Weather & SD module

Obsolete product Please note that this product is now obsolete, and support for this product will end on May 10, 2021. For new developments, please refer to IoTaaP Wolffia and Q Link modules.

Weather & SD module incorporates Bosch's BME280 environmental sensor as well as micro SD card slot.

This module can be used as environmental sensor and/or data logger

Weather module is based on BME280 environmental sensor and it can provide measurements of the current temperature, pressure, and humidity. BME280 uses standard I2C communication protocol. This module also incorporates a standard micro SD card slot that can be used to log data or any other purpose required. The default I2C address is 0x76, and the alternative is 0x77, selected by soldering onboard jumper.
