Need to increase more fields in Free ThingSpeak account?

In my experiment, I need more field in a single channel to collect parameters. How can I increase more fields in Free ThingSpeak account?

You can use the status and location field, use multiple channels per device, or pack more inforamtion into a single field (they hold up to 255 characters). You can use custom visualizations to unpack the field values, since the standard field plots wont interpret multiple values.

Dear Christopher Stapels,

Thank you for your answer. I have the exact same question. In total I need to visualize 12 parameters out of 6 different sensors. The outputs of the sensors are as follows.

Sensor 1: one parameter

Sensor 2: one parameter

Sensor 3: one parameter

Sensor 4: three parameters

Sensor 5: four parameters

Sensor 6: two parameters

Is it possible to dedicate each sensor to a field? For example:

Field 1 - Sensor 1: so field 1 will only demonstrate that one parameter

Field 2 - Sensor 2: so field 2 will only demonstrate that one parameter

Field 3 - Sensor 3: so field 2 will only demonstrate that one parameter

Field 4 - Sensor 4: so field 2 will demonstrate that three parameters in one graph

Field 5 - Sensor 5: so field 2 will only demonstrate that four parameters in one graph

Field 6 - Sensor 6: so field 2 will only demonstrate that two parameters in one graph

How can I achieve this?

If possible is there any downside to this?

Additionally, as I saw from your previous response, you said a single field holds up to 255 characters. What does it mean? What does custom visualizations to unpack the field values mean?

Thank your for your interest.
