Hello everyone, I am undergraduate electrical engineering student. I have a project for Analog Electronics course. I should design a system which tries to equate the heat of two stations with a controlled cooler with wirelessly received heat information. The system basicly will look like as the picture in attachments. The confising point is that I am supposed to implement two transmitters one receiver wireless communication module. And the minimum distance should be at least 1 meter. What do you think to best way for wireless communication for this project. There may be lots of choses lik using two speaker and a microphone or using two laser and an LDR. I tried to use two laser (with changable duty cycle respect to changing temperature). I can transmit that square wave to my receiver (LDR). But I could not find a solution transmitting two information to a single receiver. Any idea?
