Bien livré avec une pile AAA et les 2 adhésifs double face pour fixer le détecteur et l'aimant. Pour changer la pile, il n'y a aucune vis à dévisser, c'est seulement clipsé. Le plastique est de bonne qualité, le produit bien fini. L'antenne d'émission à l'intérieur fait toute la longueur du détecteur. Il n'envoie un signal 433 MHz que sur ouverture. Il n'y a aucun signal pour indiquer une fermeture ou confirmer l'état régulièrement. L'identifiant reste le même quand on change la pile. Quand la pile est faible, il n'envoie aucun signal particulier, mais la LED clignote régulièrement pour indiquer le problème. La distance de détection est la même quelque soit l'état de la pile et est d'environ 1 à 1,5 cm. Le code de détection est de ce type : 20;1C;EV1527;ID=0ad33b;SWITCH=0e;CMD=ON;

Q: is it send two signals (open/close)

Asked by trottiermarcandre on 2019-08-04 06:21:16

boism No. It send ONLY one opening signal. There is no signal for the closing, and no repetitive signal to confirm it's still opened. The signal for opening looks like "0e". This is waht I see: 20;52;EV1527;ID=0ad33b;SWITCH=0e;CMD=ON; The ID remains the same when battery is changed.

De très bonne apparence cette pince est fonctionnelle une foie le servomécanisme de type MG 996R monté.Cependant, il y a énormément de jeu entre les pièces coulissantes, d'où une grande imprécision dans la commande de l'ensemble. Je comprends mieux l'existence d'un autre modèle de bien meilleure facture. FT
