“Use two 915MHz radios to send/receive current environmental information and display it in real-time up to 350 meters away!
It’s almost gardening season, which means monitoring your plant beds for adequate sunlight, warmth, and pesky critters is more necessary than ever. But, there’s an issue; most IoT gardens rely on WiFi, which can be a large problem if your garden happens to be more than a couple hundred feet away. A potential solution is logging the data and reading it back, but that can’t occur in real-time, and using a cellular network costs a lot of money. This project aims to solve that issue by utilizing a pair of Adafruit M0 Feathers with integrated RFM69 radio modules to provide real-time monitoring across a large distance.”
