Here is a PTC-based fire alarm circuit that you can follow:
By the way, you can also consider using a temperature sensor+arduino instead:

Hello, I think you can contact the manufacturing company. Contact details are given at the end of the datasheet:

You can start with some basic projects. Maker pro has many good blogs and tutorials like this: https://maker.pro/allthingstalk/projects/a-guide-to-led-emergency-light-circuit-with-ldr
The manual is here but couls not find a schematic.

Here is a tutorial on UART communication between the Raspberry Pi Pico W and the Arduino UNO: https://electrocredible.com/raspberry-pi-pico-serial-uart-micropython/
You can use a logic level converter, as shown here, too.
I also believe the value is right. The size looks as same as tantalum caps available at different websites:
