Temperature and Humidity Sensor Module - DHT11

This module consist of a pre-calibrated DHT11 digital humidity and temperature sensor and a 1 kΩ resistor. The DHT11 uses an internal thermistor and a capacitive humidity sensor to determine environment conditions and outputs a serial digital signal. The module has a resistive sense technology coupled with NTC thermistor, for the precise reading of the relative Humidity and surrounding temperature. A high-performance 8-Bit microcontroller inside the module is responsible to convert in the form of a digital signal on a single data pin. The sensing update frequency is to be measured at every 2sec (0.5Hz).
This complete low-cost arrangement makes the device an ideal sensing setup to be hooked up directly to any kind of microcontroller boards like Arduino and raspberry pi.
