I’d like to use the Argon to monitor the state of my house doors. My goal is to do it in a way where the battery (figure a 2000mAh) will last around 5-6 months. If all I did was have the Argon check the state of the door and then go into hibernate for 5 minutes, this shouldn’t be too hard to do. When turned off the power draw is minimal.
The problem there is that I also want to know as soon as the door is opened (reed switch goes from closed to open). Lets say with a latency of 1-2 seconds. I was thinking of using the RST pin such that when the switch opens the RST pin is brought to high. But I haven’t figured out a way to do that which doesn’t draw power itself.
I could shut all the communications down and let it sleep for 1 second between checking the door status, but even then I don’t think I’ll get more than a few days out of a battery.
Any thoughts on how this could be done?
Any thoughts on how to do the circuit?
