I2C Digital Temperature & Humidity Sensor

SKU: SEN0546

The I2C Digital Temperature & Humidity Sensor is engineered for high precision measurement of temperature and humidity, boasting an accuracy rating of ±3.0RH% for humidity and ±0.5℃ for temperature. It includes user-programmable alarm functions for both humidity and temperature, empowering users to set specific thresholds for alerts. Constructed with a robust 304 stainless steel housing, the sensor is designed to withstand impact, heat, low temperatures, and chemical exposure. The output uses a DuPont 2.54 connector for straightforward wiring, making it compatible with microcontrollers such as Arduino. Furthermore, it is equipped with two built-in 4.7K pull-up resistors and a 100nF filtering capacitor, ensuring smooth integration and reliable performance. Ideal for applications demanding precise environmental monitoring, this sensor merges accuracy with ease of use, making it a perfect choice for enthusiasts and professionals alike.
