Sensor Details
What is the DHT Sensor?
The DHT family of sensors (like DHT11 and DHT22) are popular, low-cost digital sensors that measure ambient temperature and relative humidity. They are easy to interface with microcontrollers.
What it Measures:
- Ambient Temperature (in °C or °F)
- Relative Humidity (in %)
How does it work?
A DHT sensor contains two components: a thermistor for measuring temperature and a capacitive humidity sensor. An internal chip processes the analog readings from these components and outputs a single digital signal containing both temperature and humidity data, which can be easily read by a microcontroller.
Common Applications:
- Weather stations.
- HVAC (Heating, Ventilation, and Air Conditioning) systems.
- Home automation and smart thermostats.
- Agriculture and greenhouse monitoring.
- Data logging for environmental conditions.
