Thankfully this has a diode to prevent connecting it backwards. The diagrams I found online were incorrect. The pcb labels are under the plastic dome, so double check by removing it before connecting. Other than that, it works.

Módulo de sensor IR perfeito do projeto... Um pouco maior do que eu esperava (tamanho da unha do polegar), mas bem construído e com uma configuração fácil, tão cheia de funcionalidade.

Perfect project IR sensor module ... slightly larger than I expected (size of thumb nail) but well constructed, and with easy setting, so packed with functionality.
