    Buen producto de buena calidad y buen acabado. Funciona correctamente. El plazo de entrega excelente. Muy bien embalado para su transporte. Volveré a comprar sin dudarlo. Recomiendo este vendedor a todo el mundo.

  6. Customer

    Funciona y es tal como aparece en la descripción, pero el consumo del ESP01 le incrementa 2,5 grados al DHT22, desde que lo enciendes hasta 5 minutos va subiendo. Habrá que programar para disminuir el consumo a ver qué pasa.
