Today, this video discusses how to use DHT 11 Sensor module with Arduino
The DHT11 is a basic, ultra-low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed). It's fairly simple to use but requires careful timing to grab data.
The DHT11 calculates relative humidity by measuring the electrical resistance between two electrodes. The humidity sensing component of the DHT11 is a moisture-holding substrate with the electrodes applied to the surface. ... The change in resistance between the two electrodes is proportional to the relative humidity.
