Digital-output relative humidity & temperature sensor/module DHT11 Resisitive-type humidity and temperature module/sensor 1. Feature & Application: * Full range temperature compensated * Relative humidity and temperature measurement * Calibrated digital signal *Outstanding long-term stability *Extra components not needed * Long transmission distance * Low power consumption *4 pins packaged and fully interchangeable 2. Description: DHT11 output calibrated digital signal. It utilizes exclusive digital-signal-collecting-technique and humidity sensing technology, assuring its reliability and stability. Its sensing elements is connected with 8-bit single-chip computer. Every sensor of this model is temperature compensated and calibrated in accurate calibration chamber and the calibration-coefficient is saved in OTP memory. Small size & low consumption & long transmission distance(20m) enable DHT11 to be suited in all kinds of harsh application occasions. Single-row packaged with four pins, making the connection very convenient. 13.
