PIC18F252 Microcontroller & nRF24L01+ : Wireless Transmitter 

Glad you enjoyed it!

Hi, since only digital I/O is used, it can be done with any other mcu which has sufficient ports.

And if i want to make a device which requires both tx & rx but again tx should be compact what sensor and tx device i should use?

Not sure if i got your question correct. In the configuration that I showed, the mcu-nrf module can either be tx or rx.(in this video it’s tx, however you can use the receiver code I made in msp430 and port it to PIC similarly). Also there are no sensors in this setup, not sure what you mean by that.
