1.Description
TheMerryIoTOpen/ClosesensorutilizesLoRaWAN
connectivitytocommunicatetheproximityornotofa
magnet.Theintendeduseistoplacethesensorand
magnetonseparateelementsofadoororwindowto
determineifthedoororwindowisopenorclosed.
Thesensoriscomposedoftwoparts.Themainbody
containsactiveelectronicstomeasuremagneticfields
andtransmitanychangestoaLoRaWANnetwork.The
secondpartisapermanentmagnetofsufficientfield
strengthtobedetectedbytheHallEffectsensoronthe
mainbody.

Therearealsovibrationandtiltdetectionincaseof
tampering.
Oncetheeventisdetected,thesensorwillsendan
uplinkandkeepabuzzeralarm(Optional).
