- HIH-4000 Series humidity sensor is designed for mass production of original equipment manufacturer (OEM)
- Designed for the user. Take advantage of this sensor's linear voltage output can be directly input to the controller or other
- Device. Generally only remove the 200μA current, HIH-4000 Series humidity sensor can be ideally
- For low leads, battery-powered systems. Interchangeability of sensors to reduce or eliminate the good of the OEM's
- Production calibration costs. Can provide a single sensor calibration data.
- HIH-4000 Series humidity sensor as a low cost, solderable single-line group
- Pieces (SIP) to provide quality instrument measuring the relative humidity (RH) sensor performance. RH sensor can be used in two
- Lead spacing between the assigned amount, which is a thermosetting plastic capacitive sensing element, the chip with
- A signal processing functions. Sensing element on the application of multi-layer structure of the adverse environmental factors such as humidity,
- Dust, dirt, oils and common environmental chemicals has the best resistance.

- *** Specifications include outside work area recommended by the test data.
- **** Specifications recommended only in terms of the work area.
- 1. Sensor should not be exposed in a condensing environment.
- 2. Exposure to liquid water will cause the sensor output indicates 0% RH.
- 3. Sensor is light sensitive devices. For best performance, the sensor should be shielded to prevent glare.
- 4. Exposure to> 90% RH environment can cause reversible drift of 3% RH.
- 5. Sensor connected to the electrostatic sensor should be protected, to a maximum of 15kV.
- 6. The sensor output is proportional to the supply voltage.
