Actually I didn't give that much thought, I will verify that. Thank you for pointing that out.Can you verify that the MCU can wakeup from low power sleep in a couple of milliseconds? Which MCU are you using?
I am using pic16f616.

I have done some test today, that's how I do it:Can you verify that the MCU can wakeup from low power sleep in a couple of milliseconds? Which MCU are you using?
I have tested this one, the range is too short. I am hoping to get the same distance as the Vashey IR Receiver.@bug13
Maybe something simple like this just to wake it up?

I was afraid of that.I have tested this one, the range is too short. I am hoping to get the same distance as the Vashey IR Receiver.
The low power IR detection circuit is where I am hoping to get some help with. See my post #11Would you be ok in having to use two pulses to get the command across? I.e. the low power section will activate if 38khz is detected, wake up the cpu, and then the cpu will receive the second button to do the proper function?
That was a project we done a long time ago, it was a success! Need more details about your project, but I think 6-7 meters is definitely doable. Have PMed you.Hi!
I know this is a super old thread but I've got a product we're moving into the 2nd generation and need a super low power usage IR solution that will "wake up" the MCU. You seem like you know what you're doing and learned a lot. are you open for some consulting to help guide our engineers on what you found?
I'm Jamie <e-mail address snipped> Hope to hear from you!
MOD NOTE: Please respond here or PM Jamie if you think you can help.
Using MSP430, runing on LPM3, power the Vashey IR receiver on a duty cycle of about 7.6%. this drop my standby current from ~350uA to ~35uA (IR receiver + MCU). The duty cycle is limited by the slow response of the IR receiver module and the 9ms NEC IR protocol lead code I am using.
PS: the working distance is about 6-7 meters.
Send me a PM with your email, and we can go from there.Hi, this project is exactly what I'm looking for! Can you share some details or maybe are you interested in a collaboration?
I am also really interested in how you solved your problem because I am facing the exact same difficulties at the moment. Could you share some information (also over PM if prefered)?Send me a PM with your email, and we can go from there.
