The HN911 heat releasing electric infrared probe model is a sensing device which consists of the heat releasing electric infrared sensor, amplifier signal process circuit, time delay circuit and high/low LEV output circuit. It characterizes high sensitivity, high anti-noise ability, low temperature resistance and convenient use, etc, which is used to detect the infrared ray energy which is emitted by human bodies, it is suitable for the detection alarm system of human movement.The internal circuit of the HN911 heat releasing electric infrared probe module is shown in the figure.
