Projects

Project 1. How UART Protocol Works – Gravity: UART Fiber Optic Transceiver Module

Introduction:

In this video, we will talk about the UART protocol. We’re using the Gravity: UART Fiber Optic Transceiver Module, which runs at 2,000,000 baud at any time within a distance of up to 10km, to make a professional weather station. The Gravity: UART Fiber Optic Transceiver Module ensures data integrity over these vast distances.

Project 2. Make a Weather Station Using Environmental Sensor

Introduction:

However, it only tells temperature in a relatively large range. Sometimes we need environmental parameters in a specific place like a fishpond, greenhouse, an open field, etc. By utilizing the Gravity: UART Fiber Optic Transceiver Module, I can monitor temperatures on my terrace from a long distance. So I decide to make a weather monitoring station that outputs real-time data using the Gravity: UART Fiber Optic Transceiver Module.
