+# HTU21D family two wire interface (I2C) environmental sensor.
+# Note that this sensor is not intended for use with extruders and heater beds,
+# but rather for montitoring ambient temperature (C) and relative humidity.
+# See sample-macros.cfg for a gcode_macro that may be used to report humidity
+# in addition to temperature.
+#[temperature_sensor my_sensor]
+# See the "temperature_sensor" section below for a description of its
+# parameters. The parameters below describe HTU21D family sensor parameters.
+#sensor_type:
+# Must be "HTU21D" , "SI7013", "SI7020", "SI7021" or "SHT21"
+#i2c_address:
+# Default is 64 (0x40).
+#i2c_mcu:
+# MCU the sensor is connected to. Default is the primary mcu.
+#i2c_bus:
+# The I2C bus the sensor is connected to. On some MCU platforms the default
+# is bus 0. On platforms without bus 0 this parameter is required.

+# The I2C speed (in Hz) to use when communicating with the sensor. Default
+# is 100000. On some MCUs changing this value has no effect.
+#htu21d_hold_master:
+# If the sensor can hold the I2C buf while reading. If True no other bus
+# comunication can be performed while reading is in progress.Default is False
+#htu21d_resolution:
+# The resolution of temperature and humidity reading.
+# Valid values are:
+# 'TEMP14_HUM12' -> 14bit for Temp and 12bit for humidity
+# 'TEMP13_HUM10' -> 13bit for Temp and 10bit for humidity
+# 'TEMP12_HUM08' -> 12bit for Temp and 08bit for humidity
+# 'TEMP11_HUM11' -> 11bit for Temp and 11bit for humidity
+# Default is: "TEMP11_HUM11"
+#htu21d_report_time:
+# interval in seconds between readings. Default is 30

# Generic heaters (one may define any number of sections with a

# heaters (extruders, heated beds). Use the SET_HEATER_TEMPERATURE
