With my Arduino project being a success and a couple of friends asking me if they can have the circuit too, I have decided to have 50 PCB's manufactured of my circuit, however I am currently evaluating which components in my circuit should be replaced for the final version. The PCB will consist of only the needed parts of the Arduino (not much) and everything else will be scrapped (usb charging, extra pins etc).
I considered using a DHT11 for my final product however the high price in the UK means that it would be illogical, I have looked on Alibaba and I have found clones (I presume) for around 50 pence. I would rather use components from a reputable source, however I am not completely opposed to using the DHT11 from Alibaba. With regards to replacing it, I could easily measure temperature with a thermistor, however the difficulty comes when finding a humidity sensor replacement. I have not seen any for under 1 pound each (50 quantity) that have been used on an Arduino (successfully).
So does anybody know of any cheap humidity sensors that work well with the Arduino (with reasonable accuracy) and are there any reasons other than price, not to use the DHT11 in my final circuit?
Thanks in advance
