In addition to measuring CO2, the SCD41 can also measure temperature and humidity. The sensor communicates through an I2C address and can be powered from 2.4V up to 5.5V. You can connect it to both ESP32 or ESP8266 and duino Uno or Raspberry Pi. You can connect the module via a pin comb or our uŠup connector (JST-SH). The module itself also has its own pull-up resistors for the I2C bus. The module can be attached with 4 2.2x5mm screws.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size:18px;font-family:Times New Roman;\"\u003eSpecifications:\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:18px;font-family:Times New Roman;\"\u003ePower supply: 2.4-5.5V\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:18px;font-family:Times New Roman;\"\u003eMeasurement range: 400 - 5000ppm\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:18px;font-family:Times New Roman;\"\u003eAccuracy: ± (40 ppm + 5%) of the measured value\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:18px;font-family:Times New Roman;\"\u003eBus: I2C\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:18px;font-family:Times New Roman;\"\u003eResponse: 60s\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:18px;font-family:Times New Roman;\"\u003eRange (temperature): -10 - +60 ° C\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:18px;font-family:Times New Roman;\"\u003eAccuracy (temperature): ± 0.8 ° C (for range 15 - 35 ° C)\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:18px;font-family:Times New Roman;\"\u003eRange (humidity): 0 - 100% RH\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:18px;font-family:Times New Roman;\"\u003eAccuracy (humidity): ± 6% RH (15 ° C - 35 ° C, 20% RH - 65% RH)\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:18px;font-family:Times New Roman;\"\u003eDimensions: 21x21x8mm\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"font-size:18px;font-family:Times New Roman;\"\u003eWeight: 2.5g\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size:18px;font-family:Times New Roman;color:#00ccff;\"\u003eBrand: LaskaKit\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size:18px;font-family:Times New Roman;\"\u003eLink to Specifications: https:\/\/github.com\/LaskaKit\/SCD41-CO2-Sensor\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"width:750px;\" src=\"https:\/\/ae01.alicdn.com\/kf\/Sc0f5e678a6f040888d8b015856ef23f0U.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"width:750px;\" src=\"https:\/\/ae01.alicdn.com\/kf\/Sbf51280d757942a68ed945b0ae1b1190L.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\u003c\/div\u003e\r\n","brand":"East Supplier Platform","offers":[{"title":"SCD40 Module","offer_id":46589622911199,"sku":"1005005061351244-SCD40 Module","price":28.18,"currency_code":"USD","in_stock":true},{"title":"SCD41 Module","offer_id":46589622943967,"sku":"1005005061351244-SCD41 Module","price":35.74,"currency_code":"USD","in_stock":true},{"title":"SCD41 Module F","offer_id":46589622976735,"sku":"1005005061351244-SCD41 Module F","price":47.64,"currency_code":"USD","in_stock":true},{"title":"SCD40 Sensor","offer_id":46589623009503,"sku":"1005005061351244-SCD40 Sensor","price":23.34,"currency_code":"USD","in_stock":true},{"title":"SCD41 Sensor","offer_id":46589623042271,"sku":"1005005061351244-SCD41 Sensor","price":30.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0503\/6412\/1244\/files\/S5fefa8d758814d118424c983bc75ef7dL.webp?v=1734479250","url":"https:\/\/eastsupplier.cn\/products\/scd40-scd41-gas-sensor-module-detects-co2-carbon-dioxide-temperature-and-humidity-in-one-sensor-i2c-communication","provider":"EastSupplier Platform","version":"1.0","type":"link"}
