D01 Particulate Matter Sensor

The d01 sensor platform allows you to use YYS D01 particulate matter sensors (datasheet) with ESPHome. This is a similar form factor to the PM1006 sensor, though not a direct replacement. The sensor itself is based on the GD32 MCU and outputs UART. It reports a range of 5~2500µg/m³ particle concentration, though these are the uncalibrated limits. See the filter section below for proper calculation. The effective range is 0~1000µg/m³.

Packaged D01 sensor

Communication is done using UART, so for setup, you need to have an UART bus in your configuration with the rx_pin connected to the TX pin of the D01. The baud rate needs to be set to 9600.

# Example configuration entry
uart:
  rx_pin: GPIO4 #D2
  baud_rate: 9600

sensor:
  - platform: d01
    name: "D01 PM2.5 Concentration"
    filters:
      - lambda: return (x - 5.0) * 0.4;

This implementation will passively pick up whatever the sensor reports. It automatically sends out its packets every 1.4 seconds upon receiving 5v.

Configuration variables

• uart_id (Optional, ID): Manually specify the ID of the UART Component if you want to use multiple UART buses.
• All other options from Sensor.
