Description: the humidity and temperature Sensor is an Arduino-compatible sensor board that carries an SHT21 digital humidity and temperature sensor from Sensirion. It has a 4-pin interface that can communicate directly with the analog pins on the Arduino. Relative humidity operating range: 0-100% RH. Because of the sensor¡¯s tiny size, it has incredibly low power consumption, making it suited for virtually any application.
. Relative humidity Response Time of 8 sec tau 63%. Specifications: * energy consumption: 80 uw at 12 bit, 3V, 1 measurement/s * Relative Humidity operating range: 0-100% RH * Relative Humidity resolution of 003% * relative humidity response time of 8 sec tau 63% * Temperature operating range: -40 to +125¡æ * Temperature resolution of 0

5% rh / year response time: 5 s package inlcuded: 1*htu21d temperature humidity sensor breakout Module The new generation of htu21d temperature and humidity sensors has set new standards in terms of size and intelligence: it embeds a double row, flat, leadless DFN package for reflow, with a 3x3mm bottom surface and 1.
HiLetgo HTU21D Temperature Humidity Sensor Breakout Module I2C IIC 1.5V-3.6V Replace SHT15 Compatible to SHT20 SHT21 #ad - 1mm height. Sensor output calibrated digital signal, standard I2C format. Diversified output, wide operating voltage range, also it have high temperature accuracy and humidity accuracy. Designed for low power and small volume applications, the HTU21 Series modules are characterized by good quality, strong anti-interference ability, and high cost performance.
If you're hooking up multiple I2C devices on the same bus, you may want to disable these resistors. This sensor is ideal for environmental sensing and data logging and perfect for a weather stations or humidor control systems. The tiny volume 3x3mm, fast response, low power consumption. At the same time, htu21d can be fully compatible with SHT20 and SHT21 in Switzerland, pin to pin can be realized on hardware pins, without modifying the circuit board.
