# Open Hardware

> The AgriHub360 Sensor is an open device. What is inside it, and what you can repair yourself.

The AgriHub360 Sensor is built from commodity modules and nothing inside is potted or glued shut. A part that fails can be replaced, and the sensor keeps its device id, its key and its field history.

## Firmware

The firmware reads the probe, posts through the [Hub](/devices/hub) every fifteen minutes or slower, and sleeps between readings. A reflashed board keeps the sensor's identity.
