The HTU21D is a low-cost, easy to use, highly accurate, digital humidity and temperature sensor. This sensor is ideal for environmental sensing and data logging and perfect for a weather stations or humidor control systems. All you need is two lines for I2<\/sup>C communication and you\u2019ll have relative humidity readings and very accurate temperature readings as a bonus!<\/p>\n\n There are only four pins that need to be hooked up in order to start using this sensor in a project. One for VCC, one for GND, and two data lines for I2<\/sup>C communication. This breakout board has built in 4.7k pull up resistors for I2<\/sup>C communications. If you\u2019re hooking up multiple I2<\/sup>C devices on the same bus, you may want to disable these resistors.<\/p>\n\n Note:<\/strong> Full drops of water can damage the sensor. We recommend wrapping the board in Teflon\/irrigation tape for extreme conditions where water droplets may find their way onto the sensor.<\/p>\n\n Features:<\/strong><\/p>\n\n
