Water Flow & Rain-Drop Sensor

This water level sensor module has a series of parallel exposed traces to measure droplets/water volume in order to determine the water level. Very Easy to monitor water level as the output to analog signal is directly proportional to the water level. This output analog values can be directly read via ADC and can also be connected directly Arduino’s analog input pins.

A float sensor or a float switch is a sensor used to detect the level of liquid (water) in a tank. Normally the purpose of a float switch is to open or close a circuit as the level of a liquid rises or falls.

Our float sensor has a magnet on the float (the moving part) and a reed switch on the stem (fixed part). So when the magnet comes near the reed switch the reed switch is activated and the circuit becomes closed.

R385 6-12V DC Diaphragm Based Mini Aquarium Water Pump is an ideal non submersible pump for variety of liquid movement application. It has enough pressure to be used with nozzle to make spray system. The pump can handle heated liquids up to a temperature of 80°C and when suitably powered can suck water through the tube from up to 2m and pump water vertically for up to 3m.

Possible uses/projects include; a small aquarium pump, automatic plant watering system, making a water feature or music activated dancing water features to name but a few. When pumping a liquid the pump runs very quietly. The pump is also capable of pumping air, though when pumping air the pump is quite noisy in comparison.

The R385 requires between 6 – 12V DC and between 0.5 – 0.7A and will deliver its maximum operating values when power is at the upper end of these ranges.

This immersible pump can be used to water your plants, make a fountain or waterfall, and even change your fish tank water. It works quietly with the sound level under 30db. The pump has a filter inside as well as a suction cup which can help stick it to smooth surfaces tightly.

To prevent from COVID-19, hand sanitization is must. However, dispensing through bottle requires manual operation by hand. Let’s avoid and go touchless with Automatic Hand Sanitizer, that will ensure that you maintain proper hygiene and heath in public spaces. Ideal for Factories, Offices, Hospitals, Malls, Railways, Shops, and Homes.

YF-DN50 is a large 2 inch diameter Water Flow meter Sensor that can be used to measure flow rate from 10 – 200 Liter/min.

1/8 inch Water flow sensor YF-S401 consists of a plastic valve body, a water rotor, and a hall effect sensor – when water flows through, the internal rotator will change its speed with different rate of flow and hall effect sensor outputs the corresponding pulse signal. Use with laser cutters or CNC to measure if and how much water is flowing through laser tube or CNC spindle for cooling.

Use this flow sensor to measure the rate to flow of liquids. The sensor has a digital interface which makes it simple and easy to connect it to a microcontroller, Arduino or a Raspberry Pi. It requires no extra circuit to start measuring liquid flow rate. The sensor will have to be attached in the liquid line whose flow is to be measured. A pinwheel inside the sensor moves as the liquid flows through the sensor. A hall effect sensor within the sensor senses the rotation of the pinwheel and outputs a digital pulse for every rotation. By counting the pulses from the sensor, you can easily sense liquid flow through the sensor. This allows easy interface to microcontroller, Arduino, Raspberry Pi, etc.

The sensor comes with three wires – Red (5V-12V), Black (Ground) and Yellow (Output pulse)

This sensor is great for water testing, water cooling systems, measure liquid flow, etc.

Accurate flow measurement is an essential step both in the terms of qualitative and economic points of view. Flow meters have proven excellent devices for measuring water flow, and now it is very easy to build a water management system using the renowned water flow sensor YF-S201.  For example you can make a robotic cocktail dispensing machine, and can use this sensors to accurately measure components like Soda, Water, etc.

YF-S201 1/2 inch Water Flow Sensor sits in line with the water line and contains a pinwheel sensor to measure how much water has moved through it. There is an integrated magnetic Hall-Effect sensor that outputs an electrical pulse with every revolution. YF-S201 1/2 inch water flow sensor has only three wires and it can be easily interfaced between any microcontroller and Arduino board. It requires only +5V Vcc and gives pulse output, the sensor needs to be tightly fitted between water pipeline.
