Honeywell Temperature and Humidity Sensor, 4 Pins, ±2%RH Accuracy- HIH8000 Series - HIH8121-021-001

Accurately measure relative humidity and temperature levels with this digital sensor from Honeywell. It maintains its stability over long periods of time, so there's no need to regularly recalibrate the unit. The thermoset polymer capacitive sensing element is resistant to condensation, dust, dirt and oil, so it helps to prevent contaminants from affecting the unit's readings. This sensor has a sleep mode when not in use to reduce power consumption and maximise battery life for long-lasting performance.

Features & Benefits

• Wide operating temperature range of -40°C to +125°C for use in demanding conditions

• Temperature measurement accuracy of +0.5°C for precise results

Applications

• Air compressors

• Dehumidifiers

• Industrial incubators

• Grain drying systems

Where can I mount this sensor?

This sensor is designed for through-hole mounting onto a PCB for simple and secure installation.
