Hi,
I have two circuits, a transmitter and a receiver. The elements I use in the transmitter; Arduino Nano, 9V Battery , Nrf24l01 + SMA Antenna ( Included 8 pins Wireless Adapter) and 4 piece capacitive soil moisture sensor.
The elements I use in the receiver; Arduino nano, Nrf24l01 + SMA Antenna ( Included 8 pins Wireless Adapter)
I want to create a database in MySQL and draw the data I get from the buyer.
These data will have voltage and percentage humidity values.
How can I do that. What materials do I need and which circuit board I can connect?
