## Description

This I2C digital temperature & humidity sensor offers high accuracy of ±3.0RH% for humidity and ±0.5°C for temperature and features a user-programmable humidity & temperature alarm function.Its housing is made of 304 stainless steel to ensure good impact resistance, heat resistance, low temperature, and chemical resistance. The sensor output is designed as DuPont 2.54 connector for easy wiring. Also, there are two built-in 4.7K pull-up resistors and one 100nF filtering capacitor so the sensor can be directly used with microcontrollers like Arduino. This temperature & humidity sensor can be applied to electronic, medical, automotive, industrial, weather, and other fields, including home appliances like HVAC, dehumidifiers and refrigerators, testing & inspection equipment, and other relevant temperature & humidity measurements and controls.
