EnviroDIY/ModularSensors: v0.19.6: Modem Improvements & ADS1X15 Generalization

The EnviroDIY ModularSensors library gives environmental sensors a common interface of functions for use with Arduino-framework data loggers, such as the EnviroDIY Mayfly Logger. The ModularSensors library is specifically designed to support wireless, solar-powered environmental data logging applications that:

• Retrieve data from many physical sensors;

• Save that data to a SD memory card;

• Transmit that data wirelessly to a web server; and

• Put the processor, sensors and all other peripherals to sleep between readings to conserve power.

The ModularSensors library coordinates these tasks by "wrapping" native sensor libraries into a common interface of functions and returns. These wrapper functions serve to harmonize and simplify the process of iterating through and logging data from a diverse set of sensors and variables. Using the common sensor and variable interface, the library attempts to optimize measurement timing as much as possible to reduce logger "on-time" and power consumption. Although this library was written primarily for the EnviroDIY Mayfly data logger board, it is also designed to be compatible with a variety of other Arduino-based boards as well.

New in v0.19.6: Modem improvements & ADS1X15 generalization

• New Features:

  • Added ADS1015 as an optional analog to digital converter (ADC) for boards other than the Mayfly

• Improvements:

  • Modem waits for signal strength return before sending data

  • Other modem tweaks

  • Restructuring of data publishers

• Bug Fixes

  • Fixed bug with ADS1115 for M0/SAM21

New in v0.19.3: Bug fix and example re-working (released in January 15, 2019):

• Fixes bug in sending data to the WikiWatershed / Monitor My Watershed data sharing portal.

• Re-works the examples to remove duplication between them.

New in v0.19.2: Decreased Data Consumption (released Dec 22, 2018)

• New Features:

  • Added ThingSpeak support via MQTT (PubSubClient is now a required dependency)

  • Added support for TI INA219 thanks to @neilh21 (Adafruit INA219 library is now a required dependency)

• Improvements:

  • Reduced data consumption (by half in one test), by creating an outgoing text buffer. Note : the default buffer size is quite large, decrease it to decrease program memory size.

  • Refactored data publishers as a new class rather than subclasses of loggers
