Additional Details

The RPM871-H14E2 integrates a PIN photodiode, a preamplifier, and a demodulation circuit into a single molded package. The AGC circuit automatically adjusts the receiver's sensitivity to maintain a stable output signal even with variations in the received infrared signal strength. This module is designed to be highly resistant to noise from fluorescent lights, incandescent lights, and other sources of interference. The output signal is typically a logic-low signal when an infrared signal is received and a logic-high signal when no signal is present. The peak wavelength is 940nm. The supply current is typically 0.7mA and is RoHS compliant.
