Overview

Sunshine duration sensor continuously measures daily sunshine hours by recording radiation above a preset threshold. With a 0-24 h range, 0.1 h resolution, and ±2% accuracy, it provides stable outdoor monitoring with low power consumption. Multiple output options, including voltage, 4–20 mA, RS485 Modbus-RTU, and SDI-12, make it suitable for meteorology, agriculture, forestry, environmental monitoring, and research applications.

Feature

Continuous Measurement: Automatically records daily sunshine duration above the preset radiation threshold.
High Accuracy: Sunshine duration sensor uses precision light-sensing components with digital linear correction for stable results.
Real-Sunlight Calibration: Minimizes interference from artificial light and changing environmental conditions.
Reliable Outdoor Use: No moving parts, low power consumption, and strong resistance to vibration.
Easy Installation: Compact, lightweight design for flexible mounting and convenient operation.

FAQ

Q1: What is the difference between a sunshine duration sensor and a pyranometer?

A sunshine duration sensor records the length of time that bright sunshine occurs. A pyranometer measures global solar irradiance, including both direct and diffuse radiation, usually in W/m².

Q2: Does daylight always count as sunshine duration?

No. Weak sunlight around sunrise, sunset or under heavy cloud may be visible but remain below the sunshine threshold, so it is not counted as bright sunshine.

Q3: Does the sensor count sunshine on partly cloudy days?

Yes. It accumulates each period when sunlight exceeds the threshold. When clouds temporarily block the direct solar beam, the accumulation pauses and resumes when sufficient sunlight returns.

sunshine duration sensor works well for weather monitoring

I used this sensor for a small weather station project and it has been working reliably. The sunshine duration sensor was easy to connect to our data collection system, and the readings have been stable after the initial setup. I spent some time checking the installation position to make sure there were no obstacles blocking the sunlight. After that, it has been collecting data without issues.
