Basic prototype of node working!

A project log for Garden_automation_and_sensor_network

A network of low power sensor nodes in the garden, and possibly some automation as well.

A few days ago I got a small node running on an MSP430G2452 mcu, sending it's internal temperature sensor data of the air via a nRF24L01+ module. The temperature measurements are using the internal ROM calibration data for better accuracy.

The code can be found here:

The reciever is a MSP430 launchpad with MSP430G2553 running an Energia sketch that parses the temperature value from the packet and prints the results over UART to the computer via an FT232BL USB to serial converter ic breakout.
