LoRaWAN-Enabled Dissolved Oxygen (DO) Sensor

The IoT sensing terminal designed specifically for remote water quality monitoring empowers aquaculture, environmental supervision, and industrial water treatment scenarios through real-time tracking of dissolved oxygen (DO) concentration. Integrated LoRaWAN low-power wide area communication technology enables 10km+ultra long distance data transmission, paired with IP68 waterproof casing and anti biological pollution electrodes, ensuring long-term reliable operation in harsh underwater environments.

รายละเอียดสินค้า

LoRa water quality dissolved oxygen sensor is a device used to measure the amount of dissolved oxygen in water. 

Dissolved Oxygen Sensor Features:

  • The DO sensor measures DO with a fluorimetric method that does not consume oxygen and does not use electrolytes.

  • Temperature-compensated transmitter is installed inside, which can automatically adjust the result of a measurement according to the water temperature to ensure the accuracy of the data.

  • Imported fluorescent film is used, the quality is good, and the measured data is stable and reliable.

  • The LoRaWAN collector and water quality dissolved oxygen transmitter are connected with aviation connectors, which are convenient and fast to install and disassemble.

  • It is based on LoRaTM spread spectrum modulation technology, and the signal can be transmitted far, so there is no need to worry about distance.

  • It can be very useful in water treatment, aquaculture, environmental monitoring and other industries.

Product Applications

1. Aquaculture: Real time monitoring of oxygen content in water.

2. Sewage treatment: promote water purification. Ensure the activity of microorganisms and improve the efficiency of sewage treatment.

3. Environmental protection: Helps evaluate water quality and take corresponding protective measures.

4. Natural water monitoring: It is of great significance for maintaining the ecological balance of water bodies and protecting aquatic organisms.

DO Transmitter Size and Installation

1. Submerged installation: The lead wire of the equipment is passed through the waterproof pipe, and the 3/4 thread on the top of the equipment is connected with the 3/4 thread of the waterproof pipe with raw material tape. Make sure that the top of the equipment and the equipment lines are free of water.

2. Pipe Installation: Connect to the pipe through the 3/4 thread of the device.
