Descripción
Medición de humedad relativa y temperatura
Salida digital calibrada
Excelente estabilidad a largo plazo
Completamente intercambiable
El Sensor de Temperatura y Humedad Gravity DHT11 presenta una salida de señal digital calibrada con el complejo sensor de temperatura y humedad. Su tecnología garantiza la alta fiabilidad y excelente estabilidad a largo plazo. Se debe conectar un microcontrolador de alto rendimiento de 8 bits para aprovechar al máximo el sensor. Este sensor incluye un elemento resistivo y un conjunto de dispositivos de medición de temperatura húmeda NTC. Tiene excelente calidad, respuesta rápida, capacidad anti-interferente y ventajas de rendimiento de alto costo.
Cada sensor DHT11 presenta una calibración extremadamente precisa de la cámara de calibración de humedad. Los coeficientes de calibración almacenados en la memoria del programa OTP, los sensores internos detectan señales en el proceso, deberíamos llamar a estos coeficientes de calibración. El sistema de interfaz serial de un solo cable está integrado para ser rápido y fácil. Tamaño pequeño, baja potencia, distancia de transmisión de señal de hasta 20 metros, por lo que es util en una variedad de aplicaciones e incluso las aplicaciones más exigentes. El producto es un paquete una sola fila de 4 pines. Conexión conveniente, paquetes especiales pueden ser proporcionados de acuerdo a las necesidades del usuario.
Have a newer version where they cut corners. The board was shortened and the sensor now hangs freely off the end. Disappointing for a DFRobot product. I removed the DH11 and replaced it on the backside for better support. The leads are reversed but I just rewired the connector. Works well.
