A program to read data from sensors using the go-sensors libraries and reporting with Prometheus.
By default, no sensors are enabled. When deploying with Balena, set the *_ENABLED environment variables for your sensors to start reading from them.
| Environment variable | Description | Default value | Valid values |
|---|---|---|---|
EXPORTER_METRICS_SERVER_ADDR |
Address (host:port) to which to bind for hosting the Prometheus metrics server | :9000 |
Any valid host and port combination; host may be empty to bind on all available addresses |
EXPORTER_LOG_LEVEL |
Determines the amount of detail included in the log output | warn |
fatal, error, warn, info, debug |
EXPORTER_ASAIRAHT10_ENABLED |
Enable the Asair AHT10/AHT20 temperature and relative humidity sensors | false |
true, false |
EXPORTER_ASAIRAHT10_I2C_BUS |
Number of I2C bus on which to find the sensor | 1 |
Any valid I2C bus available to the device. On Raspberry Pi, I2C buses 0 and 1 are typically configured on the GPIO header |
EXPORTER_ASAIRAHT10_I2C_ADDR |
7-bit I2C address of the sensor | 0x38 (dec 56) |
A valid 7-bit I2C address. May be specified in decimal or in hexadecimal when prefixed with 0x |
EXPORTER_CUBICPM1003_ENABLED |
Enable the Cubic PM1003 particulate matter sensor for measuring air quality | false |
true, false |
EXPORTER_CUBICPM1003_DEVICE_PATH |
Path or name of block device through which to communicate with the sensor's UART interface | /dev/ttyAMA0 |
Any valid path to a block device where the sensor is connected. Depending on the Raspberry Pi model, there may be two or four UARTs configured on the GPIO header. |
EXPORTER_PLANTOWERPMS5003_ENABLED |
Enable the Plantower PMS5003 particulate matter sensor for measuring air quality | false |
true, false |
EXPORTER_PLANTOWERPMS5003_DEVICE_PATH |
Path or name of block device through which to communicate with the sensor's UART interface | /dev/ttyAMA0 |
Any valid path to a block device where the sensor is connected. Depending on the Raspberry Pi model, there may be two or four UARTs configured on the GPIO header. |
EXPORTER_SENSIRONSCD30_ENABLED |
Enable the Sensiron SCD30 gas sensor | false |
true, false |
EXPORTER_SENSIRONSCD30_I2C_BUS |
Number of I2C bus on which to find the sensor | 1 |
Any valid I2C bus available to the device. On Raspberry Pi, I2C buses 0 and 1 are typically configured on the GPIO header |
EXPORTER_SENSIRONSCD30_I2C_ADDR |
7-bit I2C address of the sensor | 0x61 (dec 97) |
A valid 7-bit I2C address. May be specified in decimal or in hexadecimal when prefixed with 0x |
EXPORTER_SENSIRONSGP30_ENABLED |
Enable the Sensiron SGP30 gas sensor | false |
true, false |
EXPORTER_SENSIRONSGP30_I2C_BUS |
Number of I2C bus on which to find the sensor | 1 |
Any valid I2C bus available to the device. On Raspberry Pi, I2C buses 0 and 1 are typically configured on the GPIO header |
EXPORTER_SENSIRONSGP30_I2C_ADDR |
7-bit I2C address of the sensor | 0x58 (dec 88) |
A valid 7-bit I2C address. May be specified in decimal or in hexadecimal when prefixed with 0x |
