Water Leak Detection Project with GrovePi  and Hologram Nova This project uses the Grove water sensor that can detect water leaks, spills, floods, and rain. It also can send notifications using cellular network. Things used in this project: Hardware components: Raspberry Pi Zero W or WH GrovePi Zero  Grove Water Sensor Grove LCD RGB Backlight Hologram SIM Software Apps: GrovePi  Python Hologram CLI Water sensor module from Grove system provides  the ability to detect if there is any water leak by measuring conductivity. The water sensor traces have a weak pull-up resistor of 1 MΩ and it pulls the sensor trace value high until a drop of water shorts the sensor trace to the grounded trace. GrovePi Zero is a HAT from Dexter Industries   that allows Grove Water sensor to connect to Raspberry Pi zero with out needing soldering or breadboards. One can plug in the Grove water sensor start programming. Grove water sensor works with digital I/...

GrovePi and Hologram Nova CLI Installation on Raspberry Pi Zero Raspberry Pi Zero W (or Raspberry Pi  zero WH ) is one of the smallest and ultra-low-cost computer  available that has both Wi-Fi and Bluetooth available. Because of its potential, available software and community support, it can be used in a wide number of IoT and robotics projects.     The main difference between Raspberry Pi Zero W and WH is that Raspberry Pi Zero WH comes with pre soldered header. It is important to have the GPIO pins available with a Raspberry Pi Zero W(H), before integrating with Grovepi Zero kit. If one starts Raspberry Pi Zero W, instead of WH, solderless Raspberry Pi pin headers can used used to attach the pins as an alternative to soldering the pins.   GrovePi Zero from Dexter Industries is an add-an board for Raspberry Pi zero W that allows various Grove sensors directly to the board. There exists a number of Grove sensors such as temperature, humidity, air q...
