Simply connect the first pin on the left to 3-5V power, the second pin to your data input pin and the right most pin to ground. Although it uses a single-wire to send data it is not Dallas One Wire compatible! If you want multiple sensors, each one must have its own data pin!

Features:

• Low cost
• 3 to 5V power and I/O
• 1-1.5mA measuring current
• 40-50 uA standby current
• 2.5mA max current use during conversion (while requesting data)
• Good for 0-100% humidity readings with 2-5% accuracy
• Good for -40 to 80°C temperature readings ±0.5°C accuracy
• No more than 0.5 Hz sampling rate (once every 2 seconds)
• Body size 27mm x 59mm x 13.5mm (1.05″ x 2.32″ x 0.53″)
• 4 pins, 0.1″ spacing

Feature & Application:

• High precision
• Capacitive type
• Full range temperature compensated
• Relative humidity and temperature measurement
• Calibrated digital signal
• Outstanding long-term stability
• Extra components not needed
• Long transmission distance, up to 100 meters
• Low power consumption
• 4 pins packaged and fully interchangeable
