DHT11 Humidity and Temperature Digital Sensor

Code: MR003-005.2
This board is a breakout board for the DHT11 sensor and gives a digital output that is proportional to temperature and humidity measured.

Description

This board is a breakout board for the DHT11 sensor and gives a digital output that is proportional to temperature and humidity measured by the sensor. Technology used to produce the DHT11 sensor grants high reliability, excellent long-term stability and very fast response time.

Each DHT11 element is accurately calibrated in the laboratory. Calibration coefficient is stored in the internal OTP memory and this value is used by the sensor’s internal signal detecting process. The single-wire serial interface makes the integration of this sensor in digital system quick and easy.

Sensor physical interfacing is realized through a 3-pin connector: +5V, GND and DATA. First two pins are power supply and ground and they are used to power the sensor, the third one is the sensor digital output signal.

Its small physical size (1.05”x0.7”) and its very light weight (just 0.1oz) make this board an ideal choice to implementing small robots and ambient monitoring systems.
