Indikátor činnosti Lambda sondy

V poslednej dobe stále viac a viac nových áut majú vo výbave, či už štandartne, alebo ako doplnok za príplatok, jednu dosť užitočnú srandičku - indikátor činnosti Lambda-sondy. Vlastne sa nejedná o nič iného, len o analógový voltmeter, ktorý má schopnosť okamžitej reakcie (ktorú nemá ani klasický ručičkový analógový voltmetr, ani digitálny), a pritom jeho spotreba na vstupe by bola natoľko mikroskopická, že by nedokázala akokoľvek ovplyvniť výstupný signál Lambda-sondy. Ak máte aspom minimálnu zkúsenosť s pájkovaním súčiastok, potom iste budete schopní túto pomôcku vyrobiť za jeden večer. Na obr. 1 je schéma celého zariadenia, postaveného na integrovanom obvode LM3914.
Zoznam súčiastok:
  1. D1 - LM3914
  2. VD1 - 1N4148
  3. VD2-VD11 - LED gulaté 2mm alebo SMD
  4. C1 - 22uF/16V
  5. R1 - 1M SMD
  6. R2,R3 - trimre 4,7k
Indikátor je napájaný z palubnej siete auta, dióda VD1 slúži ako ochrana proti prepólovaniu , kondenzátor C1 slúži k potlačeniu rušivých impulzov v palubnej sieti, trimrom R2 se kalibruje horná hranica merania (0,7-1V v závislosti na type auta pri poslednej žltej VD10, cez 1V - červená VD11 - hádam u všetkých Oplov max. provádzkové napätie signálu LS je 1V), trimer alebo pevný odpor R3 je na nastavenie jasu svietenia LED diód (miesto trimra se kludne dajú použiť obyčajné odpory). Drôt signálu od LS k indikátoru - radšej použite tienený, pričom ukostrite ho ako v mieste napojenia na signálový drôt LS, tak aj na indikátor. LEDky použite štandardné (nie tie na 12 alebo 5V), 2-3mm priemer alebo SMD, radšej rôznofarebné - napr. takto:VD2, VD3, VD4, VD5, VD6, VD7, VD8, VD9, VD10, VD11alebo hodnoty presahujúce medzné (0,1V min, 1V max) - červené; stredné - zelené, nižšie/vyššie ako stredné sa môžu použiť- žlté.Po vyrobení nakalibrujte hornú hranicu (svieti žltá VD10) na 0,95-1 V, zvolte vhodné miesto v aute, namontujte (namontovať sa dá vďaka malým rozmerom kdekoľvek) a užívajte ... Na zaseknutú alebo brzdiacu LS prídete ihneď, a okrem toho tiež budete môcť sledovať, za akých podmienok vám ECU obohacuje zmes - čo vám napríklad pomôže nájsť chybu na niektorých iných snímačoch.A ešte na záver jedna poznámka: indikátor na tejto plošnej doske má rozmer zhruba 3x3x1cm (inak, nie je problém vyrobiť ho o rozmeroch 3x1x0,5cm - ale to už vyžaduje výrobu plošáku fotografickou cestou.
