I'm trying to measure the voltage of the batteries of my micaz nodes.
When using the VoltageM component, I'm always getting values like Vbat= 3901, 4638, 4892, 5261, 5398, 5351, 5445, 5398 .... -> So, 5,3 Volt for two AA batteries?? Seems very strange...
When printing the raw 10-bit ADC value (so without the conversion (in the VoltageM component) Vbat = Vref * 1024/ADC_Count) the ADC_Count = 315, 258, 243, 230, 227, 229, 225,...
So in order to get more realistic values like Vbat = 2900mV: the ADC_Count should be around 430...
Everything is mapped right, I'm measuring the ADC-channel 30 for micaz...
Anyone knows what is wrong? (the same problem has already been posted a month ago, http://mail.millennium.berkeley.edu/pipermail/tinyos-help/2006-April/016227.html)
Greetings,
Robin
