chip and pinout of air/humidity sensor

[chaseadam]

Anyone know the chip and pinout of the air and humidity sensor? Usually, air/humidity sensors are just a specific IC (such as DHT22) without any logic in them. I would like to make my own instead of spending the $100.

Usually, air/humidity sensors are just a specific IC (such as DHT22) without any logic in them.

The sensor is a digital one with a bus output (as I know). The interface card is a plain communication card without measuring abilities.
It can be simply seen by the fact that there is no possibility (and no need) to calibrate the Humi/Temp probe.
