Как использовать операторы if между двумя действиями с намерением? У меня есть два разных вида деятельности по сбору данных с внешних датчиков. Я хотел бы управлять некоторыми выводами GPIO Activity1 на основе значений датчиков Activity2 .

Мероприятие 1

В приведенных выше кодах контакты GPIO должны управляться значениями датчика co2ppm 1 (если значение датчика co2ppm 1 превышает 2000, он должен включить вывод GPIO 9).
