The DHT11 sensor is low-cost Temperature and Humidity sensor that is ideal for hobbyists and prototyping applications. The DHT11 temperature sensor range: 0 – 50°C (±2°C) and DHT11 humidity sensor range: 20-80% (±5%). Its Supply voltage: 3 to 5.5V. DHT11 sensor uses a OneWire protocol. It integrates a thermistor and a capacitive humidity sensor. An integrated ADC converter converts the measured values into a digital signal, which is then output via the OneWire interface.
The photoresistor or LDR (Light Dependent Resistor) is a light-sensitive semiconductor element that changes its resistance value according to the intensity of the light: the higher the light intensity on the sensitive surface of the LDR, the smaller its resistance value becomes.
The 5V Arduino Boards reads and processes analog signals in a voltage range from 0 to 5 volts. The microcontroller of the Arduino board has an internal Analog-to-digital converter (ADC) for processing the analog input signals. The Arduino Uno, for instance, has six analog channels, in which six analog voltages (i.e. sensors) can be processed in parallel. The ports available for this purpose are labeled A0 to A5 on the Arduino Uno
Arduino digital pins know only two states: HIGH voltage (1’s) and LOW voltage (0’s), where 1 corresponds to a voltage of 5 volts and 0 to a voltage of 0 volts. The signals to be read in at the digital inputs come from other digital circuits such as push-button or limit switch, or sensors with digital outputs.
