OTP-N538U Thermopile Non-Contact Infrared Temperature Sensor Previous 
GY-213V-HTU21D Temperature Humidity Sensor Module is a digital humidity and temperature sensor module for environmental sensing and data logging. It supports I2C communication and uses only four pins for basic operation. The module is suitable for projects that require relative humidity readings and temperature readings through a simple digital interface. It is designed for low-cost and easy use in electronics and robotics applications. The board includes built-in 4.7k pull-up resistors for I2C communications. Full drops of water can damage the sensor.
