DHT11 digital temperature and humidity sensor is a temperature and humidity composite sensor with calibrated
digital signal output. It uses dedicated digital module acquisition technology and temperature and humidity sensing
technology to ensure that the product has extremely high reliability and excellent long-term stability.
The sensor includes a resistive humidity sensing element and an NTC temperature measuring element,
and is connected with a high-performance 8-bit single-chip microcomputer. Therefore, the product has
the advantages of excellent quality, ultra-fast response, strong anti-interference ability, and high cost
performance.
The single-wire serial interface makes system integration easy and quick. Ultra-small size, extremely
low power consumption, and signal transmission distance of up to 20 meters or more, making it the
best choice for various applications and even the most demanding applications. The product is easy
to connect and can be directly plugged into the Arduino sensor expansion board.
