Ultra-Low-Power Sensor Hub Using nRF24L01 Modules

Presented here is an ATmega328P microcontroller-based ultra low power sensor hub using nRF24L01+ radio frequency (RF) transceiver modules having transmitter and receiver units. The transmitter sends humidity and temperature values of a place to the receiver kept at a remote location for display on an OLED module. The nRF24L01+ module used in the receiver unit is a 2.4GHz transceiver suitable for ultra-low-p ...
