Hw416b Pir Sensor Datasheet Better ((hot))

The HW416B (often interchangeably referred to as the HC-SR501) is a versatile passive infrared (PIR) motion sensor widely used in DIY electronics and security systems. It detects motion by measuring changes in infrared radiation emitted by objects like humans or animals. Key Technical Specifications Specification Operating Voltage DC 4.5V to 20V (5V recommended) Static Current Output Signal Digital (High 3.3V / Low 0V) Detection Range 3 to 7 meters (Adjustable) Detection Angle < 100° to 120° cone angle Delay Time 5 seconds to 300 seconds (Adjustable) Operating Temp -15°C to +70°C PIR Motion Sensor HW416B - Tayda Electronics

operates within a flexible voltage range and provides a simple digital signal output Handson Technology Operating Voltage: DC 4.5V to 20V. Static Current: Less than 65µA (ultra-low power consumption). Output Signal: High (3.3V) when motion is detected; Low (0V) when idle. Detection Range: Adjustable from approximately 3 to 7 meters. Detection Angle: Less than 110° to 120° cone. Delay Time: Adjustable from roughly 0.3 seconds to 5 minutes. Block Time: Fixed at approximately 0.2 seconds after the delay ends.

Sensor Characteristics

The HW416B PIR sensor module has three pins: The HW416B (often interchangeably referred to as the

Mode 1: Single Triggering (Non-repeatable) – Jumper in H position

• Behavior: When motion is detected, the output goes HIGH for the set delay time. Even if the person continues moving during this delay, the timer will NOT reset. The output will turn LOW exactly after the pre-set time, regardless of continued motion.
• When to use: Energy-saving lights, where you want a fixed ON time. Also used in cameras to prevent continuous triggering.

The HW416B PIR sensor datasheet provides a good overview of the sensor's specifications, features, and application information. While there is room for improvement, the datasheet is generally clear and concise, making it easy for users to understand and work with the sensor. With some additional information and examples, the datasheet could be even more helpful for designers and engineers working with the HW416B PIR sensor. Behavior: When motion is detected, the output goes
