Honeywell Relative Humidity Sensors are configured with integrated circuitry to provide on-chip signal conditioning delivering a linear output voltage of ±2% RH. These sensors contain a capacitive sensing die set in thermoset polymers that interacts with platinum electrodes. The laser trimmed sensors have an interchangeability of ±5% RH and achieve a ±2% RH accuracy with calibration, with stable, low drift performance. Packages are chemically resistant and operate in ranges of -40 °C to 85° C (-40°F to 185°F) to accommodate harsh environments.
