DHT11 Temperature and Humidity Sensor

<h2>DHT11 Temperature and Humidity Sensor</h2>
<p>Description of DHT11 Temperature and Humidity Sensor –</p>
<p>The DHT11 is a commonly used Digital Temperature and humidity sensor. The sensor comes with a dedicated NTC to measure temperature and an 8-bit microcontroller to output the values of temperature and humidity as serial data. The sensor is also factory-calibrated and hence easy to interface with other microcontrollers.</p>
<p>This Sensor Module is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and outputs a digital signal on the data pin (no analog input pins needed). It's very simple to use, and libraries and sample codes are available for Arduino and Raspberry Pi.</p>
<p>This DHT11 Humidity &amp; Temperature Sensor Module makes is easy to connect to an Arduino or microcontroller as it includes the pull-up resistor required to use the sensor. Only three connections are required to be made to use the sensor – Vcc, Gnd, and Output. We have also included the cables required to connect the DHT11 to a microcontroller.</p>
<h4>Features:</h4>
<ol>
<li>Low-cost Module.</li>
<li>5V power and I/O.</li>
<li>2.5mA max current use during conversion (while requesting data).</li>
<li>Good for 20-80% humidity readings with 5% accuracy.</li>
<li>Good for 0-50°C temperature readings ±2°C accuracy.</li>
<li>No more than 1 Hz sampling rate (once every second).</li>
<li>It comes with cables to make connections to a microcontroller.</li>
</ol>
<p>The sensor can measure temperature from 0°C to 50°C and humidity from 20% to 90% with an accuracy of ±1°C and ±1%. So if you are looking to measure in this range then this sensor might be the right choice for you.</p>
