AITRIP 5pcs DHT11 Temperature Humidity Sensor Module Digital 3.3V 5V with Wires for Arduino Raspberry Pi 2 3

DHT11 digital temperature and humidity sensor is a digital signal output with a calibrated temperature and humidity combined sensor.It uses a dedicated digital modules and acquisition of temperature and humidity sensor technology to ensure that products with high reliability and excellent long term stability. Sensor consists of a resistive element and a sense of wet NTC temperature measurement devices, and with a high-performance 8-bit microcontroller connected. The single-wire wiring scheme makes it easy to be integrated to other applications.And the simple communication protocol greatly reduces the programming effort required. Humidity Measure Range 20%-95%,humidity measurement error: +-5%; Temperature Measure Range 0-50°C,temperature measurement error: +-2 degrees. Working voltage: DC 3.3V-5V.Output form: digital output.
