Cabling Sensor based on NRF24L01 without PA

Arduino on carrier

Remove the 2 leds and the rebulator on the red circles to decrease the consumption

Modification to control RF module power

To reduce the consumption at minimum, add a PNP MMBT5401 and a 100R

Modification to reduce noise for RF module

Add a 10uF and 200uF 6V3 min.

ILS wiring

Box assembly

Parts :

  • Arduino carrier board described here

  • carrier for pile 3V CR123A type HALJIA

Software

The project has to be compiled and loaded with Arduino IDE

  • Change the sensor number : int temp_number = 1; // write here the Movement sensor number

  • Verify the lines :

    bool MOTION = true;

    bool SENSOR = false;
