DC 7V-24V Sound Light Sensor Relay with 3-60s Delay – GODIYMODULES

Description

Product Overview

The DC 7V-24V Sound Light Sensor Relay from GODIYMODULES is a compact, versatile module designed for both industrial and hobbyist applications. Constructed from high‑impact plastic, the unit measures 1.96″ × 1.29″ × 0.71″ and weighs only 0.09 lb, making it easy to integrate into tight spaces. It features a dual‑mode detection system that can respond to acoustic signals, ambient light, or a combination of both, providing flexible control for a wide range of projects. The built‑in two‑stage amplification circuit boosts sound input from roughly 10 dB up to 90 dB, while the light sensor offers an adjustable range from 10 LX to 10,000 LX, covering conditions from a dark room to bright midday sunlight. Users can set a delay interval anywhere between 3 and 60 seconds, allowing for timed activation of downstream devices such as relays, LEDs, or buzzers. Reverse polarity protection safeguards the module against incorrect power connections, ensuring long‑term durability. The product is identified by model JY-3-60s-001 and carries the GODIYMODULES brand, reflecting a commitment to quality and reliable performance.

Usage

This sensor relay excels in environments where automated response to sound or light is required. In smart home installations, it can trigger lighting or alarms when a doorbell rings or when ambient light drops below a preset threshold, creating energy‑saving illumination schedules. In industrial settings, the module can monitor machinery noise levels and activate safety indicators if sound exceeds a defined limit, helping to prevent equipment damage. Hobbyists building robotics projects often use the adjustable delay to synchronize motor actions with auditory cues, while makers developing interactive art installations rely on the light sensitivity to create dynamic visual effects that react to changing illumination. The module’s compact size and low power consumption make it suitable for battery‑powered devices, and its robust plastic housing ensures resistance to dust and minor impacts, extending its usefulness across outdoor garden lighting, greenhouse monitoring, and classroom experiments.

FAQ

Can the module operate on both 7V and 24V power supplies?

Yes, the relay is designed to accept a wide input voltage range from 7 V up to 24 V, allowing it to be powered by common battery packs, USB regulators, or standard DC power adapters without additional conversion circuitry.

How do I set the delay time to a specific value?

The delay is adjusted using the built‑in potentiometer labeled “Delay” on the module. Turning the knob clockwise shortens the delay toward 3 seconds, while counter‑clockwise rotation extends it up to 60 seconds. A simple multimeter can be used to verify the exact timing if precise calibration is required.

Is the sensor safe to use in humid or dusty environments?

The housing is made from high‑impact plastic with sealed openings for the sound and light sensors, providing a degree of protection against moisture and dust. While it is not rated for complete waterproofing, it performs reliably in typical workshop, greenhouse, or indoor automation settings where occasional splashes or dust exposure occur.

What happens if I connect the power supply backwards?

Thanks to the built‑in reverse polarity protection circuit, the module will simply refuse to power on when the supply leads are reversed. No damage occurs to the internal components, and the device will resume normal operation once the correct polarity is restored.

Can I use the module with other microcontroller platforms?

Absolutely. The relay’s control pins operate at standard logic levels, making it compatible with Arduino, Raspberry Pi, ESP32, and many other microcontroller families. You can program the microcontroller to read the sensor output or to drive the relay directly, enabling complex automation sequences and remote monitoring.
