The post DHT11 temperature and humidity sensor module For Arduino and Raspberry Pi DHT-11 appeared first on Absolute Native Electronics.
]]>Compared to the DHT22, this sensor is less precise, less accurate and works in a smaller range of temperature/humidity, but its smaller and less expensive
Comes with a 4.7K or 10K resistor, which you will want to use as a pullup from the data pin to VCC.
Technical Details
Low cost
3 to 5V power and I/O
2.5mA max current use during conversion (while requesting data)
Good for 20-80% humidity readings with 5% accuracy
Good for 0-50°C temperature readings ±2°C accuracy
No more than 1 Hz sampling rate (once every second)
Body size 15.5mm x 12mm x 5.5mm
4 pins with 0.1″ spacing
