Low power node - ATMega328p standalone based environment sensor

low_power_sensor.ino is dedicated to outside house measurement it measures humidity, temperature, hygrometry and battery voltage Tutorial: http://1technophile.blogspot.fr/2016/08/low-cost-low-power-6ua-garden-433mhz.html

low_power_sensor_inside.ino is dedicated to inside house measurement it measures humidity, temperature and battery voltage Tutorial: http://1technophile.blogspot.fr/2016/12/low-cost-low-power-room-sensor-with.html

This program enables to send sensor data with low power:

• send sensor data to a 433Mhz gateway
• with 3 AA batteries measured at 5V the current consumption in sleep mode is around 6uA
