Solar radiation sensor Arduino

Solar radiation sensor Arduino product introduction

Solar radiation sensor is a high-precision measuring instrument designed based on the principle of thermoelectric induction, which can accurately measure the total radiation, reflected radiation, scattered radiation, infrared radiation, visible light, ultraviolet radiation, long-wave radiation and other types of radiation from the sun. This product is suitable for solar energy use, meteorology, agriculture, aging of building materials and atmospheric pollution, providing you with reliable solar radiation energy measurement solutions.

 Solar radiation sensor core technology and features.

Core sensing technology:

Multi-Contact Thermopile Design: At the heart of the sensor is a wire-wound electroplated multi-contact thermopile with a highly absorbent black coating to ensure maximum radiation absorption.

Differential Potential Principle: The hot junction is directly exposed to solar radiation, while the cold junction is deep inside, the temperature difference between the two produces a stable potential difference, which is converted into an electrical signal for accurate quantification of the radiation.

Double glass cover design:

Reduces air convection interference: The double-layer structure effectively isolates the sensor from external environmental influences, and the inner layer is designed to prevent interference from the outer shell's own radiation, ensuring the purity of the measurement.

Solar radiation senso is versatile:

Comprehensive radiation measurement: from total radiation to scattered, reflected and even specific bands of radiation, it is widely used in solar panel efficiency assessment, climate change research, crop growth monitoring and so on.

Flexible mounting: horizontal, tilted or at a specific angle, it can capture radiation data accurately, and with the addition of a shading ring, it can accurately measure scattered radiation.

 Solar radiation sensor technical parameters

Solar radiation senso technical parameters highlights:

1. High sensitivity: 7 ~ 14μV / W-m ², to ensure that even small radiation changes can be accurately captured.

2. Wide measurement range: 0-2000W/m², covering the radiation measurement needs in daily and extreme conditions.

3. Multiple output forms: support DC 5V/12V/24V power supply, as well as current and voltage output, RS485 communication interface, easy to integrate with modern data acquisition systems, such as the Arduino platform, through simple programming to achieve real-time data transmission and processing.

4. Excellent stability: annual stability of ≤ ± 2%, to ensure the accuracy of long-term monitoring.

5. Adapt to harsh environments: Operating temperature range -40℃ to +50℃, fearless of extreme climate challenges.

Solar radiation sensor Arduino connection steps

1. Power supply connection:

   - Connect the VCC and GND pins of the RS485 converter module to the 5V and GND pins of the Arduino respectively.

2. RS485 signal line connection:

   - Connect the A (non-inverted) and B (inverted) wires of the solar radiation sensor to the corresponding terminals of the RS485 converter module.

3. Converter module and Arduino connection:

   - Connect TXD of the RS485 conversion module to digital pin 10 (RX) and RXD to digital pin 11 (TX) of the Arduino.

4. Programming:

   - Use the Arduino IDE to write a programme to configure the serial communication parameters, read and parse the sensor data.

 Solar radiation sensor connected to Arduino sample code:

include <SoftwareSerial.h

// Define the Arduino pins that connect to the RS485 module.

const int rs485RxPin = 10; // RX

const int rs485TxPin = 11; // TX

SoftwareSerial rs485Serial(rs485RxPin, rs485TxPin); // create the soft serial object

void setup() {

  Serial.begin(9600); // initialise serial communication for debugging purposes

  rs485Serial.begin(9600); // RS485 baud rate, match sensor settings.

}

void loop() {

  if (rs485Serial.available()) {

    String data = rs485Serial.readStringUntil(‘ ’); // Read RS485 sensor data.

    Serial.println(data); // process and display the data

  }

}

Debugging and testing: Upload the code to Arduino, start the programme and observe whether the data output is as expected. Adjust the sensor position or parameter settings as needed to get the best measurement results.
