Infineon XENSIV™ DPS3xx Pressure Sensor

The xensiv_dps3xx_i2c sensor platform allows you to use Infineon’s XENSIV™ DPS3xx series of high-precision barometric pressure sensors with ESPHome. This platform supports the DPS310, DPS368, and compatible variants, providing accurate temperature and pressure measurements. The I²C Bus is required to be set up in your configuration for this sensor to work.

These sensors are known for their high accuracy, low power consumption, and small form factor, making them ideal for weather stations, altitude measurement, and indoor navigation applications.

      name: "Temperature"
    pressure:
      name: "Pressure"

Configuration Variables

temperature (Required): The temperature sensor configuration.
- All other options from Sensor.
pressure (Required): The pressure sensor configuration.
- All other options from Sensor.
address (Optional, int): The I²C address of the sensor. Defaults to 0x77. The DPS3xx sensors typically use 0x77 or 0x76 depending on the hardware configuration.
operation_mode (Optional, string): Sensor operation mode. One of idle, continuous. Defaults to continuous.
update_interval (Optional, Time): The interval to check the sensor. Defaults to 60s.
id (Optional, ID): Manually specify the ID used for code generation.

Operation Modes

The sensor supports two operation modes:

continuous: The sensor continuously measures temperature and pressure at the interval specified by update_interval. This is the default and recommended mode for most applications.
idle: The sensor enters a low-power state between measurements. Useful for battery-powered applications.

Hardware Variants

The XENSIV™ DPS3xx family includes several variants with the same I²C interface:

DPS310: High-precision barometric pressure sensor with ±0.002 hPa (or ±0.02 m) precision
DPS368: Similar to DPS310 with enhanced temperature compensation
