Grr, for those looking to interface this sensor and frustrated by the lack of technical documentation… note that there appears to be 10kΩ in series with the output line which it is pulled high. Good to know if you want to interface it to something other than a 5V input. For example, to drive a 3V3 input, you need to pull it to ground with 18kΩ.

Hi Heath,

Seems like an opportunity for fixing up our product page, I’ll put this on the to-do list,

Thanks for the usage info, I’m sure it’ll come in handy for future users!

Sounds good. It’s a common frustration with these types of suppliers. I guess they don’t want to scare off their target market with a schematic, but damn it would be handy for those of us with deadlines to meet!
