I need your suggestion / advice (help) to complete my first project with Arduino as a beginner. I’ve created a human detector with PIR sensor and works perfectly. After detecting movement the LED turning on for a few seconds; now what I want to do is the following: After detection the detector must send signal from A point to B via some signal receptor of WIFI but no cable. Could you suggest me please, what can I use to do that?
Many thanks in advance.
