 Installation and maintenance of photosynthetically active radiation sensor (PAR sensor)

1. Selection of site

   - The ideal location should ensure that there is no obstacle on the upper end of the sensor element, no obstacle with height angle more than 5° on the sunrise and sunset orientation, and avoid shadows falling on the sensor surface, so as to ensure the accuracy of the measurement data.

2. Installation steps

   - Before installation, please check the product for transportation damage and contact the manufacturer in time.

   - Use two stainless steel screws to firmly fix the photosynthetically active radiation sensor on the bracket, adjust the horizontal position and fasten it.

   - Connect the output wires to the data collector box and start observing the data.

3. Maintenance

   - Check at least once a week to make sure the cosine correction piece is clean, remove deposits such as ice, snow, dust, etc., and keep the sensor surface clean to ensure the measurement accuracy.

   - When using a digital voltmeter to measure, divide the measured voltage value by the sensitivity coefficient of the photosynthetically active radiation sensor to get the radiation amount.
