SHT20 Temperature & Humidity Sensor

• SHT20 Temperature & Humidity Sensor
• The SHT20 series of digital devices are widely used as humidity and temperature sensors.
• Humidity is measured using a capacitive sensor while temperature is measured using a band-gap sensor.
• The SHT2x sensors also contains a version 4 silicon chip with an amplifier, Analog to Digital converter, OTP memory and a digital interface.
• The SHT2x sensors are ideal for both high and low volume applications. The devices are fully calibrated, and directly provide final measurements as a digital value.
• There are only four pins that need to be hooked up. One for VCC, one for GND, and two data lines for I2C communication. Connect the SDA and SCL lines directly to the SDA and SCL lines broken out on the Arduino headers.

Pin Configuration

• VCC: Module power supply – connect to 3.3V pin
• GND: Ground – connect to a ground pin
• SDA:Serial Data Input/Output for the I2C protocol
• SCL:Serial Clock Input for I2C the protocol
