HiLetgo 5pcs DHT11 Digital Temperature & Humidity Sensor Module - 3.3V-5V, 0-50C, 20%-95% RH with Dupont Wires

I recently used this DHT11 Temperature and Humidity Sensor Module in several projects, and I'm thrilled to share my positive experience! As a maker and DIY enthusiast, I've found this module to be an excellent addition to my toolkit.*Why I love it:*1. **Easy to use**: The DHT11 is incredibly simple to integrate into your project, requiring only a single digital input pin on your microcontroller. It is currently being used to monitor the humidity and Attic temperatures.2. **Accurate readings**: This sensor provides reliable and accurate temperature and humidity readings, making it perfect for a wide range of applications.3. **Low power consumption**: With a low power draw, this module won't drain your batteries or add unnecessary complexity to your project.4. **Affordable**: The DHT11 is an incredibly affordable solution for temperature and humidity sensing, making it accessible to makers and hobbyists of all levels.*Real-world applications:* + Home automation projects (e.g., monitoring indoor climate) such as your attic space, garage space, outdoor space etc. + Environmental monitoring (e.g., weather station or air quality tracking) + Maker and DIY projects that require temperature and humidity sensing**In conclusion**, I'm thoroughly impressed with the DHT11 Temperature and Humidity Sensor Module. Its ease of use, accuracy, low power consumption, and affordability make it an excellent choice for anyone looking to add temperature and humidity sensing capabilities to their project.

I'm not at all impressed with how accurate these are, BUT the readings seem very stable over hours, days so I'm happy. I do like the built-in resistor, that saved me some solder work. I use them to monitor temp and humidity in a mealworm farm.Their not-great accuracy combined with their small range makes them just not ideal for anything that needs, well, 1-degree accuracy or range to 150 or 180 degrees, but at this price they are absolutely perfect for general purpose, non-critical applications. Accurately described by the vendor, shipped fast, packaged well, and a good component overall- That's worth 5 stars for me.

I'm using these with esp32 and they are working great. Great value for simple sensors and they are reliable. They are easy to setup in esphome on home assistant.

While there are better sensors, if you don't need extra accuracy these will do the job and still be within 2-3 degrees. From my own usage these were used to act as an "edge" temperature sensor to get a rough estimate of surrounding temperature(s) and they worked fairly well--from a cost point of view, using a better set wouldn't have made much of a difference. One experiment was use a Pi to monitor a PC temps, it helped to understand how much of a thermal gap there is with built-in sensors(SSD/HDD bay/graphics card) and I swapped out a case fan based on that data to improve airflow/temps.

Integrates easily with the DHT11 library for Arduino

Just to clarify another negative review, the sensor actually has 16 bit resolution and reports with 0.1 deg C resolution when used with the Adafruit DHT_Unified_Sensor demo code with an Arduino. While the absolute accuracy may not be great (a degree or two C), the repeatability seems quite good, as others have reported. I'm guessing the reviewer who had a bad experience and only saw 1 deg C resolution was using a library that didn't take advantage of the sensor resolution, or potentially used print statements designed for integers instead of floating point numbers.I haven't tried it with a Raspberry Pi, but with that 1-Wire interface, it should also work quite well, but be aware that the minimum supply voltage is 3.6V, so you would need to power it from the 5V rail and use a level shifter to interface with a 3.3 V logic pin on the Pi.

I use these to track temperature at a second property with and arduino board. ChatGPT helped me get these up and running quickly and they work great.

Some of these don't really work, this one worked and it's really nice. I used it with Arduino and made some cool project
