new design DHT22 AM2302 temperature and humidity sensor

new design DHT22 AM2302 temperature and humidity sensor

Features:

• Unique 1Wire interface requires only one port pin for communication. Multidrop
• capability simplifies distributed temperature sensing applications. Requires no
• external components
• Operating temperature range:-55°C to +125°C (-67F to +257F), ±0.5°C accuracy
• from -10 °C to +85°C
• Can be powered from data line. Power supply range is 3.0V to 5.5V
• Thermometer resolution is programmable from 9 to 12 bits.
• Size of Sheath:6*30mm

Application:

The DS18B20 Digital Thermometer provides 9 to 12bit (configurable) temperature

readings which indicate the temperature of the device. Information is sent to/from the

DS18B20 over a 1Wire interface, so that only one wire (and ground)needs to be

connected from a central microprocessor to a DS18B20. Power for reading, writing,

and performing temperature conversions can be derived from the data line itself with no

need for an external power source.

Because each DS18B20 contains a unique silicone serial number, multiple DS18B20s

can exist on the same 1Wire bus. This allows for placing temperature sensors in many

different places. Applications where this feature is useful include HVAC environmental

controls, sensing temperatures inside buildings,equipment or machinery, and process

monitoring and control.
