Honeywell HIH-4000 Series Humidity Sensor, Analogue Output, Through Hole Mount, Analogue, ±3.5%RH, 3 Pins

The HIH-4000 series has been specifically designed for use in high volume OEM (Original Equipment Manufacturer) applications. These sensors utilise a near linear voltage output making direct input to a controller or other devices possible. They are ideally suited for low drain, battery operated systems with a typical current draw of only 200 μA. Potential Applications:Refrigeration equipmentHVAC equipmentMedical equipmentDryingMeteorologyBattery-powered systemsOEM assemblies

Features:Moulded thermoset plastic housingNear linear voltage output vs %RHLaser-trimmed interchangeabilityEnhanced accuracy, fast responseFast response timeStable, low drift performanceChemically resistant

This humidity sensor from Honeywell uses a clever SIP (system-in-package) design to keep it compact. Its small size of 4.17 (length) by 2.03mm (width) means it fits in where space is tight. The sensor is a highly efficient and accurate component. It's laser-trimmed and uses a capacitive sensing element and integrated signal conditioning for a quick and reliable response. The linear voltage output draws a current of just 200μA (microamps), making it a low-power component that's well-suited to battery-operated devices. This humidity sensor has a moulded and layered thermoset plastic case to make it chemical, oil and dust resistant for a long service life.

• Through-hole mounting for quick and secure installation on PCBs (printed circuit boards)
• Wide operating temperature range of -40°C to +85°C for use in extreme conditions or outdoors
• Works with supply voltages between 4 and 5.8V for greater flexibility

• OEM (original equipment manufacturer) assemblies
• Refrigeration and HVAC (heating, ventilation and air conditioning) equipment
• Measurement and control systems

This device is calibrated at 5V DC and +25ºC, ready for immediate installation in your controller or device under normal conditions.
