1-wire temperature and voltage - Raspberry Pi Forums

-

hi

i've had great success 1-wire temperature sensor running on 10 m of phone cable.

wondered if there 1-wire sensor out there direct voltage measurement?

trying read electricity meter did using http://github.com/yfory/power recommended on forum. want see if can read clip on meter (which seems give 50hz voltage 0 -> afew v) without bother of ad converter. thinking there 1-wire voltage sensor use or use similar circuit photoresistor above diode watch capacitor fill up?

r

the ds2438z marketed "smart battery monitor" 1-wire device has 0-5v adc input can read owfs, digitemp , no doubt other software too. caveat don't mention bus master using , don't think ds2438z work gpio based driver need using "proper" master such ds9490r or 1 of our rpi2 modules.

don't know of ready made board sell humidity sensor module uses ic , if of interest supply 1 without humidity sensor on leaving ds2438z use 0-5v adc.

hello ! wrote today article on blog cpu load monitoring (using gpio , leds) on raspberry's. simple (written in little shell script), think can useful (for people want learn leds stuff on r. pi) there 5 leds turning on , off regarding cpu load: - cpu < 20%: 1 led - cpu < 40%: 2 leds - cpu < 60%: 3 leds - cpu < 80%: 4 leds - cpu < 90%: 5/5 leds - cpu >= 90%: 5 leds flashing here article: written in french, can watch youtube video , download code @ bottom of article. http://www.chteuchteu.com/2012/10/26/ra ... e-au-gpio/ if find errors in code, can post comment on article. ! up code enhancements ? raspberrypi
