DHT11 Temperature and Humidity sensor is as powerful as it used to be but easier to use.  This  DHT11 Arduino temperature and humidity sensor has a full range temperature compensation, low power consumption, long term stability and calibrated digital signal. A high-performance 8-bit microcontroller is integrated in the sensor with calibration-coefficient saved in OTP memory to provide accurate temperature readings.

GND: In electronics, we define a point in a circuit to be a kind of zero volts or 0V reference point, on which to base all other voltage measurements. This point is called ground or GND.

DATA: The DHT11 measures the air and outputs a digital signal on this pin.

3.3V  : 'VCC' stands for Voltage Common Collector, we'll connect the VCC pin to 3.3V on the micro:bit

Voltage is the difference in electric potential between two points. As it is difficult to talk about voltage without a reference point, we need another point to compare it to.

 It can be programmed in MakeCode editor and the Arduino IDE. Skip to step 7 to program it with the Arduino IDE.
