Buka ea mosebelisi bakeng sa SL-W-TRS-5.5Dx Digital Infrared Thermopile Demo Board

SLKOR Micro Semicon Co., Ltd. e na le mokokotlo oa eona oa tekheniki o tsoang Univesithing ea Tsinghua le Univesithi ea Yonsei e Korea Boroa. E etella pele nts'etsopele ea k'hamphani ka lisebelisoa tse ncha, lits'ebetso tse ncha le lihlahisoa tse ncha, 'me e tseba theknoloji e tsoetseng pele ea machaba ea lisebelisoa tsa motlakase tsa semiconductor silicon carbide pele ho nako.

 

SLKOR ke khoebo ea theknoloji e phahameng e kopanyang moralo, nts'etsopele, tlhahiso le thekiso ea lihlahisoa tsa elektroniki. E fa bareki lihlahisoa tse tšepahalang le lits'ebeletso tse tsamaellanang tsa tekheniki. Lebitso "SLKOR"E se e fetohile e tsebahalang lefatšeng ka bophara, e fana ka lihlahisoa le tharollo ho bareki ba fetang 10,000 lefatšeng ka bophara.

 

E le ho leka ho fa bareki mefuta e mengata ea lihlahisoa tse tlatselletsang, SLKOR e phatlalalitse letoto la libuka tsa mosebelisi bakeng sa liboto tsa demo tsa dijithale tsa infrared thermopile meralo ea ts'ebeliso ea lisebelisoa tsa ho metha mocheso.

 

1.1 Lebitso: Buka ea mosebelisi bakeng sa SLKOR Digital Infrared Thermopile Non-Contact Temperature Measurement Application Design Demo Board

1.2 Likopo: Lisebelisoa tse bohlale tse aparoang, lifono tse bohlale, tlhahlobo ea mocheso oa indasteri, tekanyo ea mocheso oa 'mele oa motho e sa amaneng le motho, ho lemoha le ho laola mocheso le lisebelisoa tse ling tse nyane bakeng sa ho metha mocheso oa nako e khuts'oane.

1.3 SL-W-TRS-5.5Dx Series Demo Board:

E sebelisetsoa ho lekola le ho etsa liteko tsa mefuta e fapaneng ea li-sensor. Liphetho tsa litekanyo li tla hlahisoa skrineng 'me li ka hatisoa ho software ea serial port debugging ho PC ka USB ho ea ho serial port. Tlhaloso ea konopo: Konopo e ka letsohong le letšehali ke ea ho seta bocha, 'me konopo e nepahetseng e ka laola ho qala le ho emisa ha lenaneo.

 

2. Moralo oa Hardware oa SL-W-TRS-5.5Dx Series

 

Li-chip pins li kenyelletsa phepelo ea motlakase le bese ea I2C, e nang le palo ea lipini tse 4. Mofuta o lumelletsoeng oa motlakase oa phepelo ke 2.3 - 3.6V. Sensor ka boeona e na le matla a tlaase haholo a sebelisoang. Capacitor ea 0.1uF lipakeng tsa sebaka sa phepelo ea motlakase e lekane. Haeba sensor e batla e le hole le karolo ea phepelo ea matla, ho ka nahanoa ka capacitor e eketsehileng ea 10uF ho netefatsa phepelo e tsitsitseng ea matla le ho fokotsa lerata.

 

 

 

3. Tlhaloso ea SL-W-TRS-5.5Dx Series Demo Board

 

3.1 Boto ea demo e tsamaisoa ke sokete ea Mofuta oa C, 'me motlakase oa phepelo ea motlakase bakeng sa boto ea demo ke 5V. Ha e sebelisoa, hokela boto ea demo ho PC ka Mofuta oa C, 'me u ka sheba liphetho skrineng. Haeba o hloka ho bonts'a data ka boema-kepe ba serial, o kopuoa ho kenya lenaneo la mokhanni oa WCH CH340 ebe o sebelisa software ea serial port debugging ho sebetsa. Litlhophiso tsa likhokahano tsa serial port li tjena: Sekhahla sa Baud: 9600, Likotoana tsa data: 8, Stop bits: 1, 'me ha ho cheke ea tekano.

 

3.2 Pontšo ea skrine ea boto ea demo ho tloha holimo ho ea tlase ke ka tsela e latelang: mocheso o potolohileng (tamb), sensor output voltage (vtp_cor), mocheso oa ntho (boholimo) (tobj), le mocheso oa 'mele oa motho (tbdy). Yuniti ea boleng ba mocheso o kaholimo ke °C, 'me yuniti ea motlakase ke μV. Har'a bona, litekanyetso tse tharo tsa pele ke lihlahisoa tsa pele tsa sesebelisoa. Theko ea mocheso oa 'mele e baloa ho ipapisitsoe le boleng ba mantlha ho sebelisoa algorithm ea k'hamphani ea rona 'me ke ea litšupiso feela. Basebelisi ba ka sebetsana le data ba sebelisa li-algorithms tsa bona tsa mocheso oa 'mele ho latela litlhoko tsa bona.
