I cameĀ  across these on ebay.

I was wondering if anyone has tried to put an IR sensor like a Vishay TSOP 38238 sensor directly on a serial to TTL adapter like this. ItĀ  would seem that the Vishay TSOP38238 might work directly without additional components as it will take 5 Volts I am looking for a solution I can use ion quantity without making homebrew adapters. I think the homebrew design became popular because TTL adapters like this were not so available at a low price.

Thanks in advance
