How to display messages on a remote screen? The project combines two technologies to solve this problem.
A remote device with an e-ink display connected to an IoT-capable board to receive and display the messages.
A dashboard running on Node-RED to send the messages.
Pervasive Displays offers a wide range of e-paper screens, from 1.54” up to 12.2”, in black-and-white or black-white-red versions, as well as the Pervasive Displays Extension Kit Gen 3, a universal driver board.
The e-paper screens act like a sheet of paper: they only need power during the printing of the text or image. Once the text or image has been printed, the screens no longer need power. They can even be detached: the text or image stays on! A more detailed presentation explains How e-paper works.
Apart from the low power and the persistent display, the e-paper screens offer high readability even in direct sunlight and high resolution with 130 dpi.”
