Lawn Mower Blade to Custom Knife
ATTiny EMF Detector
Hi Rudy, it's a nice project. I'm managing to make something similar with NodeMCU as a cheaper solution for such a simple task. However I'll give you a tip about how to check the door position and movement. You can use ultrasonic proximity sensor HC-SR04 to check how far is the door from the sensor and if it changes its position.

Well it's helpful to know that but AM2320 is NOT a DHT series sensor so it won't work with it. But thank you for your note. If I choose to use DHT sensors I'll definitely gonna try it.

Yes you can but with some additional hardware. There are two things you can try: 1. You can use an i2c multiplexer module which lets you to use up to 8 i2c sensors with the same address. You can find one here: http://www.ebay.com/itm/192035992071 2. You can use a logic switch to power up only one sensor at a time as described in this post: https://blogs.msdn.microsoft.com/laurelle/2012/02/24/using-2-identical-i2c-device-on-the-same-i2c-bus/ I prefer the first solution as it's cheap and stable. I'll be happy if you try and reply with the results. Good luck! :-)
