Connectivity for Local Sensors and Actuators Using nRF24L01+
This slides cover local connectivity using nRF24L01+ and sample integration for connecting local sensors/actuators to Blynk cloud.
Connectivity for Local Sensors and Actuators Using nRF24L01+:
nRF24L01+ is a highly integrated, ultra low power (ULP) 2Mbps RF transceiver IC for the 2.4GHz ISM (Industrial, Scientific and Medical) band 2.400 - 2.4835GHz.
The Nordic nRF24L01+ integrates a complete 2.4GHz RF transceiver, RF synthesizer, and baseband logic including the hardware protocol accelerator (Enhanced ShockBurst) supporting a high-speed SPI interface for the application controller.
With peak RX/TX currents lower than 14mA, a sub uA power down mode, advanced power management, and a 1.9 to 3.6V supply range, the nRF24L01+ provides a true ULP solution enabling months to years of battery life from coin cell or AA/AAA batteries.
nRF24L01+
- ISM Frequency Band at 2.400 - 2.4835 GHz (Spacing at 1 or 2 MHz, GFSK)
- 126 RF Channels
- Air Data Rate Configurable to 2 Mbps (Options: 250 kbps, 1 Mbps)
- 4-Pin Hardware SPI
- 5V Tolerant Inputs
- 6 Data Pipe MultiCeiver for 1:6 star networks
Notes: Radio is sensitive to Noises! Make sure that the circuit (wire, solder, etc.) is stable. Anything fluxtuates is bad!
