The DHT11 Temperature and Humidity Sensor Module is a widely used sensor module designed to provide accurate measurements of temperature and humidity.

Here's an overview of the DHT11 sensor module:

Purpose: The DHT11 sensor module is intended for measuring temperature and humidity levels in the surrounding environment.

Accuracy: It provides basic accuracy suitable for many non-critical applications.

Principle: The module combines a capacitive humidity sensor and a thermistor to measure temperature. It outputs digital signals.


Dual Measurement: The DHT11 module offers simultaneous temperature and humidity measurements.

Digital Output: The module communicates with microcontrollers using a single-wire digital signal protocol.

Affordability: The DHT11 sensor module is cost-effective, making it popular for various DIY projects and prototypes.

Ease of Use: Its simple digital interface simplifies integration with microcontrollers.


Indoor Climate Monitoring: Used to measure temperature and humidity levels indoors for maintaining a comfortable environment.

Home Automation: Integrated into HVAC (heating, ventilation, and air conditioning) systems to regulate indoor climate.

Greenhouses: Deployed in greenhouses to ensure optimal conditions for plant growth.

Weather Stations: Deployed in greenhouses to ensure optimal conditions for plant growth.

Using the DHT11:

Wiring: Connect the sensor's data pin to a digital input/output pin on a microcontroller.

Powering the Sensor: The sensor usually operates with a 3.3V or 5V DC power supply.

Reading Values: Utilize provided libraries or functions to read temperature and humidity values from the sensor using the digital signal.


Accuracy: The DHT11 provides basic accuracy suitable for general applications, but it may not meet the demands of highly precise projects.

Calibration: Calibrating the sensor in controlled conditions could improve the accuracy of measurements.

Response Time: The sensor's response time might not be suitable for applications that require rapid temperature or humidity changes.

When integrating the DHT11 Temperature and Humidity Sensor Module into a project, it's important to understand its accuracy limitations and consider its response time, particularly for applications requiring high precision.

Temp & Humidity in a small device

Small little device that provides both Temperature and Humidity.I've tested this next to a Dallas DS18b20 and they are both within 1 degree of each other. Which is off I do not know, but they are "close enough" for me.

Great for my needs

Great for my needs. I hear they are not as good as the upgraded versions dht22, but these are great for basic readings.

ravi kumar

Reliable and easy to use. Just use the dht11 library and set your pins correctly and you'll be good.

Great value, works well!

Works well and easy to use!

prem singh bidla

I received some reasonably accurate sensors.

sugodh kumar
Works as expected

These work great, easy to setup and use. Compared to various other Temp and Humidity devices I own, these are accurate.

tara singh rawat
Easy to program into a sketch etc.

Pretty good accuracy, for general use.

A great product

A Great product

mukul verma
They work as expected.

Only 2 degrees of accuracy.

They work

Not as accurate as the DHT22, but I needed a couple and precision wasn't a must.
