It combines an NTC thermistor for temperature measurement with a capacitive humidity sensor, and sends digital readings to microcontrollers such as Arduino.<\/p>\n<h4>Specifications<\/h4>\n<ul>\n<li><strong>Temperature range:<\/strong> 0\u201350 \u00b0C<\/li>\n<li><strong>Temperature accuracy:<\/strong> \u00b12 \u00b0C<\/li>\n<li><strong>Humidity range:<\/strong> 20\u201390% RH<\/li>\n<li><strong>Humidity accuracy:<\/strong> \u00b15% RH<\/li>\n<li><strong>Operating voltage:<\/strong> 3.5\u20135.5 V<\/li>\n<li><strong>Current:<\/strong> 0.3 mA while measuring; 60 \u00b5A in standby<\/li>\n<li><strong>Data output:<\/strong> digital single-wire protocol<\/li>\n<li><strong>Sampling rate:<\/strong> 1 Hz (one reading per second)<\/li>\n<\/ul>\n<h4>How it works<\/h4>\n<p>An onboard microcontroller converts the sensor readings into a digital signal that can be read by a compatible microcontroller.<\/p>\n<h4>Applications<\/h4>\n<ul>\n<li>Local weather stations<\/li>\n<li>Automatic climate-control systems<\/li>\n<li>Environmental monitoring<\/li>\n<li>Educational and hobby projects<\/li>\n<\/ul>\n<h4>Pinout<\/h4>\n<p>The DHT11 is available as a bare 4-pin sensor or as a module; pin arrangements can differ between versions.<\/p>\n<ul>\n<li><strong>Bare 4-pin sensor:<\/strong> VCC (3.5\u20135.5 V), Data, NC (not connected), GND<\/li>\n<li><strong>Module:<\/strong> VCC, Data, GND<\/li>\n<\/ul>\n<h4>Using it with Arduino Uno<\/h4>\n<h5>Basic
