I am planning to buy a formaldehyde sensor and I would like to connect it to an Arduino Uno board (and later to a Raspberry). As far as I know, the sensor comes in a small box/bag without any other external components (e.g. amplifiers etc.). So I will end up having in my hand a sensor with two copper terminals for connection (see image below):
Is it possible to connect this to an Arduino board without having a connection scheme? If yes, where do I connect the two terminals of this sensor to the 5V, GND and the A## ports? Also, how to translate the voltage coming from the sensor to ppm (parts per million) only by having general specifications from the manufacturer and not some kind of table of conversion? Also, would I need an external component for this? If yes, which component?
I know that this question sounds very stupid, but so far I've used sensors that come with a code on Seeed Grove with a clear description and I assumed that the code is there because there is a link between the producer of a certain sensor and Groove. Thank you!
FYI: The producer writes some things about the sensor but that doesn't help me a lot:
This sensor is of the two-electrode electrochemical type, operating by the diffusion principle and as such requires no external sampling hardware. In the presence of formaldehyde gas a small direct current is produced; the sensor requires no power supply of its own but this current requires amplification to make it readable using external data collection equipment.
