# Weight Sensor
Continuous weight measurement using the Aranet Weight sensor enables real-time monitoring
of various plant growth factors, including biomass increase, plant weight, water addition, and
drainage weight. Both the 50 kg and 100 kg versions operate wirelessly and are powered by a
single AA battery. For more comprehensive insights, consider combining multiple weight
sensors to detail processes within the greenhouse.
#### Use cases
Measurements allow us to foresee problems, which can result in a slowdown in production and
plant overload. Weight sensors can also be used to gain insights about fruit weight, evaluate
average fruit growing days, and assess leaf weight on the plant. Data enables the analysis of
biomass distribution by examining weight changes at fruit and leaf harvest, as well as tracking
weekly yield and other parameters.
Combine multiple weight sensors and track weight for several parameters to obtain more
detailed information about processes in the greenhouse. The Aranet Cloud platform allows the
creation of virtual sensors to calculate the difference or sums between the measurements.
It is possible to use a weight sensor for a specific, custom weighing solution, more available here: [Custom Weighing Solutions for Horticulture](/pro-series-sensors/pro-series-sensors/weight-sensor/custom-weighing-solutions-for-horticulture.md)
#### Good practice recommendations
To track biomass gain, fruit load, etc., install a Weight sensor directly at the truss.

In case several weight sensors are used for
\
more precise plant growth insights, feel free
to create a frame with several weight
sensors, as well as install the weight sensors
for the whole plant section as a reference
section for a greenhouse.

The large water content in plants and fruits is
the primary factor contributing to the
weakening of the radio signal if sensors or the
base station are positioned too low. The sensor
has an extended wire to a transmitter - position
the transmitter (white body approximately one
foot or 30 centimeters above the expected
maximum height of the plants.

#### Specific notes
{% tabs %}
{% tab title="Using Web GUI" %}
To reset the zero offset of weight (tare), click on the TARE button. The last measured tared and (untarred
weight), as well as the date and time of the last tare event, will be indicated.
By default, the graph of the Weight Sensor will display
measurements of a tared weight. To display the untarred
weight in the graph, click the Tune button and
tick the “Show” box.
{% endtab %}
{% tab title="Using Aranet Cloud" %}
To tare the weight measurement, go to the base station management feature in the Aranet Cloud
interface. Click on “Add & Manage Sensors,” select your weight sensor, and then click on the
TARE button.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://help.aranet.com/pro-series-sensors/pro-series-sensors/weight-sensor.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
