Module interface specification (3-wire)
1 VCC 3.3V-5V external
2 GND GND External
3 DO small plate switch digital output interface connected to the microcontroller IO port
Operating specification
- Power's voltage should be 3-5.5V DC. When power is supplied to sensor, don't send any instruction to the sensor within one second to pass unstable status. One capacitor valued 100nF can be added between VDD and GND for power filtering.
- Communication and signal Single-bus data is used for communication between MCU and DHT11.
Applications:
- Measure temperature and humidity
- Local Weather station
- Automatic climate control
- Environment monitoring

DHT11 Temperature and humidity sensor Module supplied with the breakout board and the cable, is the right choice for you if you need precise and reliable measurements of temperature and humidity levels for your Arduino or Raspberry Pi based projects. it's ideal for many applications such as monitoring room temperature or as a weather station.
Since the sensor can be operated with both 3.3V and 5V voltages, it is suitable for connection to all standard boards such as Arduino, RN-Control, Raspberry Pi and all other microcontrollers.
In addition to the operating voltage connection, only one microcontroller port needs to be connected to the sensor.
