Hi Campbell, There's no guaranteed method of knowing which "beam" is being broken since (i) the beams are not really sharp beams but instead a fuzzy field-of-view, (ii) the beams are an artifact of optics, not electronics, and (iii) when a person walks by the sensor, the person's path may not intersect all of the "beams" for a given sensor. You could estimate the beam in software with some but I suspect that you'd find a non-negligible rate of misclassification.

hi , who does have the experience in accomplishing some detection application with MSP410?? Now when the PIR sensor detects some body , the sensor just gives us one of the 4 quad values.ex quad 1 detected. and i want to know could we get the sub-beams info ??ex. quad1 beams 2 detected?? and how ?? best regards _______________________________________________ Tinyos-help mailing list [email protected] https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
