Std edition Présence secteur 4 entrées / Live 230 V input board opto-isolated

Description
4 230 V inputs to monitor togle relais. Let you know if light is on or off and togle them witha domestic automationsystem. Tested on Arduino and ESP32 board. May install a cap to filter 50/100 Hz or do it by soft (20 mS timer for on/of) A 1-wire variant will be comming soon.
4 entrées 230 V isolées par optocoupleur pour permettre de voir l'état d'un télérupteur (lumière allumée ou éteinte) puis de piloter celui-ci avec un système domotique. Testé sur Arduino et module ESP 32. On peux utiliser un condensateur pour filtrer le 50/100 Hz ou via le programme avec une tempo de 20 mS (choix personnel). Une version 1-wire est dans les tuyaux.
