DHT22 Digital Temperature & Humidity Sensor Module for Arduino DIY Projects Black module

<p>If you are wandering to build a device that detects temperature and humidity from the atmosphere, then This sensor is needed for you. </p> <p>The DHT22 Digital Temperature and Humidity Sensor Module AM2302 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 spits out a digital signal on the data pin (no analog input pins needed).</p> <p><strong>It’s fairly simple to use but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old.</strong></p> <h4><strong>Features :</strong></h4> <ol> <li>High precision</li> <li>Capacitive type</li> <li>Full range temperature compensated</li> <li>Relative humidity and temperature measurement</li> <li>Calibrated digital signal</li> <li>Outstanding long-term stability</li> <li>Extra components not needed</li> <li>Long transmission distance</li> <li>Low power consumption</li> <li>4 pins packaged and fully interchangeable</li> </ol> <hr /> <h4><strong>Package Includes :</strong></h4> <p>1 x DHT22 Digital Temperature and Humidity Sensor Module AM2302</p>
