Product Material: Plastic Size: 17 * 4.5 * 6.5cm Model: Temperature and Humidity-DHT11 Humidity range: 5% -95% RH Humidity measuring range: 95 (RH) Working temperature: 50 () Supply voltage: 5.5 (V) Power supply current: 20 (mA) Quantity: 5 pieces Package content: 5 * temperature and humidity sensor 1. Since the sensor can be operated with both 3.3V and 5V it is suitable for connection to all common boards such as RN-Control, Raspberry Pi and all other microcontrollers. 2. In addition to the operating voltage, only one port needs to be connected to the sensor 3. The output takes place serially as a digital bit sequence: This makes the sensor ideal for monitoring the room climate or setting up a weather station. 4. The DHT11 sensor is a combined temperature and humidity sensor with a calibrated digital signal output It is a reliable sensor for determining temperature and humidity. 5. The product has excellent quality quick response, anti-interference ability, low cost and other advantages.
