Honeywell Humidity Sensor, 4.17mm, 3-Pin SIP - HIH-4000-002
This humidity sensor from Honeywell is specifically designed for high-volume original equipment manufacturer (OEM) users. The sensor is frequently installed in equipment that requires strict monitoring of humidity levels, such as sensitive medical equipment or meteorological instruments. It has a moulded thermoset plastic housing, so it's able to withstand light impacts. The sensing element's multilayer construction also provides excellent resistance to moisture as well as oils, dirt, dust and chemicals, making it a good choice for use in harsh environments.
Features & Benefits
• Single in-line package (SIP) type for simple mounting onto printed circuit boards (PCBs)
• Analogue interface for easy pressure readings
• Low current draw of 200μA, making it suitable for low-drain, battery-operated systems
• Wide operating temperature range of -40°C to +85°C for use in a variety of conditions
Applications
• Heating, ventilation and air conditioning (HVAC) equipment
• Medical industry
• Refrigeration equipment
Where on the PCB should I install a humidity sensor?
The humidity sensor should be placed in an area of the PCB that's as far away as possible from any heat-generating components. This reduces the risk of inaccurate readings caused by differences in temperature.
