Reading temperature and humidity with the DHT22 sensor and the Raspberry Pi Pico

Unlike the Arduino Nano, the Raspberry Pi Pico requires an external sensor and an additional software library to measure the temperature and humidity.

In this recipe, we will show how to use the DHT22 sensor with a Raspberry Pico to get temperature and humidity measurements.

Getting ready

The temperature and humidity sensor module considered for the Raspberry Pi Pico is the low-cost AM2302.

As shown in the following diagram, the AM2302 module is a through-hole component with three pins that integrates the DHT22 temperature and humidity sensor:

Figure 3.18 summarizes the key characteristics of the DHT22 sensor:

DHT11 is another popular temperature and humidity sensor from the DHT family. However, we cannot...
