Arduino Mega 2560
DHT sensors can measure temperature and humidity. You can receive fresh measurements every 2 seconds in the form of digital signals. DHT11 can sense temperature from 0 to 50 °C and humidity from 20 to 80% RH. DHT22 can sense temperature from -40 to 80 °C and humidity from 0 to 100% RH. The DHT Controller Device manages communication between a DHT sensor and the current Ozeki software.
Required hardware
- Arduino Mega 2560
- DHT11 sensor
- Resistor 4.7kΩ
