High-accuracy DHT22 / AM2302 digital temperature and humidity sensor module for Arduino, ESP32, Raspberry Pi, ESPHome, and Home Assistant projects. Offers significantly better accuracy and wider operating range than the popular DHT11 sensor.

Temperature & humidity sensing
Digital single-bus output
Built-in pull-up resistor
3.3V & 5V compatible
Ideal for smart home projects

Quick Start

Connect power

Wire VCC to 3.3V or 5V and connect GND.

Connect DATA pin

Use any digital GPIO pin on Arduino or ESP32.

Install library

Use the standard DHT sensor library or native ESPHome support.

Read live data

Begin monitoring temperature and humidity instantly.

Please note: This module includes the onboard pull-up resistor already fitted for plug-and-play operation.

How It Works

Internal sensor measures environment

The DHT22 continuously monitors surrounding temperature and humidity.

Digital conversion

Sensor data is processed internally and transmitted digitally.

Single-wire communication

Only one DATA pin is required for communication.

Microcontroller reads values

Arduino, ESP32, or Raspberry Pi receives live readings for automation or display.

Please note: Recommended minimum interval between readings is 2 seconds.

Common Questions

What is the difference between DHT11 and DHT22?

DHT22 offers significantly better accuracy, wider temperature range, and improved humidity sensing compared to DHT11.

Does this module include the pull-up resistor?

Yes. The pull-up resistor is already installed onboard, so no external resistor is required.

Will it work with ESPHome and Home Assistant?

Yes. DHT22 sensors are natively supported by ESPHome and integrate easily into Home Assistant dashboards.

Please note: Compatible with Arduino IDE, MicroPython, CircuitPython, and ESPHome environments.

Why buy from NZN

International prices. None of the international wait.

We're a small Kiwi-owned shop, and we stock the same boards and parts you'd usually order from overseas, for about the same price. The only real difference is they ship from Te Awamutu, so you get them in a few days instead of waiting weeks.

Run by Kiwis, here in Te Awamutu

We're NZ owned and operated, and every order is picked, packed and sent from our place in Te Awamutu, Waikato.

Get it in days, not weeks

Order before 8am and it ships the same day, otherwise within 24 hours guaranteed. No waiting three to six weeks for a parcel to crawl over from overseas.

Low prices are the goal

As a maker myself, I want New Zealand to have a genuine low-price local option for electronics, not overpriced shelves or a long wait on an international parcel.
