Hey guys, how are you going recently? You know in China it’s very hot that just like to burn you up. I’ll not go any place without an air conditioner. Unless there is seaside, beach, beauty… So much for this, let’s get back to business. Welcome back to our blog. Today I’ll give you some sweet, the introduction of DHT11 Temperature and R Humidity breakout.

This DHT11 Temperature and Humidity Sensor features a calibrated digital signal output with the temperature and humidity sensor complex. Its technology ensures the high reliability and excellent long-term stability. A high-performance 8-bit microcontroller is connected. This sensor includes a resistive element and a sense of wet NTC temperature measuring devices. It has excellent quality, fast response, anti-interference ability and high cost performance advantages.

Each DHT11 sensors features that extremely accurate calibration of humidity calibration chamber. The calibration coefficients stored in the OTP program memory, internal sensors detect signals in the process, and we should call these calibration coefficients. The single-wire serial interface system is integrated to become quick and easy. Small size, low power, signal transmission distance up to 20 meters, makes it a variety of applications and even the most demanding applications. The product is 4-pin single row pin package. Convenient connection, special packages can be provided according to users need.

Typical application

 

The power supply should be 3-5.5V DC. When power is supplied to sensor, don’t send any instruction to the sensor within one second to pass unstable status. One capacitor valued 100nF can be added between VDD and GND for power filtering. Single-bus data is used for communication between MCU and DHT11.

Ok class is over. If you want to know more about this sensor, just buy it. Acting is the best way to know something.
