DHT22 Digital Temperature and Humidity Sensor in Pakistan

@ MODERN HALLROAD

DHT22 Digital Temperature and Humidity Sensor is a basic, 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.

DHT22 Digital Temperature and Humidity Sensor is a basic, 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.

These sensors are very popular for electronics hobbyists because there are very cheap but still providing great performance.

DHT22 Digital Temperature and Humidity Sensor is a commonly used Temperature and humidity sensor. The sensor comes with a dedicated NTC to measure temperature and an 8-bit microcontroller to output the values of temperature and humidity as serial data. The sensor is also factory calibrated and hence easy to interface with other microcontrollers.

DHT22 Digital Temperature and Humidity Sensor can measure temperature from -40°C to 80°C and humidity from 0% to 100% with an accuracy of ±1°C and ±1%. So if you are looking to measure in this range then this sensor might be the right choice for you. The DHT22 Sensor is factory calibrated and outputs serial data and hence it is highly easy to set it up.

Simply connect the first pin on the left to 3-5V power, the second pin to your data input pin, and the rightmost pin to ground. Although it uses a single wire to send data it is not Dallas One Wire compatible! If you want multiple sensors, each one must have its own data pin.

DHT22 Digital Temperature and Humidity Sensor is capable of reading humidity over the full range of 0 to 99.9% with an accuracy of +/- 2% and temperature over the range of -40 to 125°C with an accuracy of +/- 0.5°C. The humidity accuracy increases to +/-5% at temperature extremes.
