Overview

Product Overview

The ShillehTek DHT22 Temperature and Humidity Sensor is a popular, easy-to-use module for measuring ambient temperature and relative humidity in Arduino and Raspberry Pi projects. It uses a simple single-wire digital signal, so it is beginner friendly and works great for quick prototypes like room monitors, greenhouse dashboards, home automation triggers, and basic weather station builds. If you want a straightforward sensor for everyday environment readings with tons of example code available, the DHT22 is a solid choice.

Compared to the DHT11, the DHT22 steps up to a -40 to 80 °C range at ±0.5 °C accuracy and 0-100 % relative humidity at ±2-5 %, with a reading every two seconds over the same simple single-wire protocol at 3.3-5 V. The included cable lets you position the sensor away from heat sources for honest readings. The go-to choice when a greenhouse controller or weather station needs data you can trust.

Questions & answers

Frequently asked questions

Does the DHT22 work with Arduino and Raspberry Pi?

Yes. The DHT22 is a digital temperature and humidity sensor commonly used with both Arduino and Raspberry Pi boards, with many existing libraries and wiring examples available for beginner environment-sensing projects.

Is the DHT22 module ready for beginners?

Yes. The ShillehTek module is intended for quick prototyping and comes ready for straightforward wiring, making it suitable for beginners building simple temperature and humidity projects without working from a bare sensor package.

What interface does the DHT22 sensor use?

The DHT22 uses a simple single-wire digital data signal, not an analog output. In a typical setup, the board reads it through a GPIO data connection along with power and ground.

Can the DHT22 build a room or greenhouse monitor?

Yes. The DHT22 is a good fit for room monitors, greenhouse dashboards, home automation triggers, and basic weather station builds where ambient temperature and relative humidity readings are needed.

Why is my DHT22 not returning readings?

Missing or unstable readings are usually caused by incorrect wiring, using the wrong GPIO in code, an incompatible library setup, or polling the sensor too quickly. Verify the example code matches your board and connection.

The temperature sensor does not correctly tell me the right temperature or humidity sensor, please fix this.

electronics project: take the temperature

the DHT component is a common electronics component you can incorporate into your digital electronics projects to obtain the ambient temperature of the environment it operates within.Works great with the raspberry pi and arduino.Easy to (physically) install in the breadboard. Easy enough to interface with in software.

works

we got this to track temps in our freezer to let us know if it ever starts to get warmer aka the freezer goes out. So far it has been accurate and seems to be doing well. It was pretty easy to set up. good investment for peace of mind without costing too much.

Worked for my project

This was easy to use and worked well for my project. It's a good price as well.

I'll keep buying DHT11 for 2.50 instead of these for 11.00. The actual humidity is 36%. The DHT11 calls it 42. The DHT22 calls it 45! Huh? 8.00 more and it it 1% farther off.

Quick and accurate

I'm using this sensor with an arduino for a thermostat project. The readings have been more than accurate enough for my use. I like that the dht22 has a wider reading range over the dht11 sensor. The board is fairly small so it be easy to fit into a 3d printed case

works well

Using in ESP-8266 project. Pretty easy to use. Seems pretty accurate, would use again.

Easy to integrate

This was easy to integrate into one of my projects. No problems with the hardware or finding some code & libraries for it to work. Seems to be fairly reliable and accurate enough for hobby projects.

Easy to use and accurate

I like this sensor compared to others that I ordered because it came with DuPont jumpers which made it super simple to hook up and test before a permanent install. It hooks up super simple to the GPIO header on an RPI, I have not figured out the best way to use it with my ESP32 boards yet but I know it will work. But super easy to hook up and use on a raspberry pi. The hole in the board is nice to be able to make a rigid connection to something. Definitely a nice sensor.

another name for a AM2302

An upgraded version of the DHT11.Better temperature accuracy and wider humidity range than the DHT11.The pinout is electrically identical to the DHT11 for an easy replacement.Your interface will have to be configured for that AM2302 / DHT22 if replacing a DHT11.In my case it was the AM2301 series.
