I was struggling with constant headaches and suspected my home office setup was the problem. FieldSentinel revealed that my Wi-Fi router and monitor were generating way more RF radiation than I realized. After rearranging my desk, I genuinely feel better — and I finally have data to back that up.

Everything You Need to Monitor, Detect & Act
Triple-Axis All-Field Detection
Three sensors compute the true peak regardless of how you hold it. Covers magnetic, electric, and RF including 5G.
Readings You Can Actually Act On
FieldSentinel shows readings against building biologist benchmarks — under 1 mG magnetic and 100 µW/m² RF. Data you can act on.

Three-Color Alert System
A color-coded backlight paired with an audible buzzer gives you an unmistakable warning the moment radiation exceeds safe levels. No squinting at numbers — the signal is immediate and obvious.
No Technical Background Needed
One-button mode switching and a large backlit LCD get you reading real EMF levels within seconds. Unbox, scan, act.

Based On Real and Honest Experiences
We moved into a new house and I wanted to check EMF levels in the kids' rooms before setting anything up. FieldSentinel made the whole process straightforward — the color alert system meant I didn't have to interpret numbers, it just told me where to act. Found high readings near an old outlet that we had an electrician look at.
Honestly, I bought FieldSentinel half-expecting it to be a gimmick. I was wrong. The readings were consistent across multiple tests, the manual actually explains what the numbers mean, and the battery easily lasted through a full inspection of our house plus a neighbor's. Solid piece of kit at a price that doesn't hurt.
