Relative Humidity Sensor
Proprietary humidity sensitive polymer is applied for our relative humidity sensors. Thermistor is combined in HSU series
assembly to be capable of temperature measurement.
Features
HIS-04/05, HSU-04 05 are our new line up of small sized Humidity sensors
1 Humidity detection performance is improved.
Especially lower humidity sensing is expended.
2 Smaller in size
New sensor is 50% or less volume compared with our conventional sensor.
Driver mounted sensor unit with chip thermistor is also as small as 62%.
3 Price competitive
Price is competitive after improvement of performance and volume.
4 Easy application
DC5V input for DC out put, chip thermistor for temperature measurement are involved in HSU series.
