SPECIFICATION
- Humidity measuring range: 20%~90%RH(0~50 degree (Temperature compensation).
- Temperature measuring range: 0~+50 degree.
- Humidity measurement accuracy: ±5.0%RH.
- Temperature measurement accuracy: ±2.0degree.
- Low power consumption.
- Relative humidity and temperature measurement
- All calibration, digital output
- Excellent long-term stability
- The DHT-11 Digital Temperature And Humidity Sensor is a basic, ultra-low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed).
- It's fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so in your code please use sensor reading interval at 2 seconds or more. Compared to the DHT22, this sensor is less precise, less accurate and works in a smaller range of temperature/humidity.
- But despite its disadvantages over DHT22, it is a smaller and less expensive sensor for temperature and humidity measurement.
- Low power consumption.
- Relative humidity and temperature measurement
- All calibration, digital output
- Excellent long-term stability
- No additional components
- Long-distance signal transmission
- Ultra-low power
- 4-pin package
- Completely interchangeable
