Reviews Capacitive Proximity Sensor

uxcell a11021800ux0169 SN04-N DC 10-30V 200mA NPN NO 3-Wire 4mm Approach Sensor Inductive Proximity Switch

5MM LONG DETECTION DISTANCE: This is a professional normally close proximity switch sensor with 5mm detection distance. Detection object: magnetic metal (detection distance is reduced when non-magnetic metal).
GOOD DETECTION SWITCH: When proximity switch is close to some target object, it will send out control signal..
AUTOMATIC CONTROL COMPONENT: It is a component widely used in automatic control industry for detecting, controlling, and non-contact switching..
OUTSTANDING PERFORMANCE: The approach sensor has the advantages of high sensitivity, quick response, stable performance..
NON-CONTACT DETECTION: Non-contact detection avoids the sensor and the target object from damages..

This capacitive soil moisture sensor is distinguished from most resistive sensors on the market and uses capacitive sensing to detect soil moisture. The problem that the resistance sensor is easily corroded is avoided, and its working life is greatly extended..
The sensor has a built-in voltage regulator chip that supports a 3.3-5.5V working environment, which means it works even on a 3.3-5.5V Arduino control board. A miniature PC such as the Raspberry Pi only needs an external ADC (analog to digital signal) conversion module to work..
With an external screen and a motherboard, you can talk to your plants! See if it is thirsty and you don't need more water to moisten.Garden plants, Moisture detection, Intelligent agriculture.

NEW BIG Candy Corn proximity sensor switch is just as great as the LITTLE Candy Corn proximity sensor switch, but almost twice the size and with new features! BIG Candy Corn is highly sensitive and does not require a physical touch from the user to activate. Simply wave a hand or move your body within 1-in/2.5-cm of BIG Candy Corn and it activates..
Auditory beep and visual feedback can be turned on and off.
Larger activation area that is approximately 3.5-in/9-cm wide (80% wider than the LITTLE Candy Corn!).
Easier to activate – activates when the user is within 1-in/2.5-cm of the switch top or with a light touch.

Zurn’s Aqua-FIT Serio Series Single Post Sensor Faucet combines high functionality and customization with simple installation. Its chrome-plated heavy-duty cast brass body holds up in high-use commercial environments. The battery-powered Z6950-XL-S-E is a single hole, deck-installation with a concealed, downward-facing sensor to help prevent tampering and increase durability. Its convergence-type infrared proximity sensor is accurate and efficient, while the faucet’s 1.5 gpm aerator and 30-second timeout feature boost water and cost savings. The Aqua-FIT Serio Series offers a quick and easy solution for upgrading any commercial retrofit project..
Water-efficient and vandal-proof 1.5 gpm aerator with 30-second timeout feature saves water and money.
Vandal-resistant flow control options include: 1.5 and 1.0 gpm aerated, 0.5 and 0.35 gpm non-aerated, and 1.5, 1.0, and 0.5 gpm laminar flow.
Battery-powered faucet uses 4 standard AA batteries - hardwired, plug-in, or 10-year long-life battery power options are available for continued, worry-free operation.
Concealed, downward-facing proximity sensor deters vandalism and improves performance.

The newly redesigned 1000 Watt motor now costs even less to operate.
Even better for the environment than the previous V Series (AB12)..
The Dyson is a touch free operation with a proximity capacitive sensors..
The Dyson hand dryer saves you money. It costs up to 80.3% less to run than standard hand dryers and up to 97.9% less than paper towels..

It is a component widely used in automatic control industry for detecting, controlling, and noncontact switching..
it can be applied for 3D printer auto leveling, When proximity switch is close to some target object, it will send out control signal..
As it is capacitive type proximity switch, its detecting object target is not limited to only conductor, but also liquid and even powder things, like plastic, water, glass, oil, etc..
It's widely used in machine, paper making, light industry for limiting station, orientation taking count, speeding trial ect..
