TTP223B Capacitive Touch Sensor Module The TTP223B Digital Capacitive Touch Switch Sensor Module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. Allows you to remove the worry of conventional push-type keys. Digital Capacitive Touch Switch Sensor Module is based on TTP223B. Normally, it outputs low and keeps at a low power state. When a touch is sensed on the circular marked region, it outputs high and switches to the quick response state. When not being touched for 12 seconds, it switches to a low-power state again. If the module is mounted on surfaces of non-metallic materials such as plastic, glass, or acrylic, you can make the keys hidden in the walls and desks. In addition to the thin paper ( non-metallic ) covering the surface of the module, as long as the correct location of the touch, you can make it hidden in the walls, desktops and other parts of buttons. Touch Sensor Interface: Control Interface: A total of three pins (GND, VCC, SIG), GND to the ground, VCC is the power supply, SIG digital signal output pin Power Indicator: Green LED, power on the right that is shiny Touch area: Similar to a fingerprint icon inside the area, you can touch the trigger finger. Positioning holes: 4 M2 screws positioning hole diameter is 2.2mm, the positioning of the module is easy to install, to achieve inter-module combination. Applications: Portable devices such as smartphones and tablets (iPhones, iPad, etc.) Home applications such as touch lamps Automotives Industrial

TTP224 - 4 Channel Capacitive Touch Sensor Module 4 Channel Capacitive Touch Sensor Module uses the touch-sensing IC TTP224 to sense the touch input thus making it easy to add capacitive touch input to your project. The touching detection IC is designed for replacing traditional direct button key with diverse pad size. The module has 4 touch pads. Power the module with 2.4 ~ 5.5V DC and the touch pad is all active to sense the input. Four Channel Capacitive Touch Sensor Module is easy to interface. It can be used along with a microcontroller or an Arduino or even without one. When a capacitive load (such as a human hand) is in close proximity to the sense-pad, the sensor detects the change in capacitance and activates the switch. Custom sense-pads can be made from nearly any conductive material and these sensors can detect touch through thin layers of non-conductive materials such as glass, plastic, fabric or even wood. Thus, the 4 Channel Capacitive Touch Sensor Module can be hidden in wall or other places, a perfect alternative to get rid of the conventional push-button troubles. A total of 4 pads are available on this module. The sense-pads can also be extended with a wire or almost any conductive material.

TTP229 16 Channel Capacitive Touch Module This is TTP229 16-Way Capacitive Touch Switch Digital Touch Sensor Keypad Module. This capacitive touch sensor module uses the TTP229 integrated circuit, making it easy to add capacitive touch input to your project. It features 16 sensitive touchpads that make an ideal replacement for the old-fashioned keypads. Capacitive touch allows electronics to sense when your finger is within a few millimeters of a surface to simulate a button “press” just like how the pushbutton works. Capacitive sensing may be used in any place where low to no force human touch sensing is desirable.

LJ12A3-4-Z/BX NPN DC5-36V 4mm Normally Open Tube Type Inductive Proximity Sensor Switch This LJ12A3-4-Z-BX-NPN DC 5-36V Inductive 4mm NPN-NO Proximity Sensor Switch also known as Approach Sensor is a component widely used in the automatic control industry for detecting, controlling, and non-contact switching. When the proximity switch is close to some target object, it will send out a 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. These inductive proximity switches can be non-contact, have no pressure, no spark, and quickly issue the electrical command. Accurately reflect the position and 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, used for precise positioning of molds, precision machine tools, and robots. Applications: It is widely used in machines, paper making, light industry for limiting stations, orientation taking count, speeding trials, etc. Used in the automatic control industry for detecting, controlling, and noncontact switching.

Turbidity Sensor With Module for Liquid Particle Detection A turbidity liquid particle detection sensor is a device that is used to measure the turbidity, or cloudiness, of a liquid. Turbidity is often used as an indication of the presence of suspended particles in the liquid, such as dirt, algae, or bacteria. The sensor works by shining a light through the liquid and measuring the amount of light that is scattered or absorbed by the particle detection. Turbidity is the measurement of particulate matter in water. It requires the analog port of the MCU to read the analog value for calculation. It needs turbidity calibration liquid to calibrate. It is not the multimeter that directly measures the voltage. The output voltage of each module is different. The module should be protected from light and light. The temperature and voltage will make the output voltage of the module different. 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. Parameters of the Turbidity Particle Sensor: Voltage: 3.3-5V (with anti-reverse circuit) Output: default analog (can set high and low output) Measuring range: 0-1000 NTU Key Features: Turbidity can be measured in the range of 0 to 1000 Nephelometric Turbidity Units (NTU). Operates at 3.3-5V and has built-in anti-reverse circuitry for safety. The operating temperature range is from -20°C to 80°C. Uses light scattering or absorption to estimate the presence of suspended particles in liquids. Used in various applications such as water quality monitoring, environmental monitoring, and industrial processes. Turbidity Liquid Particle Detection Sensor Pin Diagram:
