New Format, Simpler To Use, Easy To Program, Longer Battery Life, New Moisture Resistant Coating, Brighter Display And Stronger Vibration Mode

3rd Party Certified RF Detector With Full Frequency Response From 700MHz to 9GHz 


The first of its kind, the Safe and Sound Micro RF Detector is wearable wristband detector. An innovative product of our own design and engineering, this device will notify you with a small vibration when environmental wireless radiation exceeds your desired exposure level. Moreover, with a push of a button, a color-coded light display will indicate the intensity of surrounding exposure.

Allows for 24/7 monitoring of your environment 


Allows for 24/7 monitoring of your environment, Safe and Sound Micro RF Detector is small, compact, durable and discreet. Super sensitive detection, designed with the electro-hypersensitive person in mind. Accuracy fully certified, operates on a rechargeable battery. Easy to use and understand; no technical experience required. 

There are three button actions that work when the unit is unplugged from USB. These button actions work identically no matter what the unit is doing. There are no multiple functions to learn.

There is one USB action - when the unit is plugged in, the button is disabled and the unit charges and displays battery level. This happens no matter what the unit is doing when you plug in power.

1. Single Click
2. Multi Click
3. Button Hold

1. Single Click

  • Click once and wait ~ 0.75 seconds for action to take place
  • Works identically in ANY mode
  • If LEDs are OFF, Turns LEDs ON (measurement mode)
  • If LEDS are ON, Turns LEDs OFF (monitor mode)

2. Multiple Clicks (each click must happen within 0.75 seconds of the previous click)

  • Click button sequence -> All LEDs come on for 1 sec -> RF Vibrate Threshold Displayed while unit vibrates the same number of times that button was clicked -> All LEDs go off and unit is in "LED off monitor mode"
  • Works identically in ANY mode
  • The LED color-coded light display identifies eight exposure levels:

Green = 10 µW/m² (two clicks)

Yellow = 100 µW/m² (three clicks)

Orange = 1,000 µW/m² (four clicks)

Red = 10,000 µW/m² (five clicks)

Red slow blink = 100,000 µW/m² (six clicks)

Red fast blink = 1,000,000 µW/m² (seven clicks)

No vibration (eight clicks)

3. 3+ Second Button Hold

  • Hold button down and wait until unit vibrates 3x -> unit shows all LEDs -> displays battery level -> powers off
  • Works identically in ANY mode

4. USB plugged in

  • Plug in USB power -> enters charging mode and indicates battery level -> BUTTON DISABLED
  • Unplug USB power -> Enables button and resumes operation
  • Works identically in ANY mode

    What I think so far.

    Posted by Brenda Letcher on 21st May 2024

    First of all, I received the product very quickly and it was very well packaged! I did not properly read the little insert, I was expecting a big manual. So I ended up phoning the company to ask them how to shut it off. Ha! They were very good. I am still reading the website, as I don't understand all of the information. What I do see is how the Wi-Fi impacts my rented living space! The router is above me, but very strong in my living room, bedroom and kitchen. There is one room, and the hall and bathroom that are in the green zone. So I have moved a foam mattress into this other room for sleeping. I have symptoms from EMF's that I never thought of. I am hoping that my overall health will improve. When I am in the yard, I can find a safe space without the neighbour's interfering Wi-Fi. Also, every restaurant, library, grocery store have very high RF readings. I have a 2006 car and it is safe! My daughter can't wait to see if her new vehicle is in the red zone as it is very digital. I gave it 4 stars instead of 5 because it runs out of power sooner than I thought. I just have to be conscious of recharging it. It is simple and discrete too! Thanks for a great product!

    EMI monitor

    Hard to understand how it works but once you get it, it is a good tool to prevent EMI high exposure.

    Safe and Sound Micro 2.1 Wearable RF Detector

    Posted by Laura Kissmann on 15th Oct 2023

    I desperately wanted to order this but was skeptical that I really did not need it. Well the skepticism is gone as it has been so enlightening to have this meter on vibrate around other people and finding hot spots and being able to ask for cell phone etiquette (eg sitting at dinner for extended time with a cellphone hidden in a pocket I would not have known was radiating). Also, without it I would not have realized that where my dog bed was located on the floor directly above the router and needed relocation for the health of pets sleeping there. One tip - I would try a leather band next time as the silicone one is awkward to put on with my small wrist.

    Micro RF meter

    Posted by Unknown on 3rd Aug 2023

    I have the original Micro RF meter and have only good things to say about it. Previous to purchasing the Micro I relied on the Safe and Sound Pro II but the Micro takes things to a different level. I have it set to vibrate which I can hear across the room if it is not on my wrist. The first thing I learned from the Micro is that EMF is not steady, it's a wave. Walking around a public library seeking a table in proximity to a wall outlet caused me to realize there were hot and cold spots in the room. Thank you, Micro, for showing me the (relatively) "safest" place to sit. Wearing Micro in a large busy hotel was hugely informative concerning the environment itself and which areas were hotter than others. (The entire environment was unhealthy and in the hotel room I unplugged everything...TV, wifi, cordless phone.) The Micro has upped my awareness enormously. When standing in proximity to someone and Micro vibrates, I know s/he has a live phone on them and I take a step or 2 back. Micro is a game changer because it invisibly alerts the wearer who then can take evasive maneuvers as desired. Excellent!
