4.Output trigger modus
Cum Pyroelectric infrared signa accepit per specillo excedit trigger limina intra specillo, comes pulsus est interius. Cum autem probe accipit tale signum iterum considerans quod accepit secundam pulsum. Semel recipit II pules in IV seconds, in specillo autem generate metum signum et Rel pin erit trigger princeps. . In addition, quod quamdiu recipi signum amplitudo excedit V temporibus trigger limine, nisi unus pulsus requiritur ad trigger in output de rel. Formam infra ostendit exemplum de trigger logica tabula. Nam multa trigger condiciones, in tene tempus de output rel computetur a novissimis valet pulsus.

VI. Sensitivity occasum
Voltage ad sensitivity in limine initus initus, quod est ad deprehendere robur in pir signum ad Pirin et Npirin inputs. Cum grounding est minimum limen of intentione, sensitivity est summa. VDD ulla intentione VDD / II erit eligere ad maximum limen, quod est infimum sensitivum occasum pro PIR signo deprehendatur, id est sensu distantia sit minimal. It should be pointed out that the infrared sensor sensing distance is not linear with the SENS input voltage, and its distance is different from the signal-to-noise ratio of the sensor itself, the imaging object distance of the Fresnel lens, the background temperature of the moving human body, the ambient temperature, the environmental humidity, and the electromagnetic interference. Tales factores formare complexu multivariate necessitudinem, id est, output non iudicari per unum indicator. In ipsa usum, ex debugging est subiectum ad mutationem. Minor sensibilitas sensibilitate pin intentione, ulterius sensu distantia. Et S918-H habet summa XXXII Sensing distantiis, et propterea sensu distantia pervenire centimeter campester. In ipsa usum, resistentia divisio modum potest ad consequi ad temperatio sensibilitatem.
