I2C CHT8305C Temperature and Humidity Sensor

This is a digital I2C temperature and humidity sensor from DFRobot. The sensor measures humidity with a tolerance of ±3.0RH% and temperature with ±0.5℃. The sensor also has a user-programmable alarm function for humidity and temperature. The case is made of 304 stainless steel, ensuring good impact resistance, thermal and chemical stability. This digital I2C temperature and humidity sensor offers high accuracy of ±3.0%RH for humidity and ±0.5℃ for temperature and has a user-programmable alarm function for humidity and temperature. The sensor output is configured as a DuPont 2.54 connector for easy wiring. There are two built-in 4.7K pull-up resistances and one 100nF filter capacitor, so that the sensor can be used directly with microcontrollers such as Arduino.
