It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and outputs a digital signal on the data pin. Its 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.\u003c\/p\u003e\n\u003cp\u003eSimply connect the first pin on the left to 3-5V power, the second pin to your data input pin and the right most pin to ground. Although it uses a single-wire to send data it is not Dallas One Wire compatible! If you want multiple sensors, each one must have its own data pin! We have written an Arduino library with example code\u003c\/p\u003e\n\u003cp\u003eCompared to the DHT11, this sensor is more precise, more accurate and works in a bigger range of temperature\/humidity, but its larger and more expensive\u003c\/p\u003e\n\u003cp\u003eComes with a 4.7K – 10K resistor, which you will want to use as a pullup from the data pin to VCC.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTECHNICAL DETAILS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e3 to 5V power and I\/O\u003c\/li\u003e\n\u003cli\u003e5mA max current use during conversion (while requesting data)\u003c\/li\u003e\n\u003cli\u003eGood for 0-100% humidity readings with 2-5% accuracy\u003c\/li\u003e\n\u003cli\u003eGood for -40 to 80°C temperature readings ±0.5°C accuracy\u003c\/li\u003e\n\u003cli\u003eNo more than 0.5 Hz sampling rate (once every 2 seconds)\u003c\/li\u003e\n\u003cli\u003eBody size 27mm x 59mm x 13.5mm (1.05? x 2.32? x 0.53?)\u003c\/li\u003e\n\u003cli\u003e4 pins, 0.1? spacing\u003c\/li\u003e\n\u003cli\u003eWeight (just the DHT22): 2.4g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDownloads:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn-shop.adafruit.com\/datasheets\/DHT22.pdf\"\u003eDHT22 datasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/dht\"\u003eArduino library and example code\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/dht\"\u003eDetailed usage tutorial\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Others","offers":[{"title":"Default Title","offer_id":42292823621823,"sku":"MLE00559","price":200.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/e7ce7a3a446ebc0b9ff710832feb0f12.jpg?v=1735815265","url":"https:\/\/makerlab.ph\/products\/dht22-temperature-humidity-sensor-module","provider":"Makerlab PH","version":"1.0","type":"link"}
