Product introduction

The blue-green algae digital sensor is an intelligent monitoring blue-green algae digital sensor independently developed by our company. Its principle is to use the characteristic that blue-green algae have absorption peaks and emission peaks in the spectrum, emit monochromatic light at the absorption peak of the blue-green algae spectrum to irradiate the water, and the blue-green algae in the water absorb the energy of monochromatic light, releasing monochromatic light of another wavelength emission peak. The light intensity emitted by the blue-green algae is proportional to the content of blue-green algae in the water. This product is widely used to monitor the concentration of microalgae such as marine harbors, green algae and cyanobacteria such as river and lake reservoirs, and determine the concentration of green algae in the treatment project of green algae cultivation equipment.

main features

◇ This product is a blue-green algae digital sensor, which can directly output RS485 signals.

◇ Without instrument, it can directly connect computer, PLC and other equipment with RS485 signal interface for data acquisition. It is convenient for users to integrate sensors into industrial control environments such as host computer system and IoT system.

◇ Use mobile phone APP to collect, debug and maintain data of sensors through wired (OTG cable and 485 to USB module) or wireless networks (such as WIFI, GPRS and other wireless networks).

◇ The sensor can be set through RS485 communication, such as slave address and baud rate, online calibration, factory restoration, proportional coefficient and incremental compensation.

◇ Two point correction method is adopted.

◇ The core components are from foreign brands.
