I've used this solution in past and it works very well.
Actually I've added an ExternalList, so the available sensors can be discovered by instance discovery.

Line in Agent config file:
ExternalList = OpenHardwareMonitor.Sensors:powershell -NonInteractive -Command "& { get-wmiobject -namespace root\OpenHardwareMonitor -query 'select * from Sensor' | foreach { $$_.InstanceId } }"

WMI.Query(root\OpenHardwareMonitor,"select * from Sensor where InstanceId='{instance}'",Value)

SensorType = AgentReadParameter($node, "WMI.Query(root\OpenHardwareMonitor,\"select * from Sensor where InstanceId='" . $1 . "'\",SensorType)");
Name = AgentReadParameter($node, "WMI.Query(root\OpenHardwareMonitor,\"select * from Sensor where InstanceId='" . $1 . "'\",Name)");
Identifier = AgentReadParameter($node, "WMI.Query(root\OpenHardwareMonitor,\"select * from Sensor where InstanceId='" . $1 . "'\",Identifier)");
return %(SensorType == "Temperature", $1, Name . " [" . Identifier . "]");
