It 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). 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.\u003cbr\u003e\u003cbr\u003eSimply connect the red 3-5V power, the yellow wire to your data input pin and the black wire 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.\u003c\/p\u003e \u003cp\u003eWe have a Adafruit Learning System guide with schematics, Arduino \u0026amp; CircuitPython code, datasheets and more!\u003cbr\u003e\u003cbr\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\u003cbr\u003e\u003cbr\u003e\u003cb\u003eThere is a 5.1K resistor inside the sensor connecting VCC and DATA so you do not need any additional pullup resistors\u003c\/b\u003e\u003c\/p\u003e\u003ch5\u003eTechnical details\u003c\/h5\u003e\n      \u003cdiv id=\"technical-details\" class=\"panel-collapse collapse in-md in-lg\"\u003e\n        \n\u003cul\u003e\n\u003cli\u003eLow cost\u003c\/li\u003e\n\u003cli\u003e3 to 5V power and I\/O\u003c\/li\u003e\n\u003cli\u003e2.5mA 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\u003e3 wires 23cm long (9\")\u003c\/li\u003e\n\u003cli\u003e27mm wide x 58.75mm tall x 13.30mm deep\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWe have a Adafruit Learning System guide with schematics, Arduino \u0026amp; CircuitPython code, datasheets and more!\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e \u003cul id=\"product-files\"\u003e\n\u003c\/ul\u003e\n\n      \u003c\/div\u003e","brand":"The Pi Hut","offers":[{"title":"Default Title","offer_id":52217284690208,"sku":"eee1787257506093","price":8.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0946\/3231\/3120\/files\/am2302-wired-dht22-temperature-humidity-sensor_1.jpg?v=1787257510","url":"https:\/\/www.elmwoodbasket.shop\/products\/am2302-wired-dht22-temperature-humidity-sensor","provider":"My Store","version":"1.0","type":"link"}
