It connects directly to a microcontroller and outputs both measured values via a simple single-wire protocol that requires only one signal line. This eliminates the need for complex analog measuring circuits and analog-to-digital converters.\u003c\/p\u003e \u003cp\u003eThe sensor measures temperatures from 0 to 50 °C and relative humidity between 20 and 80%. Accuracy is ±2 °C for temperature and ±5% for humidity, which is sufficient for many practical applications. Calibration is not required because measured-value processing is already integrated.\u003c\/p\u003e \u003cp\u003eTypical applications include indoor climate monitoring in homes or workshops, automatic irrigation with humidity measurement, data loggers for storage or cultivation conditions, and weather stations. Projects with simple control systems, such as automatic ventilation or heating, can also be implemented.\u003c\/p\u003e \u003cp\u003eOperation requires a supply voltage between 3.3 and 5.5 V. The sensor can be connected to all common microcontroller boards; an interface module is not required. A power supply and the corresponding control software must be provided.\u003c\/p\u003e \u003ch3\u003eSafety information\u003c\/h3\u003e \u003cp\u003eThis sensor is intended exclusively for building prototypes and for testing and development purposes. The operating voltage must not exceed the specified limits to prevent damage. If you have questions about integrating it into an existing system, consult a qualified electrician before commissioning.\u003c\/p\u003e \u003ch4\u003eScope of delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x DHT11 temperature and humidity sensor\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":65998322106717,"sku":"F23106606","price":3.22,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/dht11-temperatur-und-luftfeuchtigkeitssensor-funduino-9686590.png?v=1791496459","url":"https:\/\/funduino.com\/en\/products\/dht11-temperature-and-humidity-sensor","provider":"Funduino","version":"1.0","type":"link"}
