У этой аппаратуры всего 2 недостатка и оба они дешево устраняются при наличии рук, растущих из плеч.
1. Работа от батареек. Решается покупкой платы модуля для powerbank 18650 за $0.5 и аккумулятора от сотового телефона за $2. полчаса с паяльником. Плата отвечает за зарядку аккумулятора, а также выдает стабильные 5В. Контроль заряда аккумулятора делается перерезанием дорожки на плате аппаратуры и подпайкой провода от аккумулятора или выпаять резистор и подключить через внешний, как у меня на фото. При этом аппаратура отображает напряжение аккумулятора в вольтах и сигнализирует звуком при любом настроенном уровне разряда.
2. Дальность не более 300м. Решается установкой радиомодуля LORA 433Mhz - дальность до 40 км!!! Позже залью видео по переделке на youtube.
