DHT11 Humidity and Temperature Sensor With PCB
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.

It is a actually fashionable, extremely low-cost digital temperature and humidity sensor. It makes use of a capacitive humidity sensor, and a thermistor to measure the encompassing air temperature. The result is obtainable by way of a digital sign on the information pin (no analog enter pins wanted). It is pretty easy to make use of however requires cautious timing to seize knowledge. The one actual draw back of this sensor is you will solely get new knowledge from it as soon as each 2 seconds. However, for many functions, this isn’t a difficulty in any respect.
The DHT11 is a generally used temperature and humidity sensor. The sensor comes with a fanatical NTC to dwell temperature and an 8-bit microcontroller to output the values of temperature and humidity as serial knowledge. The sensor is moreover manufacturing unit calibrated and therefore straightforward to interface with different microcontrollers.
The sensor can measure temperature from 0°C to 50°C and humidity from 20% to 90% with an accuracy of ±1°C and ±1%. So should you’re trying to dwell throughout this vary then this sensor may very well be the correct alternative for you. This module must be related as follows: The leftmost pin (marked ‘S’ on PCB) to your knowledge enter and The centre pin to three.0 to five.5V energy.
The rightmost pin (marked ‘-‘ on PCB) to floor. Though it makes use of a single-wire to ship knowledge it is not Dallas One Wire suitable! If you need a number of sensors, all will need to have its personal knowledge pin! The DHT11 Sensor is manufacturing unit calibrated and outputs serial knowledge.The DHT11 sensor can both be bought as a sensor or as a module. Both method, the efficiency of the sensor is similar
The DHT11 is a low-cost model of the DHT22 sensor. The dearer DHT22 is extra exact, extra correct and works throughout a wider temperature and humidity vary
Its functions are:
Measure temperature and humidity, Native Climate station, Computerized local weather management, Setting monitoring.
