Ariel Rocholl has been working with Seed Studio on an affordable handheld spectrum analyzer called the RF-Explorer.
It’s a sort of Swiss Army Knife for monitoring, testing and diagnosing ISM band digital communications. It currently supports the 433Mhz, 868Mhz or 915Mhz bands and other bands in the works. The RF-Explorer is currently in beta with Seeed Studio.
I can see this coming in handy with my water meter reading project.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
So it can’t read my 27Mhz r/c car frequency?
You never know. I would check the projects main page and tell them what other add-ons or features your looking for. It never hurts to ask questions or give ideas. 🙂
