Honeywell HIH-4000 Series Humidity Sensor SIP 3 Pin
Honeywell HIH-4000 relative humidity sensor with near-linear voltage output, 4 to 5.8VDC supply and 3-pin SIP package for OEM use.
The Honeywell HIH-4000 Series Humidity Sensor SIP 3 Pin is a precision relative humidity sensor with a near-linear voltage output, designed for high-volume OEM applications. It is housed in a 3-pin SIP package for through-hole mounting.
Overview
The near-linear voltage output allows direct connection to a controller or other devices, which simplifies integration and reduces design complexity. With a typical current draw of 200µA, the sensor is suited to low-power and battery-operated systems. It has a fast response time and a maximum setting time of 70ms.
Construction and Performance
The sensing element is a laser-trimmed, thermoset polymer capacitive sensor with on-chip signal conditioning. Its multilayer construction provides resistance to wetting, dust, dirt, oils, and environmental chemicals. Tight sensor interchangeability helps reduce or eliminate OEM production calibration costs. The housing is moulded thermoset plastic.
