
From data to next steps
Sensor readings make more sense together.
One number rarely explains a garden problem by itself. The Root & Relay app brings sensor trends together with garden notes, selected plant photos, and local weather. Karpos uses the available context to explain what may be changing and suggest practical checks.
- Compare moisture and temperature changes over time.
- Use EC as a trend signal, not a nutrient-by-nutrient diagnosis.
- Upload a plant photo when you want Karpos to consider visible symptoms.
- Review recommendations yourself; Karpos does not automatically change irrigation settings.
Prototype status
What is confirmed—and what is still being tested
Current prototype
Prototypes collect soil moisture, EC, root-zone temperature, and UV readings. The camera has been removed; the sensor does not take photos.
Connectivity and power
The prototype connects to home Wi-Fi. The production design uses a battery with solar charging. Outdoor range, outage behavior, battery capacity, and runtime are still being tested.
Placement and coverage
A sensor reports conditions at its placement. Recommended coverage, final specifications, measurement performance, and outdoor durability are still being tested.
We will publish validated production specifications as testing is completed. See the FAQ for current availability and plan details.
