Thought I would share the little display I’ve been working on. The idea was to make a sub $10 display that could be put anywhere. One by the bed, one in the kitchen, one by the back door, one in the workshop, one at work – you can never have too much weather info! The primary goal was to display temperature and RH. Something that was always on and I could just glance at. No need to get my phone/tablet out.
Its uses a wifi microcontroller (Wemos Lilon ESP8266) and a cheap display (Nokia 5110 clone). There is a micropython script running which updates the display every minute with data from the web.
I’ve also connected an SHT31 temperature/RH sensor for indoor values. The display while cheap is very limited (84x48 pixels). The idea is to mount in a box with touch buttons to switch to additional data (pressure, wind direction, speed, rainfall, radiation, UV) and to turn on the backlight. Currently, USB powered but I hope I can run it from a battery. Although that might be beyond my programming and electronics skills.
