I'm trying to attach a Decagon EC-5 moisture sensor to a TelosB, but I'm not really sure how to attach it or configure the mote to take the readings from the external sensor.
I'm a bit confused on where to attach the excitation and the analog out wire from the sensor to the mote. I need to excite the the sensor for about 10ms before I can get a reading, which I believe means I need to connect it to the GIO. Can I connect the analog out to another GIO or does that need to go through one of the ADC pins? I'm also having trouble trying to figure out how to wire my application correctly. Can any provide an example or point me in the right direction? Part of my problem is I don't know how to initialize the configuration structure needed by the ADC to configure itself. If I only use GIOs, do I need to even do this? Any help would be greatly appreciated. - Josh _______________________________________________ Tinyos-help mailing list [email protected] https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
