Description
The industrial-grade total solar radiation sensor monitors solar radiation from 300 to 1100 nanometers. Generates a current signal proportional to incident radiation intensity when exposed to illuminating radiation, with sensitivity directly proportional to the cosine of the angle of incidence. The range is 0 to 2000 W/m². Supports MODBUS-RTU RS485 protocol, connecting to RS485 data logger for tailored monitoring.
Rated IP68, this robust total solar radiation sensor operates from -30°C to 75°C, thriving in harsh outdoor conditions. It ensures precise solar radiation measurements, optimizing agricultural management for improved crop yield and quality. It also aids researchers in better utilizing solar energy by enhancing their understanding of radiation.
Application

- Weather Monitoring: Measures solar, ground, and atmospheric radiation, aiding weather forecasting and research.
- Agricultural Study: Explores agricultural meteorology, crop growth, and ecology.
- Environmental Monitoring: Tracks radiation levels to assess environmental impact.
- Energy Research: Supports solar and other energy studies by analyzing radiation conditions.
Measuring total solar radiation is crucial in multiple fields, providing essential data for weather prediction, climate study, solar energy utilization, agriculture, and environmental research. It directly impacts climate trends, solar panel efficiency, crop growth, and energy project feasibility.
For instance, in agriculture, plants respond uniquely to solar radiation, making accurate measurements invaluable for optimizing irrigation, fertilization, and planting strategies based on photosynthesis and lighting needs.

Warranty, shipping, and purchasing information
- All prices are stated in US dollars (USD), unless otherwise indicated.
- Full payment must be received and confirmed before an order is prepared or dispatched.
- Payment may be made by bank transfer, Bitcoin, or USDT. The payment methods available for each order are displayed at checkout.
- Shipping charges are shown separately at checkout. The quoted shipping charge includes applicable import duties, taxes, and customs-clearance charges for the delivery destination.
- An electronic invoice is made available in the Customer’s account after payment confirmation. An official sales invoice also accompanies the shipment.
- Orders may be cancelled for a full refund before order preparation begins. Once preparation has begun, cancellation is subject to the order’s processing status.
- A Customer wishing to return a non-defective product must request the return within 30 days of delivery. The product must be returned in good condition with its official sales invoice.
- For a non-defective return, the Customer is responsible for return shipping. The refund covers the product price only; the original shipping charge is not refundable.
- Refunds for returned products are initiated after the returned goods have been received and their condition verified. Approved refunds are initiated within seven business days and returned through the original payment method.
- The refundable amount is based on the USD value paid for the product. Refunds for Bitcoin or USDT payments are calculated against that USD amount, rather than a fixed quantity of cryptocurrency.
