“Greetings and welcome back.
So here’s something cool: a room temperature and humidity meter that measures current room temperature and humidity and displays the readings on an SSD1306 OLED Screen.
AHT10 is being used here to get the Temperature and humidity data, and the whole setup is driven by an XIAO M0 MCU.
This whole meter is powered through the onboard 18650 lithium Cell through a power management IC Setup that boosts the 3.7V of the lithium Cell to 5V for the MCU, display, and sensor to work.
This Instructables is about how this setup was made and how you can make it in few easy steps, so let’s get started.
