Awọn microOSYSTEMS ti o tẹle Smart Fan HAT fun Rasipibẹri Pi 

Apejuwe gbogbogbo

Fan Smart jẹ ohun ti o wuyi julọ, iwapọ ati ojutu itutu ilamẹjọ fun Rasipibẹri Pi rẹ. O ni ifosiwewe fọọmu ti Rasipibẹri Pi HAT. O gba awọn aṣẹ lati Rasipibẹri Pi nipasẹ wiwo I2C. Ipese agbara igbesẹ kan yi iyipada 5 Volts ti a pese nipasẹ Rasipibẹri Pi si 12 Volts, ni idaniloju iṣakoso iyara to peye. Lilo awose iwọn pulse, o fi agbara fun afẹfẹ kan to lati ṣetọju iwọn otutu igbagbogbo ti ero isise Rasipibẹri Pi.
Fan Smart ṣe itọju gbogbo awọn pinni GPIO, gbigba eyikeyi nọmba ti awọn kaadi lati wa ni tolera lori oke Rasipibẹri Pi. Ti kaadi afikun miiran ba ni lati tuka agbara, Smart Fan Atẹle le ṣafikun si akopọ.

Awọn ẹya ara ẹrọ

• 40x40x10mm àìpẹ pẹlu 6 CFM airflow
• Ipese agbara 12V ti o ga soke fun iṣakoso iyara àìpẹ deede
• Alakoso PWM ṣe atunṣe afẹfẹ lati tọju iwọn otutu Pi nigbagbogbo
• Fa kere ju 100mA ti agbara
• Ni kikun stackable faye gba fifi miiran awọn kaadi to rasipibẹri Pi
• Nlo nikan ni wiwo I2C, fi oju ni kikun lilo gbogbo GPIO pinni
• Super idakẹjẹ ati lilo daradara
• Gbogbo ohun elo iṣagbesori pẹlu: awọn iduro idẹ, awọn skru ati eso
• Laini aṣẹ, Node-RED, Awọn awakọ Python
