TL;DR
LeanMCU has developed an open-source firmware and a custom enclosure to turn Espressif's ESP32-C3 development boards and TE Connectivity's HTU21D environmental sensor into budget-friendly temperature and humidity monitors compatible with Home Assistant. The total cost for building each unit is under $10, making it an affordable solution for those wanting to monitor environmental conditions at home.
Why This Was Curated
This article provides a practical and actionable project for software developers looking to learn about hardware by using a popular ESP32-C3 board to create an environmental monitor. It is accessible with clear instructions and offers a unique approach by allowing firmware flashing directly from the browser, making it highly relevant and engaging for the target audience.
