This Water Sensor is designed to detect water or liquid leakage. Convenient I2C interface makes it easy to add water leakage detection to any IoT application in seconds. Integrated on-board Buzzer can be used for alarm notification applications. This Water detect Sensor uses a PCA9536 digital IO to detect the water and to control the buzzer.
The water detect lines are connected to the GPIO0, which connects to ground when water is detected (Low: Water Detected, High: No Water Present). The on-board buzzer is activated when IO3 is set high.
PCA9536 has two unused IO pins connected to solder pads, which can be used as general purpose digital IO applications.
This sensor has .75″ square inch of detection area.
All I2C Mini Modules are designed to operate at 5VDC. Using a convenient 4-Pin plug, devices can be daisy chained onto the I2C Bus, eliminating the need for soldering. Simply plug together the devices you need for your next automation application. Pull-up resistors are included with all NCD master devices. If you are wiring in your own I2C port, on-board 4.7K jumper-selectable pull-up resistors are available for convenience purposes.
What is the NCD I2C Interface?
NCD is the creator of plug and play modular hardware using the NCD I2C Interface connector standard. NCD I2C devices allow you to chain together several devices on the I2C bus, and communicate to each device individually at high speed (subject to the limitations of I2C). The NCD I2C Interface uses a standard 4-Pin I2C Input and I2C Output connector. NCD I2C devices communicate 5V I2C data and provides 5V DC power through this connector. NCD I2C devices use standard I2C communications for all data transport, which is supported by nearly every microcontroller in production today. The NCD I2C Interface is strictly a 5V standard, which is ideal for transport across longer cables. NCD I2C devices always include a 6″ (152mm) 4-conductor I2C cable. NCD I2C Mini Modules always include a 3″ (76mm) 4-conductor I2C cable. Cables and connectors are available separately for designers who would like to include their own NCD I2C Interface into their designs.
Plug and Play Connectivity
NCD I2C devices will plug in to any available NCD I2C Output. This includes just about everything we make in the NCD IoT Category, including all NCD IoT devices. We also manufacture a wide range of I2C adapters that make it easy to plug NCD I2C Devices directly into most computing platforms. The NCD I2C Interface adapters are available for Arduino, Banana Pi, BeagleBone, Bluz, C.H.I.P., ESP8266, Onion Omega, Particle Photon and Electron, PyCom, Raspberry Pi, 2, 3, and Zero, and Windows. We are always working to add new platform support for NCD I2C devices. NCD I2C Interface devices are compatible with just about everything in the microcontroller industry.
Unlimited I2C Expansion
Based on our plug-and-play I2C interface standard, all NCD I2C devices are equipped with a I2C output port, making it easy to expand to a wide variety of sensors, current monitors, relay controllers, PWM controllers, and much more! We are always designing new expansions for our modular plug-and-play I2C framework. We are dedicated to building a product line of interconnected devices to simplify all forms of automation. Re-use or upgrade your hardware in seconds by selecting the modules that best fit your needs, and chaining them together using the included I2C expansion cables!
Powering NCD I2C Interface Devices
Some NCD I2C devices require a external power supply, others may be powered through the 4-Pin I2C bus connector at 5VDC, and other devices are jumper selectable between external and I2C bus power. All I2C mini modules are powered through the 5V I2C bus connector, greatly simplifying connectivity.
