The The MikroElektronika's Humidity Click is a compact add on board used to sense the amount of water vapour in the air. This board features the HIH-5030, an analogue output relative humidity sensor from Honeywell Sensing and Productivity Solutions. The HIH-5031 is a covered, condensation resistant, integrated circuit humidity sensor that is factory fitted with a hydrophobic filter allowing usage in many condensing environments. The RH sensor uses a laser trimmed, thermoset polymer capacitive sensing element with on chip integrated signal conditioning, providing enhanced stability, accuracy, and response time over the entire humidity range of 0%RH to 100%RH. However, the choice of signal processing is up to the user

Low power consumption
High precision and performance
Enhanced accuracy and response time over the entire humidity range
Chemically resistant
Possibility of signal processing in analogue and digital form
