World’s Smallest Capacitive Humidity Sensor

P-14Innovative Sensor Technology has added the World’s smallest capacitive humidity sensor to its line of thin-film sensors. Measuring just 1.85 mm x 1.85 mm, the P14 202 is capable of measuring from 0 to 100% relative humidity in a temperature range of -50°C to +150°C. The assembly of the sensor is fully automated, and the contacts are designed for soldering and bonding.

Linearity Error and Hysteresis Less Than ±1.5% RH
The employment of high quality materials and manufacturing techniques has allowed IST to produce a thin-film humidity sensor with miniature dimensions that features excellent linearity and hysteresis behavior. The P14 202 offers a linearity error of < ±1.5% RH (15 … 90% RH at 23°C, after one point calibration), and hysteresis of < ±1.5% RH in a three hour cycle between 20% and 80% RH.

Unique Sensor Applications
The extraordinarily small volume and surface area of IST’s P14 202 lends itself to unique solutions where space is limited or “smaller is better”. Two such applications include white goods/appliances, and mobile devices such as cell phones.
