# 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 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.
#i2c_speed:
# 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
# "heater_generic" prefix). These heaters behave similarly to standard
# heaters (extruders, heated beds). Use the SET_HEATER_TEMPERATURE
