The CW1300-1 from Comus is a nonmercury tilt sensor. These operate when tilted from the horizontal position. The switch movement required to cause contact change is called the differential angle. It is very important when designing a tilt switch to allow the differential angle and understand that when in the horizontal position the switch contact may be open or closed.

Features:

1. Resistant to Ambient Environmental Conditions
2. Case Material Tin Plated
3.  Hermetically Sealed & Inert Gas Filled
4.  Customization Available

Specifications:

1. Contact Capacity: 60 V MAX, 0.25 A MAX, 3 VA MAX
2. Contact Resistance: 30 Ω MAX Measured 10° Below Horizontal at 5 VDC
3. Make Angle: 10° MAX Below Horizontal
4. Break Angle: 10° MAX Above Horizontal
5. Differential Angle: 15° MAX
6. Operating Temperature: -37° to 100°C

Package Includes:

1 x COMUS Tilt Switch, 15 °, 60 Vac, 0.25 A, Nickel

Magic Light Cup Module is a board which has a led and a mercury tilt switch. Using PWM to drive the LEDs on the module you can achieve the effect of light being “magically” transferred from one module to the other when tilting them. In short, it’s 2 components combined, a mercury tilt switch and a led. On tilting the module mercury inside small tube connect the switching point and make switch ON while tilting it to other side move the mercury and it disconnects the circuit and switch get OFF. The module operates on 5V DC supply.

So the magic in the name of this module is because when you tilt the switch, the led will turn on and off. And Of course, it is also possible to connect it to the NodeMCU.

This Tube Type Inductive Proximity Sensor Detection Switch NPN DC6-36V 4mm Normally Open switch LJ12A3-4-Z/BX is a component widely used in automatic control industry for detecting, controlling, and non-contact switching. When the proximity switch is close to some target object, it will send out control signal.

When the metal approaches near-proximity switch sensing area, an Edy Current is induced in metal. Which in turn disturbs the magnetic field produced by the Inductive Proximity Sensor. This change is sensed by the sensor.

This inductive proximity switches can be non-contact, no pressure, no spark, quickly issued the electrical command. Accurately reflect the position and the stroke movement mechanism. Positioning accuracy, operating frequency, service life. Easy to install and suitable for harsh environments.

This 4mm proximity sensor can detect a variety of metals, miniature size, long life, low price, shielded type installation, anti-interference ability, 1mm detection distance, using for precise positioning of molds, precision machine tools, and robots.

Product Details:

Water flow sensor can be used to measure the flow of liquids, i.e. the consumption of liquids in industrial or domestic usage. For example you can make a robotic cocktail dispensing machine, and can use this sensors to accurately measure components like Soda, Water, etc. Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse Signal.

Connection details:

• Red wire is 5V
• Black wire is GND
• White wire is PWM signal output

Description:

• Lowest rated working voltage: DC4.5 5V-24V
• Operating humidity range: 35%~90%RH (no frost)
• Allowed pressure: pressure 1.75Mpa
• External threads: 1/2"

Product Details:

Features:

• Electrical and mechanical interlocks prevent cross connection of power sources.
• Quick change circuit board is easily replaced in the event of failure. No need to disconnect and reinstall the entire unit.
• Time delay ensures generator voltage is at a stable level before transfer occurs. The time delay can be disabled when an inverter is used as the alternate source.
