Design of 433MHz Sensor Using RFM69

We are looking to design sensor network using RFM69HW. We need the design of sensor node. You are required to design the schematic and PCB using Altium as to meet the requirements described below:

Sensor Node:

1. The sensor node will consist of RFM69HW module with ATMEGA328-SMD uC.

2. The node is to sense temperature and humidity only.

3. Choose the sensors that will be used and confirm with us.

4. It will be powered by CR2032 battery and the battery must last at-least 1 year with a reading every 5 minutes.

5. Range must be atleast 100m indoor.

6. Maximum PCB size is 30x30 mm. If it is smaller it is better.

7. Make sure ATMEGA328-SMD programming port is available for programming and firmware update.

8. The ATMEGA328 might come to us without bootloader, we need a process to upload a bootloader to it.

9. SMD antenna connector must be available as well as a port to solder helical antenna if needed.

10. All resistors and capacitors used must be 0603.

11. The PCB is 2 layers only.

12. A way to measure battery level.
