Weewooday 10 Pieces DHT11 Temperature Humidity Sensor Module Digital Single Bus 3.3V-5V, Humidity Measure Range 20%-95% Temperature Measure Range 0-50? with Wires Compatible with Arduino/Raspberry Pi

I have nothing against the DHT11, it does what you pay for and what it was designed for. But, the DHT22 is a better bang for the buck.The large temp range sold me on the DHT22 because I needed to monitor a freezer that went below -10F.DHT11-4F to 140F plus/minus 2%Hum 5% to 95% plus/minus 5%DHT22-40F to 176F plus/minus 0.5%Hum 0% to 100% plus/minus 2%

I have been using DHT11s for some time with ESP8266s and 32s. I run Tasmota on them. This batch I bought, not one read the temp correctly. Reports 1 Celsius and -20% Humidity. I used some other DHT11s I had from another vender/purchase and they work as expected. Went through all 20 of them, not one worked.

I use these in as many projects as I can. They are cheaper than the dht22 but are a bit less accurate. They work well enough for what I'm doing though. I have a few logging data to a grafana instance to average the temperature and humidity in my yard and am using it for a distributed weather station.

I also got 10 of them and they don't work as a DHT11. Work ok as DHT22.Maybe, I am questioning the accuracy.

These are good if you need temp but not super accurate temperature. Make sure you keep them at a distance from the main board(ie esp) as they will pick up the heat they generate.

These are not dht11 I tried using them with a pico W with thonny and it would say 0°C and 1% humidity, changed the code for a DHT22 and it worked

I'm bought these to see if they were going to be accurate and consists. These have been both accurate and consistent. I will be putting these in my greenhouse so I can keep tabs on the temp and humidity from inside my house. I know you can buy something off the shelf, but what fun is that!

I've been using DHT11 sensors for over 4 years now. I only have 1 left of my old batch and it truly is the only one in the entire house that works. NONE OF THESE SENSORS FUNCTIONED PROPERLY AT ALL. Garbage quality. SHAME.The markings on the device and the ones in the picture don't even match up. This company is so bad it's laughable.
