Water Cooling Head Water Cooling Plate 40*40mm
[Aluminium Heat Sink] Liquid coolers excel at delivering cooling to concentrated heat sources such as Peltier Elements and for delivering cooled fluid into remote or compact locations where the cooling assembly itself cannot be located. The basic operation is simple: fluid flows in one tube, it is cooled, and then it flows out the other tube. An external pump is required, and typically small DC magnetic-drive pumps are used to minimize the amount of pump power (heat) that is imparted to the fluid. Applications: Computer CPU water, industrial inverter driver, laser head cooling, industrial control cabinet cooling. Features: Heavy Aluminium build Internal flow channel extrusion forming Applicable to computer CPU water, industrial inverter driver, laser head cooling, industrial control cabinet cooling Package Includes: 1 x Water Cooling Head Water Cooling Plate 40*40mm
Out of stockZP4510 P45 Water Level Sensor Float Control Switch
[Water Level Sensor] A float switch is a device used to sense the level of liquid within a tank, it may actuate a pump, an indicator, an alarm, or another device. A float switch is a device used to sense the level of liquid within a tank. The switch may actuate a pump, an indicator, an alarm, or another device. Use them with hydroponics, saltwater tank, freshwater tank, gardening, aquariums for power head control, pet bowls, fish tanks, filtration, heating, pumps, ponds, basement alarms, boats, air condition drain pans, pressure washers, carpet cleaning machine, reef aquarium, fluid control, ice machines, coffee pots, marine, automotive, automobiles, tropical fish tanks, evaporator coils, condensation line, in relays, or whatever your project may be. It can be easily converted from normally open to normally close by inverting the float. Note: because the current that the switch can carry is much little(0.5A), you must use a relay or contactor when it is connected by a load, relay and contactor are not included here. Specifications:- Cable Length: 30.5(cm) Maximum Load: 50 W Max Switching Voltage: 100V DC Minimum Voltage: 250V DC Maximum Switching Current: 0.5 A Max Load Current: 1.0 A Max Contact Resistance: 0.4 ΩTemp Rating: -20~ 80 degree Applications:- Household Equipment such as overhead water tanks, Water purifiers. Use them with hydroponics, saltwater tank, freshwater tank, gardening, aquariums for power head control, pet bowls, fish tanks, filtration, heating, or whatever your project may be. Up float switch Contains no mercury Product. How Magnetic Reed Liquid Level Sensors Work:- The purpose of a float switch is to open or close a circuit as the level of a liquid rises or falls. Most float switches are "normally closed," meaning the two wires coming from the top of the switch complete a circuit when the float is at its low point, resting on its bottom clip or stop (for example, when a tank is dry). Most float switches utilize a magnetic reed switch to open or close the circuit. The reed is encased in a glass tube, which is cemented into a plastic or stainless steel stem with epoxy. The illustration to the left demonstrates how a magnet can be used to open or close a circuit by moving it closer to or farther away from a reed switch. When the magnet comes close to the two contacts, they draw together and touch, allowing the current to pass through. When the magnet is moved away, the contacts demagnetize and separate, breaking the circuit. In a float switch, the magnetic reed switch is hermetically sealed in a stem, most often made from plastic or stainless steel. The float encases a sealed magnet, which moves up and down the length of the stem as a fluid level rises and falls. As the magnet passes by the contacts in the encased reed switch, they draw together and complete a circuit between the two lead wires. The operation shown can usually be reversed by removing the bottom clip from the switch, inverting the float, and replacing the clip. When this change is made, the switch circuit will be open when the float is resting on the bottom clip and closed when the float rises. Properly used, float switches can deliver millions of on/off cycles, for years of dependable operation. Failures are normally due to overloading, frequently caused by spiking voltage. Before designing a circuit that uses a float switch, be sure to read our Technical Page on Spiking Voltage & Float Switches. * Product Images are shown for illustrative purposes only and may differ from the actual products.

The display is 16 character by 2 line display has a very clear and high contrast white text upon a blue background/backlight. This is great blue backlight LCD display. It is fantastic for Arduino based project. This LCD1602 LCD Display is very easy to interface with Arduino or Other Microcontrollers. This display overcomes the drawback of LCD 1602 Parallel LCD Display in which you’ll waste about 8 Pins on your Arduino for the display to get working. Luckily in this product, an I2C adapter is directly soldered right onto the pins of the display. So all you need to connect are the I2C pins, which shows a good library and little of coding. The I2C is a type of serial bus developed by Philips, which uses two bidirectional lines, called SDA (Serial Data Line) and SCL (Serial Clock Line). Both must be connected via pulled-up resistors. The usage voltages are standard as 5V and 3.3V. If you already have the I2C adapter soldered onto the board like in this product, the wiring is quite easy. You should usually have only four pins to hook up. VCC and GND of course. The LCD display works with 5 Volts. So we go for the 5V Pin. The values shown on the display can be either a simple text or numerical values read by the sensors, such as temperature or pressure, or even the number of cycles that the Arduino is performing. Arduino IIC/I2C interface was developed to reduce the IO port usage on Arduino board I2C adapter allows flexibility in connections I2C Reduces the overall wirings. 16 characters wide, 2 rows White text on the Blue background Single LED backlight included can be dimmed easily with a resistor or PWM.
