Three-way wireless remote control switch based on NRF24L01-transmit

Overview

1. Controlled by Atmel Mega 168P chip, written in Arduino C language

2. With 3-digit address code selection (the channel can also be modified in the program)

3. Can be placed in the 86 junction box, size 58mm*54mm

4. The main control chip can be changed to ESP12 and the WIFI control function can be added

5. Powered by 3.7v lithium battery, rechargeable,

6. Added hardware power-saving function, which only supplies power to NRF24L01 when it needs to transmit signals. It is more environmentally friendly to use 100mAH polymer lithium battery, and the theoretical power supply time is up to half a year.

Because I didn’t take photos specifically for this project, I took them from the family photo of the Internet of Things project (lower right) . The problem lies in the power supply method. Maybe I shouldn't use NRF24L01 as a communication module at all, because it consumes too much power and the 100mAh lithium battery cannot support it at all. The source code of the successful test will be made public later as the sample code of NRF24L01 for your reference. Family portrait.jpg
