 # ATMEGA328P_connectedMailBox
 
-ATMEGA328P and NRF24L01P based low power system to know when something is posted in the mail box.
\ No newline at end of file
+## What is it ?
+This system is an ATMEGA328P and NRF24L01+ based low power device to detect when something is posted in my mail box. The electronic circuit shares the same designed as the low power weather station I made enabling it to consume only 60µA when sleeping.  
+**You will also need to build a receiver station to handle the notifications. For that you can build your own or use [this design](/git/Th3maz1ng/ESP8266_dual_NRF24l01_gateway) I made.**
+
+**Check the LICENSE.md file at the root of this project for more information.**
+
+## What is this device capable of ?
+The system is able to listen for up to three events (interrupt sources).  This means that we can detect up to three different actions like :  
+* A letter was delivered in the mail box using the small letter tray.
+* A package was delivered using the door.
+* The mail was picked up using the rear door by me or a family member.
+
+**Changing the design of the event detection circuit can easily increase the number of various events that could be detected**
+
+## Power consumption :
+* The device consumes around 60µA when sleeping (ie : waiting for an event to happen).
+* The device consumes around 13mA for a very short period of time when transmitting a RF packet after an event was detected.
+* The current design is using a 2000mAh LiPo battery which should last for at least four years of every day use. **/!\ I may update the design to add a solar pannel like I did for the weather station.**
