Re: IR sensor heating


Thank you for your answers.
The option of using a relay is interesting even manually and easy to implement
In my research how to save one wire (to connect the relay). i have a basic question for you, can i use the 12 V- wire (from the wind sensor) for another purpose and use the 5V- instead ? can the wind sensor work with a 12V+ and 5V- ? Since all the negative wires are connected together it should be possible ?
