+# The macro below assumes you have a BME280 sensor_type defined in one
+# of the applicable sections in printer.cfg, such as:
+#
+#[temperature_sensor my_sensor]
+#sensor_type: BME280
+#gcode_id: AMB
+#
+# Note the format of the parameter SENSOR in the macro below.  The BME280
+# sensor status can be accessed using the format "bme280 <section_name>".
+# The example section above is named "my_sensor", thus the bme280 can be
+# queried as follows:
+#
+# QUERY_BME280 SENSOR='bme280 my_sensor'
+#
+# Since a default parameter is defined one could simply enter QUERY_BME280
+# as well.
