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
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
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.
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.
