Water Flow & Rain-Drop Sensor

Now easily measure water (liquid) flow in your application using this 1/2″ Brass water flow sensor. This is good quality flow sensor with brass body and can be used for industrial and commercial applications. This half inch water flow sensor is used extensively is various types of vending machines.

This water flow sensor is connected in line with the liquid whose flow rate has to be measured. There is a simple rotating wheel with a magnet and when the liquid flows the wheel is rotated and a hall effect sensor measures how many times he wheel is rotated and accordingly gives pulses. By counting the number of pulses you can easily calculate the flow rate as well as the amount of liquid dispensed.

The sensor comes with a 3 pin JST connector.

Red : Vcc 5 to 18 volts

Black :  Ground

Yellow : Pulse Output signal

This is a Turbidity Sensor with Module, an electronic monitoring module specially developed to work with microcontroller platforms Arduino, Raspberry Pi, PIC, ARM, AVR, among others.

It is very efficient, the Arduino Turbidity Sensor is able to detect and verify the quality of the water, making the turbidity measurement, where it is possible to verify the results by means of digital or analog signal next to the corresponding pins in the accompanying electronic module.

The Turbidity Sensor emits at its end an infrared light, imperceptible to human vision, capable of detecting particles that are suspended in water, measuring the light transmittance and the dispersion rate, which changes according to the Amount of TSS (Total Suspended Solids), increasing the turbidity of the liquid whenever levels increase.

In general, the Arduino Turbidity Sensor is applied in projects involving the monitoring of water turbidity in rivers, streams, lakes, water bodies, catchment and research sites, laboratories, tanks with liquids and so on. This Turbidity Sensor has an end specially prepared for direct contact, having an electronic module to amplify and send the received data to the microcontroller of the project

Theory of Operation

The sensor operates on the principle that when the light is passed through a sample of water, the amount of light transmitted through the sample is dependent on the amount of soil in the water. As the soil level increases, the amount of transmitted light decreases. The turbidity sensor measures the amount of transmitted light to determine the turbidity of the wash water. These turbidity measurements are sent to the dishwasher controller, which makes decisions on how long to wash in all the cycles.

These decisions are made on the basis of a comparison between clean water measurements (taken at the beginning of the wash cycle) and the wash water turbidity measurement taken at the end of each wash cycle. By measuring the turbidity of the wash water, the dishwasher can conserve energy on lightly soiled loads by only washing as long as necessary. This will result in energy savings for the consumer.

A float switch is a type of level sensor, a device used to detect the level of liquid within a tank. It is a simple structure, easy to use level control device; moreover, it is neither a complicated circuit nor does it provide power. This switch has a mechanical switch than the average small sized switches.

As long as the material used is in the correct shape and nature of any liquid or pressure, you can control the temperature. Applications of this Switch include shipbuilding industry, generating equipment, petrochemical and food industry, water treatment equipment, dyeing, and finishing industry, and hydraulic machinery.
