Hi all, i am currently working on a project using a TSOP5038 IR receiver module in combination with a TSAL6100 IR transmitter.
The typical supply current for the TSOP5038 is 850 to 950uA depending on light conditions.
The system all works well but now i need to reduce power consumption on the IR receiver side as it will be battery powered and i need to get around 5 years battery life.
As far as the battery goes it is 3V @ 8000mA/Hr.
So as far as i can see i can turn the IR receiver on and off at say a 10% duty cycle to reduce power but then i have timing issues with the IR tx side of things as that will have a duty cycle as well as it is also battery powered.
The other alternative is to use a lower power IR receiver.
Does anyone know of such a device.
Any help would be greatly appreciated.
