## Description

Perfect for your next weather station! This module includes all passives that you need to run the sensor directly on the module and only uses one pin to return the temperature and humidity!

This classic maker sensor is extremely well documented with many libraries for almost any microcontroller or single-board computer.

### Specifications

- Voltage Input: 3.3-5V
- Temperature Range: -40~80°C, with ±0.5°C error
- Humidity Range: 0-100% RH with ±2% RH error

### Examples

#### Raspberry Pi Pico - Micropython

```
import dht<br></br>import time<br></br>from machine import Pin

# Define pin for DHT22 sensor
DHT_PIN = 2

# Initialize DHT22 sensor object
dht22 = dht.DHT22(Pin(DHT_PIN))

# Loop to read temperature and humidity every second
while True:
    try:
        dht22.measure()
        temperature = dht22.temperature()
        humidity = dht22.humidity()
        print("Temperature: {:.1f} C".format(temperature))
        print("Humidity: {:.1f} %".format(humidity))
    except OSError as e:
        print("Failed to read DHT22 sensor:", e)

    time.sleep(1)
```
