This DN32 water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, the rotor rolls. Its speed changes with different rates of flow. The hall-effect sensor outputs the corresponding pulse signal. This one is suitable to detect flow in water dispensers or coffee machines.

We have a comprehensive range of water flow sensors in different diameters. Check them out to find the one that meets your need most.

A cable Float Switch is a control device for automatic On/Off pumps, motors,s and magnetic valves. It is also an alarm device at certain pre-determined surface levels. It is suitable for use in non-flammable liquids at 250 volts. In potentially explosive atmospheres (e.g. oil tanks) the Switch can be used in conjunction with (Ex) I-isolator switch units. Due to its large float casing, the float Switch has a buoyancy that guarantees smooth, trouble-free operation under all conditions. The switch has a double chamber and a final remolding finish to make it absolutely hermetic.

Features: 

1. It can test the pressure of the liquid
2. The float switch is a switch that regulates fluid level in the tank or well etc
3. The float switch is resistant to water(sewage water) it is relatively capable of being used for oil, most acids and alkalis
4. The float switch is not explosion-proof

Package Includes:

1 x Square 3 M Float Switch For Industry Pump Tank Sensor

This is a sensor that detects chlorine concentration and supports three output modes: analog, I2C, and UART. The probe has been calibrated at the factory, which can quickly and accurately measure the concentration of chlorine in the environment. Can be widely used in the detection of chlorine in the chemical, pharmaceutical production, and environmental protection fields.

The probe adopts the electrochemical principle, has the characteristics of strong anti-interference ability, high stability, high sensitivity, etc., and the service life is as long as two years. The sensor has 32 modifiable I2C addresses, an integrated temperature compensation algorithm, and a threshold alarm function, It has good compatibility with mainstream main control devices such as Arduino, esp32, and raspberry pi. The easy-to-use Gravity interface, coupled with our sample code, can quickly build a chlorine concentration detector.

Gravity: Analog TDS Sensor/Meter for Arduino is an Arduino-compatible TDS Meter Kit for measuring TDS value of the water, to reflect the cleanliness of the water. TDS meter can be applied to domestic water, hydroponic and other fields of water quality testing. You may also check Liquid Senser Selection Guide to get better familiar with our liquid sensor series.

TDS (Total Dissolved Solids) indicates that how many milligrams of soluble solids dissolved in one liter of water. In general, the higher the TDS value, the more soluble solids dissolved in water, and the less clean the water is. Therefore, the TDS value can be used as one of the references for reflecting the cleanliness of water.

TDS pen is widely used equipment to measure TDS value. The price is affordable, and it is easy to use, but it is not able to transmit data to the control system for online monitoring to do some water quality analysis. The professional instrument has high accuracy and can send data to the control system, but the price is expensive for ordinary people. To this end, we have launched an analog TDS sensor kit that is compatible with Arduino, plug, and play, easy to use. Matching with Arduino controller, you can build a TDS detector easily to measure the TDS value of liquid.
This tds sensor supports 3.3 ~ 5.5V wide voltage input, and 0 ~ 2.3V analog voltage output, which makes it compatible with a 5V or 3.3V control system or board. The excitation source is an AC signal, which can effectively prevent the probe from polarization and prolong the life of the probe, meanwhile, increase the stability of the output signal. The TDS probe is waterproof, it can be immersed in water for a long time measurement.
