Featured Product Kit
Water Leak Detection Kit using the PI-SPI series of products. Water damage is one of the leading insurance claims in North America.
Using a Raspberry Pi and the PI-SPI analog input and relay output modules, this system has up to 4 zones of water leak monitoring using water sense cable, and up to 4 temperature sensor inputs for hot water tank supply lines, ambient and output temps.
Three levels of kits are offered, just add a Raspberry Pi!


PLC Starter Kits for the Raspberry Pi
PLC Starter Kits are now available for automation projects. Three input styles are featured:
8 Channel 4-20mA Input.
8 Channel Temperature Input
8 Channel Isolated Digital Input.
Each Kit comes with a 4 channel relay output module, power supply and DIN rail
