DHT22/AM2302 Temperature and Humidity Sensor Accuracy

[toc] Earlier this week I wrote an article about how to use the DHT22/AM2302 temperature and humidity sensor with interrupts on an Arduino.; you can see that article here. After spending more time with the DHT22/AM2302 sensor, I’ve learned the humidity part of the sensor is not accurate at all. The temperature part of the […]

Arduino: Read DHT22/AM2302 Temperature and Humidity Sensor Using Interrupts

[toc] There are many sites where you can find Arduino schematics and code to read a temperature and humidity sensor then display that data on the Serial Monitor. I have not worked with the (more accurate) DHT22/AM2302 sensors and wanted to test them. In addition, I will be demonstrating how to use interrupts (instead of […]
