Battery-powered systems
OEM assemblies
The HIH-3610 Series humidity sensor is designed specifically for high
volume OEM (Original Equipment Manufacturer) users. Direct input to a
controller or other device is made possible by this sensor's linear voltage
output. With a typical current draw of only 200
A, the HIH-3610 Series is
ideally suited for low drain, battery operated systems. Tight sensor
interchangeability reduces or eliminates OEM production calibration costs.
Individual sensor calibration data is available.
The HIH-3610 Series delivers instrumentation-quality RH (Relative
Humidity) sensing performance in a low cost, solderable SIP (Single In-line
Package). Available in two lead spacing configurations, the RH sensor is a
laser trimmed thermoset polymer capacitive sensing element with on-chip
integrated signal conditioning. The sensing element's multilayer
construction provides excellent resistance to application hazards such as
wetting, dust, dirt, oils, and common environmental chemicals.

Notes:
1. Extended exposure to
90% RH causes a reversible shift of 3% RH.
2. This sensor is light sensitive. For best results, shield the sensor from bright light.
