SHT20 I2C Temperature And Humidity Sensor With Waterproof Probe For Environmental Monitoring
 

The SHT20 I2C Temperature and Humidity Sensor is a high-accuracy environmental sensing module equipped with a waterproof probe for reliable operation in humid, outdoor, and industrial environments. Built around the Sensirion CMOSens SHT20 sensor chip, the module combines temperature and humidity sensing with signal conditioning, analog-to-digital conversion, memory, and digital processing in a single compact device. The dual waterproof protection design of the probe enhances durability and enables accurate measurements in demanding applications where moisture resistance is essential.

Compared with earlier SHT1x and SHT7x sensor families, the SHT20 delivers improved reliability, long-term stability, and measurement performance. The module includes an onboard 10k pull-up resistor and 0.1uF filter capacitor, allowing direct connection to Arduino, ESP32, Raspberry Pi, STM32, and other microcontroller platforms through the I2C interface. Its robust waterproof construction and precision sensing capabilities make it suitable for weather monitoring, smart agriculture, industrial automation, environmental data logging, and IoT-based monitoring systems.
