+> THIS MODULE IS OBSOLETE.
+> USE THE PYTHON ONE - IT SUPPORTS MULTIPLE JOBS AND IT IS MORE EFFICIENT

+> Unlike the python one, this module can collect temperature on RPi.
+
+# sensors
+
+The plugin will provide charts for all configured system sensors
+
+> This plugin is reading sensors directly from the kernel.
+> The `lm-sensors` package is able to perform calculations on the
+> kernel provided values, this plugin will not perform.
+> So, the values graphed, are the raw hardware values of the sensors.
+
+The plugin will create netdata charts for:
+
+1. **Temperature**
+2. **Voltage**
+3. **Current**
+4. **Power**
+5. **Fans Speed**
+6. **Energy**
+7. **Humidity**
+
+One chart for every sensor chip found and each of the above will be created.
+
+### configuration
+
+This is the internal default for `/etc/netdata/sensors.conf`
+
+```sh
+# the directory the kernel keeps sensor data
+sensors_sys_dir="${NETDATA_HOST_PREFIX}/sys/devices"
+
+# how deep in the tree to check for sensor data
+sensors_sys_depth=10
+
+# if set to 1, the script will overwrite internal
+# script functions with code generated ones
+# leave to 1, is faster
+sensors_source_update=1
+
+# how frequently to collect sensor data
+# the default is to collect it at every iteration of charts.d
+sensors_update_every=
+
+# array of sensors which are excluded
+# the default is to include all
+sensors_excluded=()
+```
