Please i need help in this question for sensor instrumentation course

1. * Humidity sensor is used sense the amount of humidity ( presence of water in air).

* application of Humidity Sensor:

* Humidity sensors are decided by sensing materials like Ceramic, semiconductor, and polymer materials

* RH- Relative Humdity

* Some of the Commercial humidity sensor are H7625, H7626

* Humidity parameter are RH , susbtrate, sensed parameter, Hysterisis, Linearity, Temperature range,

-10 F to 160F
