From the project
Hệ thống giám sát chất lượng không khí trong phòng
An edge-computing Internet of Things (IoT) station designed for real-time indoor environmental quality monitoring and autonomous power management. Powered by an ultra-compact ESP32-C3 Super Mini (RISC-V) microcontroller, the device integrates multi-sensor environmental sensing (PM2.5, VOC, Temperature, Humidity, Pressure), on-device visual feedback (1.8" ST7735 TFT), local acoustic alerts, a rechargeable 2S Li-ion battery subsystem with real-time power telemetry (INA219), and cloud synchronization with Google Firebase.

Indoor-Air-Quality-Project: common questions
How many components are on the Indoor-Air-Quality-Project?
12 components, from 8 distinct parts. The full bill of materials is listed on this page.
Where can I download the Indoor-Air-Quality-Project design files?
From the DienKiku/Indoor-Air-Quality-Project repository on GitHub, which has the schematic; the links under Design files point to each one.
Can I use the Indoor-Air-Quality-Project design in my own project?
Yes, under the terms of its MIT license, which DienKiku chose for the repository.
Can I test firmware for the Indoor-Air-Quality-Project without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
