2pcs DHT11 Temperature Humidity Sensor Module Digital Temperature Humidity Sensor 3.3V-5V with Wires for Arduino Raspberry Pi 2 3 (2pcs DHT11)

Both of these sensors have worked well for me. I'm using them with an Arduino Every and a Moteino USB. The Arduino dht11 library works well with these. I use the low power library with the Moteino, power them "on" with one of the digital pins, but only for a second or two to take the reading to save power. They give me a reading that is within one degree of a commercial thermometer that I have.

project worthy

This does was it says, it records temperature and humidity. The sensor is quick for humidity, but takes a little while to show temperature, lagging by a few seconds and an occasional checksum error, neither of which are a show stopper for my uses. I am using a Raspberry PI Zero W for reading values and it works well with this sensor in either Python or C.

I used this DTH11 with an ESP-01 WiFi chip running Tasmota software and it was recognize immediately. Tasmota figures the dewpoint and displays that too. The temperature was off by almost 2 degrees but Tasmota allows correction easily with a console command..

Exactly what I needed for a project. They look decent, and shipped with the external wires for hookup as well! (and fit my breadboard;-)

I have been running an Arduino-based system for monitoring and controlling the grow lights and heat in my winter greenhouse for over 10 years. Usually I'll have to replace the DHT11 module every 4-5 years since it's one item that's exposed (not in a sealed box).I got this as a replacement, and thought to get two so I'll have a spare. The first one failed after 3 days - it first began returning the same temperature and humidity values every time, then after restarting the system return only 0 (this is a common failure mode for the DHT11).I then swapped in the second and it's already exhibiting intermittent failures. Although these came in a sealed anti-static bag, they show signs of sloppy soldering (see the burn marks in the picture). I suspect these are parts that were binned as defective, and somewhere down the line we are getting sold this crap. Do not buy these. I'd rather have things that are defective on arrival than things that give me a false sense of reassurance then fail after a few days in service. I will buy replacements from somewhere else.

I ordered two of the temperature sensors and they both work with my Arduino. I haven't compared them directly and don't know how accurate they are, but they work.

They work in so far as they give a readout when properly configured and programmed. But both for me were reporting temperatures 10 degrees higher than actual.
