enviro-monitor | environment monitor based on a Raspberry Pi Zero W

enviro-monitor is a Python library typically used in Manufacturing, Utilities, Machinery, Process, Internet of Things (IoT), Raspberry Pi, Arduino applications. enviro-monitor has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. However enviro-monitor build file is not available. You can download it from GitHub.

The case is not water resistant and needs to be sheltered from the elements. The base is only required if the unit is not mounted on a vertical surface. There is a variant of the case and cover for the Indoor Plus model that monitors eCO2 and TVOC levels. This variant of the case provides additional space and airflow for the SGP30 sensor. The case also has the option of adding a weather cover to provide additional protection from the elements. When using this cover, it is necessary to set "enable_display" in the config.json file to "false". That limits the display functionality to just air quality-based hue and serial number, as well as changing the temperature and humidity compensation variables to mitigate the effect of the cover on the temperature and humidity sensor. Approximate noise levels measurements have been added to Version 6, based on this repository. This feature has not been calibrated and is not to be used for accurate sound level measurements. Version 6.7 has improved frequency compensation of the noise level measurement function, using this, but still further work and calibration is required. This noise level measurement function requires additional setup (described below) and after setup, needs to be enabled in the configuration file. mqtt support is provided to enable the use of external temperature and humidity sensors (for data logging and regression analysis), interworking between the Enviro Monitor and a home automation system and to support interworking between outdoor and indoor Enviro Monitors. That interworking allows the display of an indoor Enviro Monitor to cycle between indoor and outdoor readings. An alternative to using mqtt-linked indoor and outdoor Enviro Monitors to get outdoor readings on an indoor Enviro Monitor, is to configure the indoor Enviro Monitor to capture Luftdaten readings or Adafruit IO feeds from another Enviro Monitor. Luftdaten interworking has been modified to support the addition of minimum, maximum and mean noise level readings. Noise level readings can be sent to Luftdaten by setting "enable_luftdaten_noise" to true in the config.json file. Note that Luftdaten can't currently be configured with three sensors per node, so noise level readings can therefore only be sent to Luftdaten if either PM or climate readings are disabled. That can be done by setting "disable_luftdaten_sensor_upload" in the config.json file to either "Climate" or "PM".
