About this item

  • DHT11 Sensor consists of a resistive element and a sense of wet NTC temperature measurement devices, is a digital signal output with a calibrated temperature and humidity combined sensor and with a high-performance 8-bit microcontroller connected
  • It uses a dedicated digital modules and acquisition of temperature and humidity sensor technology to ensure that products with high reliability and excellent long term stability
  • The single-wire wiring scheme makes it easy to be integrated to other applications.And the simple communication protocol greatly reduces the programming effort required
  • Humidity Measure Range 20%-95%,humidity measurement error: ±5%; Temperature Measure Range 0-50°C,temperature measurement error: ±2 degrees
  • Working voltage: DC 3.3V-5V.Output form: digital output

The ones I received only read 0. I tried both. I bought new ones and used the exact same software and they worked perfectly and immediately. Do not bother with this company.

I needed a sensor ASAP for a school project after my original sensor stopped working. I have been trying to get the two sensors to work, however all I've been getting is 1C on the Arduino serial port and just that. This is frustrating considering these might be my only hope.

All I did was follow the Arduino sample and it worked perfect. Very easy to use.

These sensors were total junk. Put it in the freezer- 32F. Put it in the oven- 32F. I thought maybe they were just calibrated incorrectly, but the temp only changes slightly. This is the result of a LOT of testing and was never accurate. Do not trust the maker of this product.

Better than DHT11.

This was perfect for a Raspberry Pi weather project. The sensors came with the necessary jumper wires to connect to my pi. They seem to be accurate enough and work flawlessly with the pi. Great value here for the money for your next project.

I'm prototyping new project and found these sensors to be accurate and a great value. I will be ordering many more of these!
