Backscatter Radio System
August 2024 - Present
I am currently in the process of developing a set of extremely low power wireless sensors that run off of scavenged RF power. The first revision of the project was able to run off of a 17dBm 433MHz carrier from up to one meter and transmit data from an enviornmental sensor. The next revision, built to operate in the S-band, will hopefully provide better performance, smaller size and be better characterized.
Below are photos of the most recent version of the sensor with its antenna attached, and the first version of the sensor with its antenna attached.
More updates to come…
If you too want to experiment with backscatter radio, I sell a backscatter radio module on my store page.
