NS312 Pyroelectric Infrared Sensor

The NS312 is a pyroelectric infrared sensor that integrates a digital intelligent control circuit and a human detection sensing element within an electromagnetic shielding cover. The sensing element couples detected human motion signals to the internal smart integrated circuit via a very high-impedance differential input circuit. Signals are converted by an ADC and fully processed on-chip, resulting in high/low level output. Designed for human motion detection, it features low power consumption, high interference immunity, and excellent stability.
