XIDIBEI XDB401 Pressure Sensor

The XIDIBEI XDB401 is available with either I²C or analog output; this ESPHome platform supports the I²C variant. The sensor is sold in several maximum pressure ranges (1 to 100 bar), see pressure_range_bar below. Pressure is reported in Pascal (Pa) and temperature in °C.

Configuration variables

• temperature (Optional): The measured temperature in °C. All options from Sensor.
• pressure (Optional): The measured pressure in Pascal (Pa). All options from Sensor.
• pressure_range_bar (Optional, int): The maximum pressure range of your sensor model in bar. One of 1, 2, 5, 10, 20, 50, 100. Defaults to 10.
• address (Optional, int): Manually specify the I²C address of the sensor. Defaults to 0x7F.
• update_interval (Optional, Time): The interval to check the sensor. Defaults to 60s.
