Снятие показаний с погодного датчика Oregon THN132N
(Погодная станция Oregon Scientific Bar339P)
Краткое описание работы
- Считываем показание с датчика
- Формируем строку для передачи на сервер вида: deviceid=EA4C108122234030&channel=1&temperature=22&battery=90, где:
- deviceid - ID температурного датчика
- channel - Канал, на котором настроен датчик. Выбирается при помощи тумблера на устройстве.
- temperature - Темпаратура
- battery - Текущий заряд батареи
- Отправляем данные в БД сайта
