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.
