{"product_id":"sparkfun-mikroe-temp-hum-9-click","title":"SparkFun MIKROE Temp\u0026Hum 9 Click","description":"\u003cp\u003eTemp-Hum 9 Click is a smart temperature and humidity sensing Click board�, packed with features that allow simple integration into any design. It can measure a wide range of temperature and relative humidity values with high accuracy. The SHTC3 sensors used on this Click board� offers the complete measurement system: capacitive RH sensor, bandgap thermal sensor, analog and digital data processing, and the I2C communication interface. Featuring a good reliability over time, high accuracy, and low hysteresis, it is an ideal solution to be used in various temperature and humidity related applications.\u003c\/p\u003e \u003cp\u003eTemp-Hum 9 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.\u003c\/p\u003e \u003cp\u003eTemp-Hum 9 Click can measure the humidity in the range from 0 to 100 %RH and temperature in the range from -40 � to +125 � with a typical accuracy of ±2 %RH and ±0.2 �. It consumes very low amount of power while operated, and it can output the conversion values directly in physical units, thanks to the CMOSens® manufacturing technology. Featuring high reliability and long-term stability, high Signal-to-Noise (SNR) ratio, good accuracy, and low power consumption, Temp-Hum 9 Click is an ideal solution for development of a range of different applications, including battery operated weather stations, thermostats and humidistats, microenvironment centers, respiratory therapy applications, air conditioners, and other similar applications.\u003c\/p\u003e \u003cp\u003eThe main component of Temp-Hum 9 Click is the SHTC3, a relative humidity and temperature sensor with I²C Interface, by Sensirion. This sensor IC integrates two very accurate sensing components: temperature sensor, and relative humidity sensor. By utilizing the proprietary CMOSens® manufacturing technology, this sensor integrates the complete temperature and humidity measurement system on chip. The output data is processed and compensated by the SHTC3 IC itself, requiring only basic conversion formulas to be applied within the firmware of the host microcontroller (MCU). These conversion formulas are given in the SHTC3 datasheet, and provide readings in °C and %RH, directly.\u003c\/p\u003e \u003cp\u003eThe SHTC3 incorporates an accurate bandgap temperature sensor, which can measure the temperature in the range between -40°C and 125°C while retaining accuracy of ±0.8°C, typically. The accuracy is even greater if the range is narrowed down: when used over the range between 0°C and 60°C, the typical accuracy is ±0.2°C. Also, the repeatability of the temperature measurement is very good, in the range of 0.1°C. The SHTC3 sensor IC can be reliably used for prolonged periods of time, as it has a very low thermal drift of less than 0.02°C per year.\u003c\/p\u003e \u003cp\u003eAfter the measurement has been converted by high-precision ADC, it is fed to a logic back-end which applies factory-calibrated correction and converts the raw data into a compensated value. By applying a simple conversion formula, the temperature measurement can be read directly in �. Note however, that the sensor will take some time to accommodate to the ambient temperature, especially if the temperature changes quickly, considering the thermal conductivity of the PCB itself. However, the Click board� surface is not very large, resulting in lower thermal inertia.\u003c\/p\u003e \u003cp\u003eThe humidity sensor is a capacitor-based sensor which changes the capacitance proportionally to the relative humidity. However, the capacitance of this sensor is affected by changes of the ambient temperature, as well. The datasheet of the SHTC3 offers a map of the RH accuracy at different temperatures, covering a range of different values. The RH sensor accuracy varies in the range between ±2% and ±4%, depending on the measurement conditions. This table can be used to check the exact accuracy for some specific � and %RH conditions.\u003c\/p\u003e \u003cp\u003eAfter the measurement has been converted by high-precision ADC, it is fed to a logic back-end which applies factory-calibrated correction and converts the raw data into a compensated value. By applying a simple conversion formula, the temperature measurement can be read directly in %RH. Note that capacitor-based humidity sensors commonly suffer from a small hysteresis, which may occur if the sensor is used in very humid conditions for prolonged periods of time. However, this hysteresis is not irreversible. The SHTC3 datasheet specifies that its hysteresis should stay within the range of ±1 %RH.\u003c\/p\u003e \u003cp\u003eTemp-Hum 9 Click uses the I2C communication interface. It has pull-up resistors connected to the mikroBUS� 3.3V rail. A proper conversion of logic voltage levels should be applied before the Click board� is used with MCUs operated with 5V.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eInterface: I\u003csup\u003e2\u003c\/sup\u003eC\u003c\/li\u003e \u003cli\u003eCompatibility: mikroBUS�\u003c\/li\u003e \u003cli\u003eDimensions: 42.9 x 25.4mm\u003c\/li\u003e \u003cli\u003eInput Voltage: 3.3V\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/9\/0\/8\/6\/2\/Schematic-19857-MIKROE_Temp_Hum_9_Click.pdf\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/4\/3\/9\/f\/3\/SHTC3.pdf\"\u003eSHTC3 Datasheet\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/www.mikroe.com\/mikrosdk\"\u003emikroSDK\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/github.com\/MikroElektronika\/mikrosdk_click_v2\/tree\/master\/clicks\/temphum9\"\u003eGitHub\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e","brand":"sparkfun-10","offers":[{"title":"Default Title","offer_id":40331958714453,"sku":"19857:SEN-19857:spark","price":2190.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/19857_-_MIKROE_Temp_Hum_9_Click_2.jpg?v=1663616169","url":"https:\/\/www.tanotis.com\/products\/sparkfun-mikroe-temp-hum-9-click","provider":"Tanotis","version":"1.0","type":"link"}
