Serial Air Quality Sensors

Data acquisition and logging for Air Quality Sensors with UART interface

Installation

This package can be pip installed. Please visit project site for detailed instructions.

Command Line Tools

This package provides tools for requesting new measurements from the sensors and print them on different formats, save them to a CSV file, or push them to an external service such as an MQTT or InfluxDB server. MQTT or InfluxDB server support requires additional packages. Please visit project site for details.

Particulate Matter Sensors

Other Sensors

• MCU680: chinese module with a BME680 sensor, a mirocontroller (μC) and 3.3V low-dropout regulator (LDO). The μC acts as I2C/UART bridge, providing outputs from the closed source integration library.
• MHZ19B: infrared CO2 sensor module from Winsen.

Want More Sensors

Use as a library

PyPMS/pms is meant as a command line application. The project site contain some help for those brave enough to use its internals as a library.
