Honeywell HIH8120 Digital Temperature and Humidity Sensor SIP

The Honeywell HIH8120-021-001 is a fully digital, combined relative humidity (RH) and temperature sensor, delivering highly accurate environmental monitoring. Engineered for precision, it provides an industry-leading humidity accuracy of ±2.0% RH and a temperature accuracy of ±0.8°C. The sensor integrates a true temperature-compensated digital output, ensuring reliable and stable readings across a wide operational range.

This device is celebrated for its exceptional long-term stability, maintaining a drift of just 1.2% RH over five years, which minimises the need for recalibration and ensures dependable performance in long-term deployments. Its energy-efficient design and high-resolution output make it an ideal choice for power-sensitive and data-critical applications.
