The first thing to check is that the crickets are generating distance estimates in the same units in which you are measuring. From the top of my head I can remember that crickets output distance estimates in centimeters and some other units. The second thing is that they are very directional and produce good estimates only when the ultrasound transducers are facing each other.
Hope it helps. On 5/6/07, Yusuf Ozturk <[EMAIL PROTECTED]> wrote:
Greetings, We are implementing an indoor location estimation solution using the xbow cricket kits with the firmware loaded by xbow and the readings are off the chart. The distances and time of arrival readings at the listener are varying too much and beyond limit. Does anyone out there has experience with cricket motes and can give us at least an indication of whether they work and what do we need to get them to report correct readings Regards Yusuf _______________________________________________ Tinyos-help mailing list [email protected] https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
