DescriptionDHT12 Temperature and Humidity Sensor is an upgraded version of DHT 11 Sensor and is more precise. DHT12 Sensor has both single bus communication and I2C communication as well. When used in single bus communication it is compatible to DHT11.Features of DHT12 SensorSuper compact sizeSuper low power consumptionSuper low voltage operationStandard I2C and 1-wire interface.Semi conductor technologySensing rangeTemperature : -20 ~ 60 CHumidity : 20-95 RHHumidity :Resolution : 0.1%RHRepeat : - 1%RHPrecision 25C @ - 5RHTemperature :Resolution : 0.1CRepeat : - 0.2CPrecision : 25C @ - 0.5CPower : DC 2.7-5.5VNormal current 1mAStandby current 60uASample cycle : > 2 secondsPin interface : 1.
