The DHT22 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).

Simply connect the first pin on the left to 3-5V power, the second pin to your data input pin and the right most 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.

Compared to the DHT11, this sensor is more precise, more accurate and works in a bigger range of temperature/humidity, but its larger and more expensive.

Comes with a 4.7K - 10K resistor, which you will want to use as a pullup from the data pin to VCC.

DHT11 is an inexpensive sensor that provides calibrated digital outputs for ambient temperature and relative humidity. It comes in a single row 4-pin package and operates from 3 to 5.5V power supply. It can measure temperature from 0-50 °C with an accuracy of ±2°C and relative humidity ranging from 20-95% with an accuracy of ±5%. It has got its own proprietary 1-wire protocol, and therefore, the communication between the sensor and a microcontroller is not possible through a direct interface with any of its peripherals. The protocol must be implemented in the firmware of the MCU through bit-banging of an I/O pin.

Low-cost temperature and humidity sensor. Requires a single digital I/O pin to read both temperature and humidity values.

Minimum Order Quantity1 Piece
Size28mm x 12mm x 8mm

Measuring current1-2.5mA
Standby current100-150 micro A
Humidityfrom 20-80% humidity readings with 5% accuracy
temperature0-50 DegreeC temperature readings +-2 Degree C accuracy

This is a very popular, ultra low cost digital temperature and humidity sensor. It uses a capacitive humidity sensor, and a thermistor to measure the surrounding air temperature. The result is available via a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds. But, for most applications this is not an issue at all.


This module should be connected as follows:

  • The left most pin (marked 'S' on PCB) to your data input
  • The center pin to 3.0 to 5.5V power
  • The right most pin (marked '-' on PCB) 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!


The DHT11 is a low cost version of the DHT22 sensor. The more expensive DHT22 is more precise, more accurate and works in a wider temperature and humidity range.
