The BME688 Arduino Library is a comprehensive driver for interfacing with the Bosch BME688 environmental sensor. This library provides functionality to measure temperature, pressure, humidity, and gas resistance, supporting various oversampling settings and operation modes.

A library for interacting with the ADS111x series 16-bit ADCs over I2C.

This library enables you to use Interrupt from Hardware Timers on an ESP32-C3-based board. These ESP32-C3 Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software timers using millis() or micros(). That's mandatory…
