Pir Sensor RD-623

Product Description:Pyroelectric infrared sensors use the characteristics of temperature changes to detect infrared radiation, and use dual compensation methods to suppress the interference caused by temperature changes, and improve the stability of the sensor. Application wide pan, such as safety devices, burglar alarms, door sensors, automatic lights, intelligent toys.Features1. High sensitivity and superior signal-to-noise ratio2. The dual compensation structure is adopted to effectively resist the interference of the external environment3. Components and amplifiers are all encapsulated in TO-5 , which saves users the time for circuit design and mounting. Excellent anti-interference performance.4. The circuit package since the entire package in the metal within the apparatus, the electromagnetic shielding effect is better5. The interference filter has a high cut-off depth and a strong ability to resist white light
