Abstract:
In thispaper,we presenta detailed descriptionofamini pyranometer8-bit2-input.This device
isdedicated to the measurementof incident solar radiationdirectlyin thevisible and nearinfrared
(withtwo photodiodesbroad-spectrum,respectively, aBPW21, andBPW34.This deviceis
oftencoupledwithanautomaticregister(datalogger), to establish ataking of measurementsfor a long
period, tomakeagood dimensioningof aphotovoltaicsystemon a regionundersolarelectrification. The
realizationof this circuit isbased on the useof the smallestmicrocontroller8-bit existingin today's
market, a6-pin PIC10F222onlythebaselinerangeofMicrochip.This microcontrolleris responsible
forall functions providedin thisdevice (measures, controlsandmanagement of aLUTfor each sensorat
stake),throughspecialized integratedmodulessuch asanalog to digital converter8-bit twochannelmeasurementandone8-
bittimerwithpre-divider.It’s very lowpower consumption (<170μA
under2V, 4 MHz) makes itparticularly recommended forthedesign and constructiondevice oflongrangeenergy,
particularly,products and accessoriesdedicated to the measurement ,thecontrol and
regulationin the variousfields ofsolar energy
