bGeigieCast

General information

The bGeigieCast module was created to solve an issue with the existing bGeigieNano: The bGeigieNano can only be used as a mobile sensor. With the bGeigieCast module, the bGeigieNano can configures as a fixed sensor and send measurements directly to the API, without the need to manually upload log files.

Hardware

The bGeigieCast is a XBee module, which should be placed on top of the FIO (it replaces the BLEBee). The module consists of an ESP32 micro controller, a power switch, a mode button, and an RGB LED.

Additional hardware for a complete fixed mode sensor are:

• Wireless charging dock
• Wireless receiver, connected to the bGeigieNano
• Wireless transmitter

Modes

The bGeigieCast module knows 3 modes, one for configuring the module and two others for handling the measurements in different ways.

Configuration mode

Allows the user to connect to the module and configure different settings

Mobile mode

The module will publish measurements over bluetooth. Apps like Safecast Drive can be used to connect to the bGeigieCast

Fixed mode

The module will publish measurements every 5 minutes directly to the API. Configurations for this can be set while in configuration mode.

Interacting with the module

In the following
