This ensures that the sensors are fully interchangeable, with no recalibration or software changes required.The Si7021 is available in a 3x3 mm DFN package and is reflow solderable.It can be used as a hardware- and software-compatible drop-in upgrade for existing Featuring precision sensing over a wider range and lower power consumption.The Si7021 offers an accurate, low-power, factory-calibrated digital solution ideal for measuring humidity, dew-point, and temperature, in applications ranging from HVAC\/R and asset tracking to industrial and consumer platforms.\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003eSpecification:\u003c\/strong\u003e\u003c\/span\u003ePower supply : 3-5VRelative humidity: ± 3% RH (max), 0-80% RHTemperature: ±0.4°C (max), -10 to 85°COperating range: 0 to 100% RHOperating range: Up to -40°C to +125 °CWide operating voltage: 1.9V - 3.6VLow power consumption: 150 μA active currentStandby current: 60 nASize: 1.3*1cm\/0.51*0.39\"\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/span\u003eHVAC\/RThermostats\/humidistatsRespiratory therapyWhite goodsIndoor weather stationsMicro-environments\/data centersAutomotive climate control and defoggingAsset and goods trackingMobile phones and tablets\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003ePackage includes:\u003c\/strong\u003e\u003c\/span\u003e1 x GY-21 Humidity Sensor\u003c\/span\u003e\u003cdiv id=\"imgBox\"\u003e,,,,\u003c\/div\u003e","brand":"Burnett Canada","offers":[{"title":"Default Title","offer_id":39194068877463,"sku":"C122-1184749","price":24.34,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0490\/2171\/4583\/products\/1184749.jpg?v=1613741910","url":"https:\/\/burnettcanada.ca\/fr\/products\/c122-1184749-gy-21-htu21d-humidity-sensor-with-i2c-interface-geekcreit-for-arduino-products-that-work-with-official-arduino-boards","provider":"Burnett Canada ","version":"1.0","type":"link"}
