Coolant type K thermocouple module

(1/1)

Hi.... I want to use a type K thermocouple with spark plug mount on my aircooled be type 1 engine....
As coolant sensor

I have this module
AD8495 Armz Thermal K-Type Thermocouple Amplifier Analog Output Precision Module
 http://s.aliexpress.com/EZRneamU

I know I have to remove the pull up resistor on coolant analog input.... but where do I get power to feed the module.

Can I use a external power source and just connect common ground (sensor ground)

Kamuto:
you dont even need to remove pullup, just calibrate it according to your stuff

Ok thanks..... do you know about feeding the module power im not sure that is a good idea to keep putting more things on the vems 5v.

Can I use a external 5v power source and just connect common ground ?

gunni:
Yes use the analog ground and you can use an external source as long as its all from the car.
