HMC5883L Magnetometer¶
The hmc5883l
allows you to use your HMC5883L triple-axis magnetometers
(datasheet,
Adafruit) with ESPHome. The I²C Bus is required to be set up in your configuration
for this sensor to work.
# Example configuration entry
sensor:
- platform: hmc5883l
address: 0x1E
field_strength_x:
name: "HMC5883L Field Strength X"
field_strength_y:
name: "HMC5883L Field Strength Y"
field_strength_z:
name: "HMC5883L Field Strength Z"
heading:
name: "HMC5883L Heading"
oversampling: 1x
range: 130uT
update_interval: 60s
Configuration variables:¶
address (Optional, int): Manually specify the I²C address of the sensor. Defaults to
0x1E
.field_strength_x (Optional): The field strength in microtesla along the X-Axis. All options from Sensor.
field_strength_y (Optional): The field strength in microtesla along the Y-Axis. All options from Sensor.
field_strength_z (Optional): The field strength in microtesla along the Z-Axis. All options from Sensor.
heading (Optional): The heading of the sensor in degrees. All options from Sensor.
oversampling (Optional): The oversampling parameter for the sensor.
update_interval (Optional, Time): The interval to check the sensor. Defaults to
60s
.oversampling (Optional): Number of readings to average over for each sample. One of
1x
,2x
,4x
,8x
. Defaults to1x
.range (Optional): Select a range / gain preset. This does not affect the scale of the values published but allows one to avoid overflows at the cost of reading resolution. Supported values are 88µT, 130µT, 190µT, 250µT, 400µT, 470µT, 560µT, 810µT. Default range is ±130µT.
id (Optional, ID): Manually specify the ID used for code generation.
Oversampling Options¶
By default, the HMC5883L sensor measures each value 1 times when requesting a new value. You can, however, configure this amount. The result is the sensor will take the adverage of the x samples. Possible oversampling values:
1x
(default)2x
4x
8x
Range Options¶
By default, the HMC5883L sensor measurement range is 130uT. You can, however, configure this amount. Possible values:
88uT
130uT
(default)190uT
250uT
400uT
470uT
560uT
810uT
