Which Zigbee cluster to use for measuring Tank level using radar sensor and nRF52840

[AnkeetG]

Hi,

I am new to the zigbee development and currently going through the documents. 

My end goal is to develop a application that measures the level of a tank using radar sensor with nRF52840 using Zigbee.

I am not getting in particular which cluster/ profile to use. 

It will be very helpful if you could help me with link or document to study the same.

Thanks and regards

Hi Ankeet,

Because of public holidays in Norway I have been out of office, so I apologize for the delayed response.

There are no specific measurement and sensing or HVAC clusters that would be a good fit for your project as far as I know, but the input, output and value clusters might be a good fit. From the description of your application, you should use the Analog Input cluster.

This cluster can be used for reading the value of a measurement, as well as accessing characteristics of that measurement. The sensor measurement value will be the PresentValue attribute. There are also additional attributes in the cluster that might be of use to you, but this one is the most important one, and the one that you want to send. The PresentValue attribute supports commands that read the attribute value, as well as attribute reporting, so you can use both on your gateway to get the attribute value.

Unfortunately, this cluster is not implemented in our SDK already. However, the Binary Input cluster is, so you can take a look at the relevant files for that cluster and use the Zigbee Cluster Library Specification to see how to implement the Analog Input cluster. 

Best regards,

Marte

Hi Marte,

Thank you for your reply. I will study and try to implement your recommendation.

If any queries I will post again.

Thanks and regards
