Acroname sells a pyroelectric sensor that will work for what you need. The kit is consists of a Eltec 442-3 detector and a matched frensel lens. The kit cost is $46. I have successfully used this sensor with the MIT Handyboard, and assume it will (...) (25 years ago, 3-Apr-99, to lugnet.robotics)

This is an oppurtune time to interject my problem...I don't have the capacity to understand how you connect a sensor like this one to the rcx. The diagram on the website shows four connection points: V+, reference, gnd, and output. I only retain (...) (25 years ago, 19-Nov-99, to lugnet.robotics)

I have recently made the interface to connect the Eltec 442-3 pyroelectric sensor, using Michael Gasperi's analog interface as a reference (thanks Michael), although some minor modifications need to be made. The pyroelectric sensor works very well, (...) (25 years ago, 19-Nov-99, to lugnet.robotics)
