SEN0546

SEN0546 is an I2C temperature & humidity sensor (stainless steel shell). 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. We are excited to announce a significant performance upgrade for I2C digital temperature & humidity sensor. The latest version now integrates a new-generation chip, delivering a major improvement in measurement accuracy.
