temp_event_sensor.h

//  Instance of Sensor that reads the BME280 temperature sensor connected via SPI port.
//  This is an example of an Event-based Sensor, which signals an event/semaphore when sensor data is available.
//  The other sensors are Polling-based Sensors, which will block the program until the sensor data is available.
//  Event Sensors are better for multitasking.  Caller must use a semaphore to prevent concurrent access to the SPI port.
