It also comes in a significantly smaller r size as compared to the former 2 sensors.\u00a0The Si7021 has \u00b10.4 \u00b0C temperature accuracy at a range of -10 to +85 \u00b0C\u00b1 and 3% relative humidity measurements with a range of 0\u009680% RH. This  is perfect for environmental monitoring projects and uses the I2C interface for data transfer which makes it compatible with the majority of available microcontrollers.<\/p>\n<p><span style=\"color: #000000;\">The Si7021  offer 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.\u00a0e.
