HTU20D

HTU20D is a new digital humidity sensor with temperature output of MEAS.This sensor provides calibrated, linearized signals in digital, I2C format. HTU20D digital humidity sensors are dedicated humidity and temperature plug-n-play transducers for OEM applications (where reliable and accurate measurements are needed).The resolution of this digital humidity sensor can be changed by command (8/12bit up to 12/14bit for RH/T). This Device is available from www.ncd.io

How to Use the HTU20D Arduino Library

The HTU20D has a number of settings, which can be configured based on user requirements.

1.Resolution setting:The following command is used to set the resolution of sensor for humidity and temperature.

         htu.setResolution(RESOLUTION_0);             // RH: 12 bit, Temp: 14 bit

2.Voltage setting:The following command is used to set the voltage.

          htu.setVoltage(VOLTAGE_OK);                  // VDD OK

3.Heater status:The following command is used to set the heater enable.

          htu.setHeaterStatus(HEATER_ENABLE);          // On-chip Heater Enable

4.OTP status:The following command is used to set the OTP status as Disable.

          htu.setOTPStatus(OTP_DISABLE);               // OTP Reload Disable

5.Temperature mode:The following command is used to measure the temperature and set NO HOLD Master Mode.

          htu.setTempMode(TEMP_NO_HOLD);               // Measure Temperature, No Hold Master Mode

6.Humidity mode:The following command is used to measure the humidity and set NO HOLD Master Mode.

           htu.setHumidityMode(HUMIDITY_NO_HOLD);       // Measure Humidity, No Hold Master Mode
