    I am using an IR sensor module (https://www.amazon.com/HONG111-Infr...c-Reflection/dp/B06XKN15TT?ref_=fsclp_pl_dp_3) for my automatic dispenser system. Now, while mounting the IR sensor module in my enclosure, which material can I use to cover the IR sensor module which can allow the IR light to pass through below the glass for the hand to get detected.

    I wonder what material is used to cover the IR sensor used in restroom flush systems.[​IMG]

    Typically a plastic transparent to infrared is used (black or very dark red to the naked eye). See e.g. here or here.
