The DHT11 is a low cost, simple to use digital temperature and humidity sensor. It's great for hobbyists, makers and data-loggers who want to collect accurate measurements - especially where access to power or wifi is limited. With just four pins it can be easily configured as either I2C or SPI so almost any microcontroller with digital outputs can read data from the sensor. It has a precision of +/-2% for both temperature readings and relative humidity readings which are accurate up to 20 ppm RH. Controlling the DHT11 is also very simple - just set the digital pin to one of 40 different I/O settings. For example, if you want to measure temperature and humidity then just set pin 12 to a logical high value and pin 5 to a logical low value. Simple! There are no additional components needed for the DHT11 - just a battery-backed resistor which can be powered from a single AA battery or 5 volts via a micro-USB connector. The sensor itself is based around a MAX6675 chip from Maxim Integrated so it has all the functionality you would expect from an IRIG1 sensor, including: All the official DHT11 datasheets can also be found here. There are a few software libraries that can be used with the DHT11. These include: The following article is an example of data that was logged by sensors connected to an ESP8266 WiFi module. Detailed instructions on setting up the DHT11 are available here, including doing I2C communication via SPI using Arduino SDK. For those who want to write their own Arduino library for the DHT11, instructions can be found here.
