• Dissolved Oxygen Level Sensor for Arduino

Dissolved Oxygen Level Sensor for Arduino by Graylogix is widely used for measuring dissolved oxygen in water. It’s compatible with Arduino, ESP8266, ESP32, STM32 microcontrollers, and Raspberry Pi. Applications include aquaculture, environmental monitoring, and natural science. In a word it serves the purpose of measuring dissolved oxygen in water to reflect water quality.

Calculating Dissolved Oxygen Levels:

Expressed in milligrams per liter (mg/L) or parts per million (ppm), given that dissolved oxygen concentration levels are interchangeable, with 1 mg/L equaling 1 ppm. The Dissolved Oxygen Level Sensor kit includes a signal converter board with a BNC connector, especially directly connectable to the Galvanic Probe. This signal converter board amplifies the minor voltage difference eventually to a readable signal detectable by Arduino. With plug-and-play functionality, coupled with the signal converter board ensures good compatibility.

To protect the sensitive and fragile oxygen-permeable membrane in the membrane cap, for that reason it is crucial to cover the sensor tip. Also Avoid fingernails and other sharp objects to prevent damage. This sensor can seamlessly integrate into any control or likewise detecting system.

Note: lastly a video guide is available for detailed instructions on assembling the DO membrane and filling the membrane cap with KCL solution.

Preparing the Dissolved Oxygen Level Sensor Probe:

For a new dissolved oxygen probe, first thing to remember begin by adding 7.5% KCL solution into the membrane cap as the filling solution. Follow these steps:

Firstly remove the membrane crown.

Secondly place the DO membrane on the cap and fix the crown to the electrolyte tube, covering one side of the membrane.

Also make sure the membrane is free of wrinkles and remains undamaged or punctured

Unscrew the membrane cap from the probe and fill about 2/3 volume of the cap with KCL solution.

Keep the probe in a vertical position concerning the horizontal plane.

Carefully screw the cap back onto the probe. To ensure the probe is fully filled with KCL solution and eliminate air bubbles, we accept some solution overflow

The 7.5% KCL solution acts as a suitable electrolyte in the DO Probe.

The electrode tube should be free of air bubbles to prevent fluctuations in readings.

Check out the data sheet for the calibration process and sample code for Arduino.

            Range 0 to 20.0 ppm

           Resolution 0.1 ppm

CG Electrode Gel is a specially designed conductive gel used during an electrocardiogram (ECG or EKG) procedure. This gel is applied to the electrodes that are placed on the skin to help enhance electrical conductivity between the skin and the electrodes.

Since human skin provides resistance to electrical signals, the gel reduces this resistance, ensuring that the tiny electrical signals produced by the heart are transmitted accurately to the ECG machine. This allows for clearer and more precise readings of the heart’s activity.

Without the ECG Electrode Gel, the quality of the ECG signals might be compromised, leading to less accurate results. It’s non-irritating, safe for use on the skin, and easy to clean off after the procedure.

12V 2CH Relay Module is a small and easy to use . Use it to control one 240V power appliance directly from Arduino, Raspberry Pi, and other microcontrollers or low voltage circuits. Perfect for switching 240V appliances – lights, fans, etc, and even high power motors at lower voltages.

The board uses a high-quality relay, which can handle a maximum of 7A/250 V AC or 10A/125V AC. Each relay has all three connections – Common, Normally Open, Normally Closed brought out to 3 pin screw terminals which make it easy to make and remove connections. The board has a relay status LED to ease debugging. The board can accept control inputs within a wide range of voltages from 4V to 12V.

Relays were first used in long-distance telegraph circuits as signal repeaters they refresh the signal coming in from one circuit by transmitting it on another circuit.Furthermore the telephone exchanges and also the early computers extensively employed relays to perform logical operations

Also electrical relays got their start in application to telegraphs. American scientist Joseph Henry is often cited to have invented a relay in 1835 in order to improve his version of the electrical telegraph, developed earlier in 1831.However, an official patent was not issued until 1840 to Samuel Morse for his telegraph, which is now called a relay.
