FRANCISCO LOZADA / Mbed 2 deprecated DHT11_Temp_Humidity

UPS MAESTRIA

Dependencies:   mbed DHT

El sensor DHT11 es un sensor conexión es trivial, pero cabe destacar que se vende en dos encapsulados, uno de tres pines que son GND, Data y Vcc, y otro 4 pines y uno de ellos, sencillamente sobra y no se conecta. Normalmente viene rotulado en el sensor el nombre de cada pin.
