Location of sensors

[David Demelier]

Hello,

I just wonder how to know the location of the sensors, I got a lot of 
them on my HP Probook laptop :

hw.acpi.thermal.tz0.temperature: 87.0C
hw.acpi.thermal.tz1.temperature: 47.0C
hw.acpi.thermal.tz2.temperature: 72.0C
hw.acpi.thermal.tz3.temperature: 59.0C
hw.acpi.thermal.tz4.temperature: 26.4C
hw.acpi.thermal.tz5.temperature: 55.0C

acpi_tz0: <Thermal Zone> on acpi0
acpi_tz1: <Thermal Zone> on acpi0
acpi_tz2: <Thermal Zone> on acpi0
acpi_tz3: <Thermal Zone> on acpi0
acpi_tz4: <Thermal Zone> on acpi0
acpi_tz5: <Thermal Zone> on acpi0

For example I know that there is two sensors on the CPU unit, and one 
one on the Wireless chipset but which one?

If you have any ideas,

Kind regards,
