{"product_id":"sparkfun-mikroe-hvac-click","title":"SparkFun MIKROE HVAC Click","description":"\u003cp\u003eMIKROE HVAC Click is a compact add-on board that contains Sensirionâ��s next-generation miniature CO2 sensor. This board features the SCD41, a carbon dioxide sensor build on the photoacoustic sensing principle, and Sensirionâ��s patented PASens�® and CMOSens�® technology to offer high accuracy at a minor form factor. On-chip signal compensation is realized with the build-in humidity and temperature sensor. It operates within a specified range from 400 to 5,000 ppm, configurable through the I2C interface with a single shot mode supported. This Click boardâ�¢ is also suitable for indoor air quality applications using an additional \u003ca href=\"https:\/\/www.sparkfun.com\/products\/15103\"\u003eSPS30\u003c\/a\u003e that allows smart ventilation systems to regulate ventilation in the most energy-efficient and human-friendly way, maintaining low CO2 concentration for a healthy, productive environment.\u003c\/p\u003e \u003cp\u003eHVAC Click as its foundation uses the SCD41, a Sensirionâ��s next-generation miniature CO2 sensor. This carbon dioxide sensor builds on the photoacoustic sensing principle and Sensirionâ��s patented PASens�® and CMOSens�® technology to offer high accuracy at a minor form factor. It operates within a specified range from 400 to 5,000 ppm, configurable through the I2C interface with a low-power single-shot mode supported to reduce noise levels, i.e., on-demand measurement.\u003c\/p\u003e \u003cp\u003eThe SCD41 features on-chip signal compensation to counteract pressure and temperature effects. Feeding the SCD41 with the pressure or altitude enables the highest accuracy of the CO2 output signal across an extensive pressure range. Setting the temperature offset improves the accuracy of the relative humidity and temperature output signal. Note that the temperature offset does not impact the accuracy of the CO2 output.\u003c\/p\u003e \u003cp\u003eHVAC Click communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Standard mode operation with a clock frequency up to 100kHz. Furthermore, this Click boardâ�¢ is suitable for indoor air quality applications using an additional \u003ca href=\"https:\/\/www.sparkfun.com\/products\/15103\"\u003eSPS30\u003c\/a\u003e, a Particulate Matter (PM) sensor from Sensirion, with the help of which the HVAC Click in the most energy-efficient and human-friendly way maintains a low CO2 concentration for a healthy, productive environment.\u003c\/p\u003e \u003cp\u003eThe measurement principle of the \u003ca href=\"https:\/\/www.sparkfun.com\/products\/15103\"\u003eSPS30\u003c\/a\u003e is based on laser scattering, which, together with high-quality, enables precise measurements from its first operation and throughout its lifetime of more than ten years. In addition, the \u003ca href=\"https:\/\/www.sparkfun.com\/products\/15103\"\u003eSPS30\u003c\/a\u003e provides the possibility of using both I2C and UART interfaces where the communication interface selection can be made by positioning SMD jumpers labeled COMM SEL to an appropriate position. Note that all the jumpers' positions must be on the same side, or else the Click boardâ�¢ may become unresponsive. Also, to activate I2C communication, the JP4 jumper must be populated.\u003c\/p\u003e \u003cp\u003eThis Click boardâ�¢ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it allows both 3.3V and 5V capable MCUs to use the communication lines properly. In addition, however, the Click boardâ�¢ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.\u003c\/p\u003e \u003cp\u003eHVAC Click is supported by a \u003ca href=\"https:\/\/www.mikroe.com\/mikrosdk\"\u003emikroSDK\u003c\/a\u003e compliant library, which includes functions that simplify software development.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e The PM2.5 Sensor Module \u003ca href=\"https:\/\/www.sparkfun.com\/products\/15103\"\u003eSPS30\u003c\/a\u003e does not come in the same package with this Click boardâ�¢.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eInterface: I\u003csup\u003e2\u003c\/sup\u003eC, UART\u003c\/li\u003e \u003cli\u003eCompatibility: mikroBUSâ�¢\u003c\/li\u003e \u003cli\u003eDimensions: 42.9 x 25.4mm\u003c\/li\u003e \u003cli\u003eInput Voltage: 3.3V or 5V\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\/2\/b\/7\/6\/Schematic-18972-HVAC_Click.pdf\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/a\/d\/a\/b\/5\/SCD41_Datasheet.pdf\"\u003eSCD41 Datasheet\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/libstock.mikroe.com\/projects\/view\/3875\/hvac-click\"\u003eLibstock\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/www.mikroe.com\/mikrosdk\"\u003emikroSDK\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eVideos\u003c\/strong\u003e\u003c\/p\u003e \u003cdiv class=\"flex-video-wrap clearfix\"\u003e \u003cdiv class=\"flex-video widescreen img\"\u003e \u003ciframe src=\"https:\/\/www.youtube.com\/embed\/zzlh1oGii1Q\/?autohide=1\u0026amp;border=0\u0026amp;wmode=opaque\u0026amp;enablejsapi=1\" frameborder=\"0\" allowfullscreen width=\"560\" height=\"315\"\u003e\u003c\/iframe\u003e \u003c\/div\u003e \u003c\/div\u003e","brand":"sparkfun-10","offers":[{"title":"Default Title","offer_id":40054694379605,"sku":"18972:SEN-18972:spark","price":7475.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/18972_-_HVAC_Click_2.jpg?v=1651343121","url":"https:\/\/www.tanotis.com\/products\/sparkfun-mikroe-hvac-click","provider":"Tanotis","version":"1.0","type":"link"}
