BH1900NUX Temperature Sensor
The bh1900nux sensor platform allows you to use the BH1900NUX
(datasheet)
temperature sensor from Rohm Semiconductor with ESPHome.
The I²C bus must be set up in your configuration for this sensor to work.
# Example configuration entrysensor: - platform: bh1900nux name: "BH1900NUX Temperature" address: 0x48 update_interval: 60sConfiguration Variables
Section titled “Configuration Variables”-
address (Optional, int): Manually specify the I²C address of the sensor. Defaults to
0x48. -
update_interval (Optional, Time): The interval to check the sensor. Defaults to
60s. -
All other options from Sensor.
NOTE
The following features are not supported: ALERT pin functionality and TLOW/THIGH configuration (thermostat mode).
Configurable I²C Addresses
Section titled “Configurable I²C Addresses”The BH1900NUX provides 3 address pins (A0, A1, A2) to set the I²C address by connecting them to VCC (1) or GND (0). This allows 8 possible addresses:
| Address | A0 | A1 | A2 |
|---------|----|----|----|
| 0x48 | 0 | 0 | 0 |
| 0x49 | 0 | 0 | 1 |
| 0x4A | 0 | 1 | 0 |
| 0x4B | 0 | 1 | 1 |
| 0x4C | 1 | 0 | 0 |
| 0x4D | 1 | 0 | 1 |
| 0x4E | 1 | 1 | 0 |
| 0x4F | 1 | 1 | 1 |
