Water Level sensor  have a  series of parallel wire exposed traces that helps to detect the  water level , rain , water leak. The sensor traces have a weal pull up resistor of 1 MΩ. It is easy to use with better performance with Arduino 328 controller and sensor relay shield.

The Gy-50 Angular velocity Sensor is a sensor module that has a full scale of ±250/±500/±2000 dps. It is capable of measuring rates according to the user’s bandwidth selection. The applicable fields for this sensor module are gaming, 3D motion control, Virtual reality input devices, Robotics, UAV, IMU systems and many more.

The LGZD Sensor Module is a Turbidity Sensor for Water Monitoring module. It has features of monitoring of water turbidity in rivers, streams, lakes, water boxes, catchment and research sites, laboratories, tanks with liquids and etc. It is Compatible with Arduino, Raspberry Pi, AVR, PIC, etc

The Float Sensor Blue is a plastic made device which is used to detect the level of liquid in a tank. It can be used in a pump, an indicator, an alarm or other devices. It can be suitable various applications like: - hydroponics, saltwater tank, freshwater tank, gardening, aquariums for head control, pet bowls, filtration, heating and so on. It is also useful in various projects that contains no mercury.

The Float Sensor Black is a plastic made device which is used to detect the level of liquid in a tank. It can be used in a pump, an indicator, an alarm or other devices. It can be suitable various applications like: - hydroponics, saltwater tank, freshwater tank, gardening, aquariums for head control, pet bowls, filtration, heating and so on. It is also useful in various projects that contains no mercury.

It can sensor and regulate the water level in barrels, sinks, or well. Nontoxic type can be used in house or factory. As the level of liquid reaches a high or lower switching value, the controller contacts will send the signals. It will calculate the flow of water. This electronic device contains a pinwheel sensor connected with a magnetic hall effect sensor. This device is used in various sectors like a water heater, water machine, card machine, various types of filling equipment and water control devices, and many more.

The Soil Moisture Sensor is equipped potentiometer and soil moisture thresholds. It determine the moisture of the soil and helps in automatically water garden under soil humidity control.it has digital switching indicator LED. It can also prevent contact with the soil from rust problems.

Water flow sensor YF-S201 calculate the flow of water  . It contains pinwheel sensor integrated with magnetic Hall Effect sensor.  The hall effect sensor is sealed from  the water pipe to keep it safe and dry which  outputs an electrical pulses with every revolution. It consist of a plastic valve body  It is mainly used for water heater , water machine , card machine , various types of  filling equipment’s and water control device and many more.

It is a useful device for homes, hospitals, industries, etc. This product  basically saves water, electricity and time and helps in preventing the overflow of water from the overhead tank, enabling users  to efficiently manage their water resource and prevent any wastage.
