Humidity & Temperature Basic Sensor Module DHT11: 马来西亚的首选 Jit Sen Electronics Sdn Bhd

详情

This is a digital temperature and humidity sensor module that works with all of the Arduino micro-controllers. Because it is a digital sensor it only necessitates 3 connections, Vcc, GND, and a digital pin for data output. With this sensor, you get two measurements (humidity and temp) while only using one digital pin on the Arduino! This sensor would be perfect for creating an HVAC control system or for controlling something like a food dehydrator.

This humidity and temperature sensor is very popular and has an Arduino Library dedicated to it.

Features:

Sensor is composed of a resistive humidity sensing component and an NTC temperature testing component and connects with 8-byte MCU
MCU outputs a digital code
Fast response and great anti-interference capability
Durable and long lasting sensor
Low power consumption
Based on the DHT11 sensor architecture
