The turfRad Moisture Sensor is the scientific-grade “engine” of the turfRad mapping system. Engineered in Switzerland, this is a non-contact, passive radiometer that accurately measures soil moisture by listening to the earth’s natural energy. It operates in the protected 1400-1427 MHz L-band, capturing highly-accurate, root-zone moisture data without interference.
Passive L-Band Technology: Operates as a “receive only” sensor, listening to the soil’s natural passive microwave brightness temperature for the most accurate, non-intrusive measurement.
Protected Frequency: Uses the 1400-1427 MHz band, which is protected for earth observation, meaning no interference from Wi-Fi or cellular signals can corrupt your data.
High-Precision GNSS::Goes far beyond GPS. It integrates L1C/A, L2C GLONASS, Galileo, and BeiDou for pin-point locational accuracy for every single measurement.
Seamless Connectivity: Onboard Wi-Fi (2.4 GHz) and Bluetooth allow for the automatic, wireless transfer of data to the turfRad platform for real-time map generation.
Low-Power & Durable: Consumes only ~4W of power (11-15V DC) and is built to operate in tough conditions, from -20°C to +50°C.
Certified & Compliant: Fully certified for FCC, CE, IC, and ROHS compliance for professional and safe operation.

Scientific-Grade Data: This isn’t a simple moisture probe. It’s a scientific radiometer that provides data on par with earth-observation satellites, but for your specific course.
Interference-Free:By operating in a protected band, you can trust your data is 100% pure and reflects your soil, not radio noise.
The Core of the System: This sensor is the “brain” that works seamlessly with the turfRad Universal Mount and software platform to deliver a complete, automated mapping solution.
Q: What does “passive” measurement mean?
A: It means the sensor is “receive only.” It doesn’t send any signals into the ground. It listens to the faint, natural microwave energy (brightness temperature) emitted by the soil, which is the most accurate, non-intrusive way to measure moisture.
Q: Why is the L-Band (1400-1427 MHz) special?
A: This band is globally protected for radio astronomy and earth observation. This is a huge advantage, as it guarantees the sensor is collecting data from the soil, not interference from cell phones, Wi-Fi, or other electronics.
Q: Can I buy just the sensor?
A: The sensor is the core component, but it’s designed to be part of the complete turfRad system. To function, it must be paired with the turfRad Universal Mount v3 (or a custom mount) and the turfRad software platform to process and visualize its data.
