Kev txhawb siab: Kuv xav siv lub roj teeb uas siv lub koob yees duab Raspberry Pi los thaij duab ib hnub ib hnub sab nraum zoov los tsim cov vis dis aus ntev-sijhawm. Kuv daim ntawv thov tshwj xeeb yog sau cov av npog cog kev loj hlob tuaj rau lub caij nplooj ntoo hlav thiab lub caij ntuj sov tuaj.

Kev Nyuaj Siab: Tsim qis Raspberry Pi lub zog tswj tam sim no kom ntseeg tau lub roj teeb ntev.

Kuv Cov Tshuaj: Kuv siv lub tswb tsoo lub tswb, Attiny85 Circuit & Pimoroni OnOff shim kom txiav lub zog kom tag rau Raspberry Pi thaum tsis siv. Thaum Attiny85 thiab lub tswb moos tseem ua haujlwm nyob rau hauv hom tos, tam sim no kos tsuas yog 5 microAmps. Ob lub roj teeb AAA siv hluav taws xob ob qho tib si Attiny thiab lub tswb moos, thaum lub USB fais fab nyiaj hauv tuam txhab txhawb Pi.

Kev Ua Haujlwm Yooj Yim: Thaum lub tswb nrov tawm mus nws ua rau tsaug zog Attiny Circuit, uas tom qab ntawd qhia Pimoroni OnOff shim kom siv lub zog los ntawm USB lub txhab nyiaj fais fab rau Raspberry Pi. Tus Pi ua tiav cov ntawv sau-ntawm-khau raj (thaij duab). Tom qab lub sijhawm txaus dhau los (60 vib nas this hauv kuv daim ntawv thov), Attiny Circuit rov qhia dua Pimoroni OnOff shim thiab tom qab ntawd Attiny nkag mus pw hom. Raws li lub teeb liab los ntawm Attiny, Pimoroni OnOff shim ua haujlwm Pi kaw qhov kev hais kom ua, thiab tom qab Pi kaw txheej txheem ua tiav, txiav lub zog los ntawm USB lub txhab nyiaj rau Raspberry Pi.

Kuv ntsuas tam sim no siv xov tooj cua Shack RS-232 Multimeter (22-812) thiab ua khub Meter Saib software. Tsis yog tsiaj nyaum xaiv, tab sis nws yog qhov kuv muaj.

Kev ntsuas ntsuas tam sim no los ntawm ob lub roj teeb AAA zog Attiny85 pawg thawj coj thiab lub tswb nrov

Rau "series txuas" multimeter, Kuv tau siv roj teeb dummy thiab 3 VDC lub rooj zaum lub hwj chim (saib daim duab). Saib daim duab ntawm kev ntsuas tam sim no thaum lub sijhawm "nquag" (pib nrog lub tswb ceeb toom - xaus nrog Attiny85 rov qab mus rau hom pw tsaug zog). Tsis-tswb kos yog tas li 0.0049 mA. Ntsiab lus -

Lub Sijhawm Ua Haujlwm = 78 vib nas this

Lub Sijhawm nquag Tam sim no = 4.85 mA

Tsis Tswb Tam Sim No = 4.9 microA (0.0049 mA)

Kuv xam qhov nruab nrab niaj hnub tam sim no ntawm 0.0093 mA los ntawm ob lub AAA (750 mAh/txhua) txiav txim siab txog kev pw tsaug zog thiab hom kev ua haujlwm, thiab kev xav txog lub roj teeb lub neej> 8 xyoo siv txoj hauv kev no.

Kev ntsuas ntawm PI tam sim no kos los ntawm USB lub txhab nyiaj. To "series txuas" multimeter Kuv tau siv qhov hloov pauv usb cable (saib daim duab). Saib daim duab ntawm kev ntsuas tam sim no thaum lub sijhawm "nquag" (PI boot up - PI kaw). Thaum lub sijhawm tsis ua haujlwm Pimoroni ONOFF shim txiav lub zog rau Pi, yog li tam sim no kos ~ xoom. Ntsiab lus -

Lub Sijhawm Ua Haujlwm = 97 vib nas this

Lub Sijhawm nquag Tam sim no = 137 mA

Piv txwv tias yog 11200 mAh lub txhab nyiaj fais fab theoretical tus naj npawb ntawm lub sijhawm ua haujlwm nquag yog> 3000.

Kev Xeem Roj Teeb Sij Hawm

Kuv tau tswj hwm PI ib ntus nrog Arduino UNO tau npaj rau kev caij tsheb kauj vab nrawm - lub sijhawm ntawm lub tswb nrov yog 2 feeb piv rau 24 teev ib txwm.

Kuaj #1: 11200mAh fais fab nyiaj hauv tuam txhab. Pib thaum 10 teev tsaus ntuj thiab kuv nres ntawm 1 teev tsaus ntuj hnub tom qab. Cov txiaj ntsig: 413 cov duab thaij, 3 ntawm 4 qib LEDs tseem nyob ntawm qhov kev xeem kawg.

Kuaj #2: 7200mAh fais fab nyiaj hauv tuam txhab. Pib thaum 7:30 teev tsaus ntuj thiab kuv tau nres ntawm 4: 30PM hnub tom qab. Cov txiaj ntsig: 573 cov duab thaij, 2 ntawm 4 qib qib LED tseem nyob ntawm qhov kev xeem kawg.

Xaus: Kuv ntseeg tias cov txiaj ntsig saum toj no qhia tias tsawg kawg ib xyoos kev ua haujlwm siv 1 daim duab ib yam.

Pom zoo:
