Daylight Sensor (16A, IP65, Pole Mount) – Model ESY-LD01 | Automatic Day Night On Off Switch Dust Dawn

Upgrade Your Outdoor Lighting System

The ESY-LD01 Daylight Sensor is an intelligent and energy-efficient lighting control solution that automatically operates lights based on ambient light levels.
Whether you manage street lighting, garden fixtures, perimeter security, or commercial outdoor systems, this sensor ensures hassle-free illumination from dusk to dawn.

Built for reliability, energy savings, and long life, the ESY-LD01 reduces manual intervention and enhances lighting efficiency in any environment.

What is a Daylight Sensor?

A daylight sensor (also known as a day-night sensor or photocell sensor) automatically switches lights ON or OFF based on natural light intensity.
When ambient light falls below a preset threshold (like at dusk), the lights turn ON automatically — and turn OFF when daylight returns.

This makes the ESY-LD01 16A sensor ideal for:

• Outdoor lighting automation

• Industrial zones

• Street and municipal lighting

• Security and perimeter lighting

Key Features

1. Automatic Light Detection (5–50 Lux)

• Accurately senses ambient light levels within a 5–50 Lux range.

• Prevents false switching during cloudy or partially lit conditions.

2. High Load Capacity (16A Rated)

• Supports multiple or high-wattage lighting fixtures without external relays.

• Suitable for heavy-duty street or industrial lighting systems.

3. Wide Operating Voltage (220–270V AC)

• Compatible with standard Indian electrical systems.

• Ensures stable operation under voltage fluctuations.

4. IP65 Weatherproof Protection

• Designed for rugged outdoor use.

• Resistant to dust, rain, and environmental stress for long service life.

5. Temperature & Humidity Tolerance

• Operating Temperature: -10°C to +70°C

• Relative Humidity: < 93% RH

• Performs reliably in diverse Indian climates.

6. Easy Pole Mount Design

• Convenient pole or wall mounting using pre-cut holes.

• Quick to install and service.

7. Compact Size

• Dimensions: 70mm (L) × 55mm (B) × 140mm (H)

• Minimal visual footprint with maximum functionality.

Applications

Ideal for a wide range of outdoor and industrial setups:

• Street Lighting Automation

• Residential Society & Compound Lights

• Garden and Landscape Lighting

• Parking Lot Illumination

• Perimeter & Security Lighting

• Industrial Campus & Factory Exterior Lights

• Government & Smart City Projects

• Warehouse & Logistics Facilities

Benefits of Using a Daylight Sensor

• Energy Efficiency: Operates lights only when necessary.

• Reduced Maintenance: No manual switching required.

• Cost Savings: Cuts down on electricity bills and extends light lifespan.

• Eco-Friendly: Supports sustainability and reduces carbon footprint.

• Enhanced Security: Ensures well-lit surroundings during night hours.

Installation Guide

1. Mount the sensor on a pole or wall facing open sky/light.

2. Ensure the translucent top is not shaded or obstructed.

3. Connect Live (L), Neutral (N), and Load (OUT) wires as labeled.

4. Test by covering/uncovering the sensor to simulate day/night operation.

Note: Avoid installation under trees, eaves, or shaded areas to maintain Lux detection accuracy.
