Silicon Labs SI7021-A20-IM is a high-accuracy, low-power digital humidity and temperature sensor. This component offers a ±3% RH accuracy across a 0 to 100% RH range, with a temperature sensing range of -40°C to 125°C. Communication is established via the I2C serial interface, providing 12-bit resolution for both humidity and temperature readings. The device features a fast 18-second response time for humidity measurements. Designed for surface mounting, it is supplied in a compact 6-DFN (3x3) package with an exposed pad for enhanced thermal performance. The operating voltage range is 1.9V to 3.6V. This sensor is widely utilized in industrial automation, consumer electronics, and HVAC systems.
