Plugin: python.d.plugin Module: am2320
This collector monitors AM2320 sensor metrics about temperature and humidity.
It retrieves temperature and humidity values by contacting an AM2320 sensor over i2c.
This collector is supported on all platforms.
This collector only supports collecting metrics from a single instance of this integration.
Assuming prerequisites are met, the collector will try to connect to the sensor via i2c
The default configuration for this integration does not impose any limits on data collection.
The default configuration for this integration is not expected to impose a significant performance impact on the system.
Metrics grouped by scope.
The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
Per AM2320 instance
These metrics refer to the entire monitored application.
This scope has no labels.
There are no alerts configured by default for this integration.
Sensor connection to a Raspberry Pi
Connect the am2320 to the Raspberry Pi I2C pins
Raspberry Pi 3B/4 Pins:
- Board 3.3V (pin 1) to sensor VIN (pin 1)
- Board SDA (pin 3) to sensor SDA (pin 2)
- Board GND (pin 6) to sensor GND (pin 3)
- Board SCL (pin 5) to sensor SCL (pin 4)
You may also need to add two I2C pullup resistors if your board does not already have them. The Raspberry Pi does have internal pullup resistors but it doesn't hurt to add them anyway. You can use 2.2K - 10K but we will just use 10K. The resistors go from VDD to SCL and SDA each.
Install the Adafruit Circuit Python AM2320 library:
sudo pip3 install adafruit-circuitpython-am2320
The configuration file name for this integration is
You can edit the configuration file using the
edit-config script from the
Netdata config directory.
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config python.d/am2320.conf
There are 2 sections:
- Global variables
- One or more JOBS that can define multiple different instances to monitor.
The following options can be defined globally: priority, penalty, autodetection_retry, update_every, but can also be defined per JOB to override the global values.
Additionally, the following collapsed table contains all the options that can be configured inside a JOB definition.
Every configuration JOB starts with a
job_name value which will appear in the dashboard, unless a
name parameter is specified.
|update_every||Sets the default data collection frequency.||5||no|
|priority||Controls the order of charts at the netdata dashboard.||60000||no|
|autodetection_retry||Sets the job re-check interval in seconds.||0||no|
|penalty||Indicates whether to apply penalty to update_every in case of failures.||yes||no|
|name||Job name. This value will overwrite the ||no|

To troubleshoot issues with the
am2320 collector, run the
python.d.plugin with the debug option enabled. The output
should give you clues as to why the collector isn't working.
Navigate to the
plugins.ddirectory, usually at
/usr/libexec/netdata/plugins.d/. If that's not the case on your system, open
netdata.confand look for the
Switch to the
sudo -u netdata -s
python.d.pluginto debug the collector:
./python.d.plugin am2320 debug trace
