Introduction This DHT11 Temperature and Humidity Sensor features calibrated digital signal output with the temperature and humidity sensor complex. Its technology ensures the high reliability and excellent long-term stability. A high-performance 8-bit microcontroller is connected. This sensor includes a resistive element and a sense of wet NTC temperature measuring devices. It has excellent quality, fast response and anti-interference ability. Each DHT11 sensor features extremely accurate calibration of humidity calibration chamber. The calibration coefficients stored in the OTP program memory, internal sensors detect signals in the process. The single-wire serial interface system is integrated to become quick and easy. Small size, low power, signal transmission distance up to 20 meters, making it must for a variety of applications and even the most demanding applications. Specification 1. Supply Voltage: +5 V 2. Temperature range :0-50 °C error of ± 2 °C 3. Humidity :20-90% RH ± 5% RH error 4. Interface: Digital
