Hw-416-b

: Serving as the primary motion detector in DIY intruder alarms.

Features dual onboard potentiometers to manually adjust sensitivity (distance) and delay duration (up to 300 seconds).

: The output goes low immediately after the delay time ends, even if motion continues. hw-416-b

The HW-416-B is a dedicated electronic ignition module designed to restore reliable spark ignition to 4-burner gas grills. This component serves as the central control hub for the grill's ignition system, receiving the signal from the push-button switch and distributing the electrical spark to the individual electrode wires. It is constructed with heat-resistant materials to withstand the high-temperature environment of a grill firebox.

: Turning it clockwise increases the duration the output signal stays "High" after motion stops. PIR Motion Sensor HW416B - Tayda Electronics : Serving as the primary motion detector in

Includes dedicated ports for adding a photoresistor (for day/night switching) or a thermistor (for temperature compensation). Pros and Cons Pros Cons

If this is the item you are referring to, here is a standard descriptive text suitable for a product listing or catalog: The HW-416-B is a dedicated electronic ignition module

: The delay timer resets with every detected motion, keeping the output high as long as someone is moving within range.

Includes an EMC-certified layout and low-noise amplifier to reduce false triggers from temperature fluctuations or light changes.

The is a popular, low-cost PIR (Passive Infrared) Motion Sensor module widely used in DIY electronics and IoT projects . It is often sold as a functionally equivalent or improved version of the standard HC-SR501 sensor. Key Features & Performance
