This issue is for the provision of examples of CPT declarations as Sensor instance in STA.
See the SPT examples for inspiration.

Suggestion for CPT Sensor object, influenced by structure I proposed in #58 :

(
"@iot.id": 1,
"sensorType": "Ideally an entry of a controlled vocabulary to identify the type of test that is performed.",
"name": "A name given to the test that was performed. Most of the time the code / name that is used to mentionned the test",
"description": "Free text you can write to describe the test that was performed",
"metadata": "A link to a resource that propose extra information about the test",
"encodingType": "Type of encoding that is used for the metadata",
"properties": {

"testStatus" : "...",

"TestStandard": {
	"name": "...",
	"description": "...",
	"accreditingBody": "...",
	"clause": "...",
	"part": "...",
	"referenceNumber": "...",
	"version": "...",
	"other": {"propertyName": "...","value": "...","uom": "..."}	
 },
 "piezoconeType": ",,,",
 "pushRodType": ",,,",
"FrictionSleeve": {
	"area": {"value": "...","uom": "...","nilreason": "..."},
	"capacity": {"value": "...","uom": "...","nilreason": "..."},
	"other": {"propertyName": "...","value": "...","uom": "..."}	
},

	"capacity": {"value": "...","uom": "...","nilreason": "..."},
	"apexAngle": {"value": "...","uom": "...","nilreason": "..."},
	"other": {"propertyName": "...","value": "...","uom": "..."}	
},

"PorePressureElement": ( //should be able to have more than one of these
	"cellID": "...",
	"type": "...",
	"capacity": {"value": "...","uom": "...","nilreason": "..."},		
	"distanceFromConeTip": {"value": "...","uom": "...","nilreason": "..."},
	"saturationFluid": "...",
	"saturationMethod": {

		"clause": "...",

		"version": "...",
		"other": {"propertyName": "...","value": "...","uom": "..."}	
	},		
	"other": {"propertyName": "...","value": "...","uom": "..."}
)

"surfaceCapacity": {"value": "...","uom": "...","nilreason": "..."},
"tipToSleeveDistance": {"value": "...","uom": "...","nilreason": "..."},
"frictionReducerDescription": "...",
"depthToWater": {"value": "...","uom": "...","nilreason": "..."},
