The initial request was related to noise appearing on all signals recorded, using a TSOP1738 on a 3V3 ESP8266/NodeMCU.
The initial solution was:
The TSOP1738 (family) can be powered between 4.5V->5.5V only. The problem was that it was powered from 3V3. The solution was to use a more modern IR receiver, which can also work at a much lower voltage.
The follow-up issue is below:
Ok ..... I think yeah. I replaced the reciever and setup on arduino. Working fine now.
I am able to detect few codes but while working with AC Codes i faced another issue. The Type of code detected by the software is ELECTROLUX192_AC. But in arduino ir remote library we dont have that protocol so i am not sure how to fire this protocol back using IR LEDs. So is there anyway i can use these protocols on my arduino to fire back ?
