How Antennino Works
Antennino operates in three main steps:
1. Data Acquisition
The microcontroller reads data from connected sensors, such as temperature, humidity, or light sensors.
2. Wireless Transmission
The radio module sends the collected data to another Antennino board or gateway over sub-GHz frequency bands. This method conserves power compared to Wi-Fi.
3. Data Reception
Another Antennino board or receiver captures the transmitted data and processes it for display, logging, or automation.
Example: A soil moisture sensor sends data from the garden to a remote board, allowing you to monitor soil conditions without visiting the garden.
