2.1 Product Information
The blue-green algae sensor utilizes the characteristic that the cyanobacteria has an absorption peak and an emission peak in the spectrum. The spectral absorption peak of the cyanobacteria emits monochromatic light to the water, and the cyanobacteria in the water absorbs the energy of the monochromatic light, releasing another wavelength. With monochromatic light emitting peaks, the intensity of light emitted by cyanobacteria is proportional to the amount of cyanobacteria in water. The sensor is easy to install and use. Widely used in monitoring of blue-green algae in water stations, surface water, etc. The sensor is shown in Figure 1.

3.1 Installation of Sensors
The specific installation steps are as follows:
a. Install the 8 (mounting plate) on the railing by the pool with 1 (M8 U-shape clamp) at the sensor mounting position;
b. Connect 9 (adapter) to 2 (DN32) PVC pipe by glue, pass the sensor cable through PVC pipe until the sensor screws into 9 (adapter), and do waterproof treatment;
c. Fix 2 (DN32 tube) onto 8 (mounting plate) by 4 (DN42U-shape clamp).
